Dir 300 as a repeater on native firmware. Setting up a WiFi repeater (repeater) for a wireless network

A Wi-Fi router is currently owned by many people who actively use the Internet connection. In today's offices, routers are considered a mandatory element of the infrastructure, providing access to the Internet for many users. It is often necessary to connect a device as a client. In client mode, the router independently connects to the existing wireless network and distributes the Internet from it to connected devices.

Why might you need this mode? For example, you have 2 stationary PCs and 1 Smart TV that only supports wired connections. It is not very easy to route network cables from the wireless router due to the location of the latter. It is much easier to use the D-Link DIR-300.

The client mode can be configured in three different ways:

Enabling client mode in standard firmware

In the instructions given here, the client mode setting on the DIR-300 is carried out on the equipment, the settings of which are reset to standard... In addition, all procedures are performed on a wireless router that is connected to a PC.

Flashing DD-WRT Router

DD-WRT is a free firmware for wireless routers based on BroadCom / Atheros / Xscale / PowerPC microchips. You can download it at this link https://mdex-nn.ru/uploads/dlink-dir300b-factory-webflash.bin. The firmware for routers of revision B1 is performed as follows:

1. Enter in the search bar of your web browser 192.168.0.1 ... Enter the data for authorization. Update with the firmware file via the device menu.
2. At the 1st launch of the firmware Enter login and password administrator.
3. You can customize the equipment.

For revision A devices, the firmware must be carried out acrossTFTP.

Stage 1. Flashing the D-Link Dir-300 B1

The factory firmware does not provide for the ability to operate the router as a repeater, however, craftsmen from the site http://www.dd-wrt.com/ have developed a customized firmware that turns this simple $ 20-35 $ router into a versatile router with wide capabilities. So, first of all, make sure that the revision of your router is B1, this information can be seen either in the web muzzle (in the upper right corner of Hardware Version: B1), or on the back of the device itself.

We download the latest version of the special firmware (download from the village / download from the official website) from the site of the craftsmen in the downloads section, which the original web muzzle can eat. In the future, for flashing, you can use the file intended directly for the dd-wrt web interface (download from our website / from the official website).

To update the firmware, go to the web-face of your router, as usual, at the address (if not changed): 192.168.0.1 (standard login - admin, no password is set). In chapter Maintenance -> Firmware Update press the button to select the firmware and select the previously downloaded file dlink-dir300b-factory-webflash.bin... Waiting for the button Upload... We are waiting for a few minutes until the new firmware completely takes over the router.

Stage 2. Configuring the source router (MegaFon E5830)

We go into the router through the browser ( 192.168.1.1 - default address) -> Customization -> Wi-Fi settings -> Basic Wi-Fi Settings... The channel (frequency range) is automatically selected by default, but since our two routers must work synchronously, this does not suit us, and we set a specific channel, For example 6 ... If you have encryption configured on your router, take a look also here: Customization -> Wi-Fi settings -> Configuring Wi-Fi Security, remember what type of encryption you have and remember or (if you forgot) set a new key.

Stage 3. Configuring D-Link Dir-300 B1 DD-WRT

After flashing the router, we will enter the new web muzzle at a different address. 192.168.1.1 ... When you first log in, you will be asked to set a new username and password, enter them at your discretion or leave the fields blank. You can immediately go to the interface settings and select Russian, but personally I left the usual English.

3.1. Go to Setup - Basic Setup.

In the WAN Connection Type, select the following settings:

Connection Type- Automatic Configuration - DHCP

Local IP Address is the network address of your repeater. I put the DiR-300 repeater in a different subnet (the second to last digit of the address is responsible for the subnet - 2): 192.168.2.1 , and as Gateway indicated the address of the source router MegaFon E5832S (by default it 192.168.1.1 ). Local DNS - duplicate the source address - 192.168.1.1 ... Subnet Mask standard - 255.255.255.0 .

We press Save & Apply Settings

3.2. Go to Status -> Wireless.

Press the button Site Survey(the main router Megafon / Huawei E5830 must already be turned on !!!). Push Join opposite the found access point (in my case, it is MegaFon E5830-35a2). A message will appear stating a successful network connection ( Successfully joined the following network as a client: MegaFon E5830-35a2).

We configure everything as follows:

Wireless Mode- Repeater

Wireless Network Mode- BG-Mixed

Wireless Network Name (SSID)- should have been automatically received, if not, then enter the name of your access point - the source. In my case, this is MegaFon E5830-35a2.

Wireless Channel- must be the same as what we have chosen for the source router. In my case, this is the sixth channel.

We press Save & Apply Settings

Additionally: if you have encryption configured on the source router, then do not be too lazy to go to the Wireless Security tab to set similar settings to what is on the source router.

After all these manipulations, our modified now_repeater D-Link Dir-300 B1 should automatically connect to the MegaFon E5830-35a2 access point and distribute the Internet to a wonderful distance. Your devices will see the router community as one single access point.

The advantages of this solution are visible to the naked eye:

D-Link Dir 300 is the cheapest branded router available today. It may be an old model, but it is reliable and stable. It has several ethernet ports and a dozen Wi-Fi devices can connect to it. At the same time, the source router considered in this article has serious limitations in terms of capacities and connections. You cannot connect to it via Ethernet, and the device does not support more than 4 Wi-Fi devices at the same time. Not to mention the fact that it starts to choke and glitch from a high load from several sides. With this solution, you can connect computers via an Ethernet cable that do not have Wi-Fi TVs. And the range of your network has approximately doubled.

Tips if nothing worked:

Try to tweak everything without setting the padding, in test mode, to make sure everything else is okay.

Make sure to press buttons at each step Save and Apply Settings, and one and the other.

Reboot both devices after applying the settings. Sometimes it helps.

The article describes way to expand the coverage area of ​​a wireless Wi-Fi network based on Asus and D-link equipment, home or small office class. For instance, Asus WL-320gE, Asus WL-520gU and D-Link DIR-300... Often indoors (office, apartment with many concrete walls, two-story rooms), the signal from the 1st router is not strong enough to confidently cover the entire workspace. The way out is to become installation of a repeater (repeater or amplifier) ​​Wi-Fi signal.

One solution to the problem is to install separate routers (access points) in adjacent rooms with different networks. In such a situation, different parts of the network can get fast access to the Internet, but cannot interact with each other. For this option, in principle, it is possible, but for the office it is categorically unacceptable.

So, we need a stable Wi-Fi network throughout the office space. For this we need to have two devices - WiFi router and WiFi hotspot with repeater function.

Wireless Distribution System (WDS) technology

Allows expand the coverage of a wireless network by combining several WiFi access points into a single network without the need for a wired connection between them (which is mandatory with a traditional network design). You can use the creation of virtual Wi-Fi access points,.

Negative sides WDS :

• network bandwidth drops by up to 50% compared to a regular connection.
• the speed of work on WiFi decreases since one channel is used to connect points
• compatibility issue between different manufacturers
• encryption is only WEP.

Positive sides WDS :

• no wired connection between Wi-Fi hotspots
• saving MAC addresses of network clients

WDS operates on the basis of MAC addresses by analogy with a network switch - a switch. URE- this is a signal repeater, the signal is retransmitted without processing, like a wired repeater - by a hub, when the received packet is simply repeated to all ports, or with an antenna crab.

Configuring the Asus Wl-520gU router

For example, the Asus WL-520gU router is connected to a wired Internet provider and will act as a gateway for other computers on the network. The address of the Asus WL-520gU router in the local network is 192.168.1.1. It will also act as a DHCP server on the local network. But the main thing is that in the same network the router and the access point are not simultaneously DHCP servers.

Configuring D-link DIR-300 in Wi-Fi Repeater Mode

When configuring d-link dir-300 as a Wi-Fi signal repeater, the configuration of the second access point remains unchanged. Recommended before setting.

Alternative firmware D-link DIR-300

DIR-300 with factory firmware does not possess Wi-Fi signal relay mode... Searching for an official D-Link firmware with repeater support is useless. Therefore, let's pay attention to the project DD-WRT firmware at www.dd-wrt.com.

DD-WRT- it free firmware for wireless routers based on BroadCom, Atheros, Xscale, PowerPC chips. It was originally developed for the Linksys WRT54G series of routers (including the WRT54GL and WRT54GS) and is a miniature operating system based on the Linux kernel. Distributed under the GNU GPL v2.

First you need reflash DIR-300 with DD-WRT firmware... There are descriptions of various ways of firmware this router. DIR-300 Revision B1 can be flashed directly from the standard administrative web interface. If you have firmware problems, you can try change the router from crash mode.

Configuring D-link DIR-300 in Repeater Mode

After successful flashing, go to configuring the router in the Wi-Fi repeater mode... During the first connection to the flashed DIR-300 at the IP address 192.168.1.1, you will be asked to set a new username and password for subsequent configuration.

Instructions for installing DIR-300 in the Wi-Fi repeater mode

Installation - Basic Settings

• disable the WAN interface
• DHCP server
• we register the network settings for our repeater. It must be on the same network as the main router. For example, there is a network 192.168.1.0/255.255.255.0, the gateway and DNS server is a router with an IP address of 192.168.1.1. For the Dir-300 repeater, we knock out a free static address, for example 192.168.100.1, which is not included in the distribution range of the DHCP server.
• We save the settings.

Wi-Fi setup

• Wireless Type - Repeater Bridge,
• the SSID name is the same as that of the relayed network
• We save the settings.

Configuring a secure network with WEP encryption

• Wi-Fi network security
• register a similar encryption algorithm and network key that is used in the expandable network!
• We save.

As a result, we have configured Wi-Fi network repeater based on DIR-300. If you have any questions or want to contact the ITcom specialist's contact phone number.

D-LINK network equipment is well known both in Russia and abroad. In a wide range of devices, the entry-level wireless router D-LINK DIR-300 stands out. Thanks to its low price, excellent reliability and good technical characteristics, it became the first truly affordable home Wi-Fi router. The model turned out to be so successful that it is still being produced. What are the differences between routers of different years of release, how to connect and configure them for the most efficient work - the topic of our article.

Router appearance, technical characteristics

D-LINK DIR-300 is an entry-level router (router) designed for use in a home or small office. It allows you to connect clients to the Internet both via cable (twisted pair) and using a wireless connection (WiFi). Four computers can be connected using a cable connection, and any number of clients using Wi-Fi. However, with each client connected via Wi-Fi, the access speed will drop. If one client can run at 150 Mbps, two are already at 75 Mbps, and so on.

The router has been on the market for over ten years, during which time three generations (revisions) of this router have been released.

DIR-300 revision A

The oldest router in the lineup, long out of production, although you can buy it on the secondary market. The b / g wireless module provides speeds up to 54 Mbps in ideal conditions.

DIR-300A is a veteran in the line of routers

The Ethernet ports of the router allow organizing a local network with an access speed of up to 100 Mbps. But the speed of the Internet for clients of the local network will be almost two times lower: a small amount of RAM and a weak processor allow DIR-300 rev. A process internet traffic at a speed not exceeding 50 Mbps. If you are connected to the Internet with a faster tariff plan, you should change your old router to a more efficient one.

Branded gray-orange interface - the hallmark of early models of D-LINK routers

DIR-300NRU revisions B1, B3, B5

The abbreviation NRU in the model name means that the wireless module complies with the N standard and can provide a theoretical Wi-Fi speed of up to 150 Mbps. The RU prefix indicates that the model has been developed and produced for the market of the countries of the former CIS.

DIR-300NRU B1 - austere appearance and 150 Mbps over the air

A dual-core processor with a clock frequency of 350 MHz and 32 megabytes of RAM allows you to install alternative firmware on these routers, such as OpenWRT and DD-WRT, which significantly expands the capabilities of the router and improves its stability. The processor speed is sufficient to work with tariff plans up to 100 Mbps.

OpenWRT - the world's most powerful router software

DIR-300NRU revisions B7, D1, A1

These router flavors are built on a new hardware platform, so alternative firmware won't work on them. But the standard software was also significantly redesigned: the usual web interface was changed to a new one, with an interactive map of client connections and the ability to change many settings without restarting the router.

New D-LINK software saves the user from manipulating alternative firmware

Models B7 and D1 are produced in a vertical version of the case, and model revision A will certainly be remembered by you for its appearance in the form of a black cylinder.

DIR-300NRU A1 - space design and very terrestrial characteristics

DLINK DIR-300A was the first wireless router that I purchased almost 10 years ago. Simple and unpretentious, it worked without shutting down for almost 5 long years, without failures and without "freezing", and only connecting to another, faster Internet provider made me replace my old friend with a new router. But thanks to the DD-WRT firmware, the veteran is still in the ranks, working as a wireless network repeater in a country house. Low speed has become the trump card of this router - it almost does not heat up, which means it can work stably in difficult climatic conditions, for example, in hot summers.

Preparing the router for work

In order for D-LINK DIR-300 to connect all your devices with a single home network and provide each client with access to the Internet, you need to take a number of preparatory measures. The router must be connected with cables to the provider's network and home computers, and the network cards of the clients must be configured to automatically receive addresses. After that, you can configure access to the Internet and create a wireless network.

Connecting a router, preparing for configuration

The router connection diagram is simple: the provider's cable is plugged into the Internet socket, computers of the local network - to the LAN1-LAN4 network connectors. Smartphones, tablets, and other wireless devices connect using a Wi-Fi network.

Creating a home network based on DIR-300NRU

Configuring a computer network card to work with a router

A DHCP server is automatically activated in the router "out of the box" - the router will itself issue network addresses to connected computers. Therefore, before you start configuring the router, it will be useful to make sure that the network adapter of your computer or laptop is configured to automatically obtain a network address.

1. Click on the "Start" button with the right mouse button and select "Network Connections" from the user menu.

   Calling up network connections from the user menu

2. Select the required adapter in the network connections window and open its properties with the right mouse button.

   The properties of the network adapter contain settings for the TCP / IP protocol

3. Select TCP / IP settings from the list of protocols and open them for editing.

   TCP / IP is the main conductor of the wireless network

4. Configure the automatic acquisition of the network address and DNS server address as shown in the screenshot, and then click OK.

   Automatic address acquisition is set

Modem web interface, configuration and access protection

The modem's web interface, through which most of its settings are performed, is located at 192.168.1.1. The username is admin, and the default password is empty, so you don't need to enter it. Change the access password immediately after the initial setup of the modem. This will protect your network from third-party interference.

1. Switch to advanced settings mode.

   Quick settings and connection status on the main page of the modem

2. In the "System" section, follow the link "Administrator password".

   Access to system parameters is hidden in advanced settings

3. Enter your password and click the "Apply" button.

   Enter your password and confirmation in the field below

Internet Service Provider Connection Settings

The router's web interface allows you to configure an Internet connection both in a semi-automatic mode (using the setup wizard) and in a completely manual mode. Before starting the setup, make sure your internet connection is activated by your service provider. To do this, try connecting to the Internet without a router by connecting the provider's cable to the computer's network card.

Fast Internet Connection Wizard

For a technically unprepared user, D-LINK has implemented a Click'nConnect tool in the router software, which requires the user to go through just three screens of simple settings with a choice of connection type and authorization parameters. The router will automatically determine the rest of the connection options, provided that the cable of the Internet provider is already connected.

1. Open the web interface by entering 192.168.1.1 in your internet browser.
2. In the "Network" section, follow the Click'nConnect link.

   All step-by-step "wizards" are launched from the quick settings page

3. Check if the ISP cable is connected to the WAN port of the router.

   Make sure the ISP cable is connected to the WAN port

4. Select from the list the type of connection that your Internet provider uses, for example - PPPoE.

   Select internet connection protocol

5. Enter the authorization parameters from the contract: login, password and name of the VPN server (if an L2TP or PPTP connection is used). In order to access additional settings, move the switch in the lower left corner of the window to the "Details" position.

   Enter your username and password from your contract with the provider

6. Check the settings in the system report window and if there are no errors, press the "Save" button.

   Check if the settings are correct and click the "Save" button

If you are used to "keeping your finger on the pulse" and want to make the settings manually, you can do this by switching to the advanced settings mode.

Through the advanced settings menu, the connection to the Internet service provider is configured

L2TP configuration

L2TP is a type of VPN in which the "tunnel" can be established not only over TCP / IP, but also over lower-level protocols: ATM, X.25 and Frame Relay. The protocol provides encrypted traffic, so L2TP connections are used more often in corporate networks than for private individuals to connect to the Internet.

1. Manual configuration of connections comes from the advanced settings menu

2. Create a new internet connection

3. Enter the account parameters in the window that opens: login, password and VPN server address.

4. For static connection, enter the IP addresses assigned by the ISP

5. Click the Apply button.
6. Returning to the window with the list of connections, activate the created entry as the default connection.

   Make the created entry active by default

PPPoE setup

PPPoE connection is the most common among Internet providers, and it is easier to set up than others, since only a username and password are required from the authorization parameters.

1. From the advanced settings menu, go to the WAN link in the Network section.

   For PPPoE connection, follow the WAN link from the advanced settings menu

2. In the list of network interfaces that appears, click the "Add" button to create a new connection.

   Create a new connection using the "Add" button

3. Enter the account parameters in the window that opens: connection type (PPPoE), username and password.

   Set the connection type to PPPoE, and take the login and password of the connection from the contract with the provider

4. If a digital TV set-top box or "smart" TV is connected to the router, set the IGMP checkbox to the on position.

   Activate the options for watching IPTV. Don't forget to assign one of the LAN ports to connect your TV box

5. Click the Apply button.
6. Returning to the window with the list of connections, activate the created entry as the default connection.

PPTP setup

Configuring a PPTP connection is no different from the L2TP configuration discussed earlier. In the same way, two types of connection are supported: with static and dynamic addresses. Login, password and VPN server name are enough for authorization. Please note that this type of connection creates a heavy load on the router processor. If your tariff plan provides for a connection with a speed of 90 Mbps or higher, you should think about buying a new, more efficient router.

1. From the advanced settings menu, go to the WAN link in the Network section.

   Manual configuration of the PPTP connection comes from the advanced settings menu

2. In the list of network interfaces that appears, click the "Add" button to create a new connection.

   Create a new PPTP access connection

3. Enter the account parameters in the window that opens: login, password and VPN server address. If the symbolic server address is not provided by your ISP, enter it in TCP / IP address format.
4. If the secondary connection is static and not dynamic IP, enter the DNS server addresses, network address, netmask, and gateway address.

   For a static PPTP connection, enter the IP addresses assigned by your ISP

5. Click the Apply button.
6. Returning to the window with the list of connections, activate the created entry as the default connection.

Static IP configuration

If you connect to the Internet with a static IP address, your login and password are not required. In the parameters of the created connection, you enter the address received from the provider, the subnet mask and the gateway address, after which the router is ready to work.

Home network and wireless settings

After the router's Internet connection is configured, it remains to configure the wireless network and the connection of wired clients, thereby completing the creation of the home network. Never create a wireless network without password protection, even if you have MAC address binding enabled. An attacker can easily clone the MAC address and connect to your network.

Configuring Wi-Fi (creating an access point, changing a password)

The second step after setting up the connection to the provider will be to enable and configure the wireless access point, which will allow you to distribute the Internet to devices with a WIFI module: laptop, tablet, smartphone.

1. It is better to configure the wireless network from the advanced settings menu.

2. Click the "Advanced Settings" button.
3. Make sure the wireless enable slider is in the green (on) position.

   Make sure WI-FI is on

4. Open basic wireless settings. Here, set the name of the wireless network, the broadcast channel, and the name of the guest network. Guest network clients will receive internet, but will not be able to connect to the local network.

   Enter the network name and select the broadcast channel

5. Return to the main screen and open the wireless security settings. In them, set the type of encryption and password for accessing WIFI.

   Create and enter a password for the wireless network

6. Returning to the main screen, click on the save settings link in the upper right corner.

The password set for the wireless network is used by the router to encrypt the transmitted data. The more characters in the password, the more reliable the encryption, but the load on the router processor is also higher. The optimal key size is 8-13 characters.

Port mapping

Some users need to get access from the resources of their local network from the Internet. Access to home network folders, a picture from a home IP camera, remote administration with Remote Administrator or Team Viewer, and dozens of other useful applications. To organize the possibility of such access, so-called port forwarding is required, that is, the router connects the external network port and the internal port. Configuring port forwarding is easy using the modem's web interface functions.

1. Open an internet browser and go to the web interface of the router at 192.168.1.1.

   Add a new rule

2. In the window with the list of forwarded ports, click the "Add" button.
3. In the port settings dialog, fill in the following fields in sequence:
   
4. Click the Apply button in the lower right corner of the screen.

Setting up IPTV (digital TV)

Setting up IPTV allows you to select one of the four network ports for transmitting a digital video stream to it. This port can be used to connect a network media player, Smart-TV or digital TV set-top box.

A few months ago, family friends asked for help in connecting SmartTV to their home router - DLINK DIR-300. Connected using the IPTV Setup Wizard, the TV perfectly showed one and a half hundred digital channels, but none of the Internet services worked: youtube, mail, online cinema, even the weather forecast complained about the lack of an Internet connection and did not start. A study of the documentation suggested that for the simultaneous transmission of a video stream and Internet traffic to the port, it was necessary to set up a Dual Acsess connection, but the existing router software did not allow this, and the owners did not want to flash the router with an alternative firmware so as not to lose the warranty. Still, a way out was found: we connected a Wi-Fi adapter to one of the TV's USB ports and set up a connection to the router's wireless network through it. And through the Ethernet connection, there was a digital video stream. The price of the issue is about 500 rubles, and a new router with support for Dual Acsess would have cost much more.

LAN and DHCP Server Settings

Advanced mode of the router allows you to configure the parameters of the dhcp server, LAN and internal interface of the router.

Switching D-Link DIR-300 to repeater (repeater) mode

The stock software does not support switching the router to the repeater (repeater) mode. If you bought a new, more powerful router, and you want to use the old DIR-300 to expand your wireless coverage, you can try installing the alternative DD-WRT firmware, in which the repeater mode is configured in just a few clicks.

1. Install the DD-WRT firmware using the firmware restore (update) function.
2. Disable the WAN interface and DHCP server on the Installation tab (section Basic Settings). Enter the network setting data to the repeater. The device must be on the same network as the main router. We will have a network 192.168.128.0/255.255.255.0, the gateway to which is the machine with the address 192.168.128.5. It is also a DNS server. For the future Dir-300 repeater, a free address 192.168.128.2 was selected, which is not distributed by the DHCP server.

   Enter the details of the network address, subnet mask and gateway

3. Specify the type of wireless network as “Repeater-bridge”, and the name of the wireless network must be identical to the name of the network on the main router. In this case, your network is DizAr_net. Save the settings again.

   Firmware status page - repeater mode activated

Unfortunately, DD-WRT firmware does not support all DLINK DIR-300 models. On the project website, you can download the update images for revision A1 (the oldest is DIR-300) and for version DIR-300NRU of revisions B1-B3.

Video: Installing DD-WRT Firmware on D-LINK DIR-300

D-Link DIR-300 Administration

A router is a standalone device that can work for weeks without user intervention. If problems do arise, then you cannot do without the manipulations of the network administrator. You may need to reboot the router or reset it to factory settings, and in severe cases, even update the firmware.

Resetting the router to factory settings

You may need to reset the router to factory settings if the device does not work correctly and access to the web interface is impossible. Fortunately, all D-LINK DIR-300 routers have a hardware reset option.

Firmware update (firmware)

Updating the internal software will help resolve bugs, improve performance, and improve the stability of the router.

1. Check the revision of your router, this information is on a sticker located on the bottom cover of the device.

   The manufacturer's website contains firmware files for all revisions of the router

2. From the router's advanced settings screen, select the "Firmware update" link in the "System" section.
3. Use the "Browse" button to specify the path to the firmware file and click the "Update" button.

   Specify the path to the firmware file and start the update process

4. The router will start the update procedure, which will take about 10 minutes.

Be very careful when choosing a firmware file. Software from a router of a different revision or even an older version of the software may make your device completely inoperable when installed. It will be possible to restore it only at the service center.

Reboot the router

The easiest way is to reboot the router by turning off the power by unplugging its AC adapter. If the router is installed in an inaccessible place, you can also reboot it through the web interface.

Repeater WISP (Repeater Wireless Internet Service Provider) - for organizing shared access of office and home computers to the Internet, both via the Ethernet port and via wireless WiFi. I show it using the example of the DIR-300 NRU B5 model, firmware version: 1.2.94 - 1.4.3.

Firmware version: 1.2.94

Reset to factory settings.

Firmware version: 1.2.94. Whoever has a new firmware - 1.3.3, then you can return to version 1.2.94 by flashing first with version DIR_300NRUB5-1.2.93.fwz, and then immediately, without rebooting the router - DIR_300NRUB5-1.2.94.bin ( Firmware on ftp.dlink.ru).

• In the address bar of the browser, write 192.168.0.1 and go to the router using the login "admin" and the password "admin". We go to the menu "network" - "connections" - "LAN". There we change the IP address to another subnet - from 192.168.0.1 to 192.168.1.1 and do not forget to save all changes for any operations.
• In the same place, in the "connections", go to "WAN" and change the connection type to "IPoE", the physical interface to "WiFiClient", IP and DNS to "automatically" (perhaps you need to drive your settings as if you were setting up a wired WAN compound). Then "change" and "save".
• Turn on the wireless connection in the "Wi-Fi" menu.

• In the "Wi-Fi" menu, go to the "client" and turn it on. After automatic search for networks, a list of available networks will appear. "Click" on the network you need (in my case, it is DIR-620), if the required network is not found, change the position of the antenna and repeat the "search for networks". We remember the channel on which the network sits. Then "change" and "save".
• In the "basic settings" of the Wi-Fi menu, we manually set the channel of our selected network. We save everything.
• We check in "Statuses" "Network statistics". Everything should be "connected", if not, save and reboot the system.
• The next time you enter the router menu, do not forget to register the address 192.168.1.1.

Firmware version: 1.3.3

For this firmware, all settings and changes are made in the same way, so I will not repeat myself, just do not forget to connect the "client" to "wi-fi" first, otherwise the "WiFiClient_1" settings will be hidden.
Everything works for me, I was glad to help.

Firmware version: 1.4.0 - 1.4.9

And for this firmware, all settings and changes are made similarly to the previous ones, PrtScn pictures are shown below. For WiFiClient settings to appear in the "Network >> WAN" submenu, you must first go to the "Wi-Fi >> Client" section, then select a network and save it.

Simple reflector - reflector for router antenna

• In 5 minutes it is made from a regular can of beer-juice (see photo below).
• If the signal is caught with a vertical router antenna, you can use the already existing hole in the bank.
• We put the structure on the antenna and align it so that the distance from the antenna to the reflector is about 15-20mm.
• We are looking for the angle of rotation for maximum signal reception. To do this, click on "search for a network" in the "wi-fi client" after each change in the direction of the reflector (at least 2-3 times in one position, if the signal was weak).
• If you want to catch the reflected signal (the signal source is not in line of sight), then remember physics for the 5th grade - the angle of incidence is equal to the angle of reflection and set the reflector accordingly.
• I advise you to manipulate not only the reflector, but also the position of the antenna - my maximum signal reception was achieved in the recumbent position of the router's antenna, and even at an angle of 45 degrees to the window. In the vertical or other positions of the antenna, the network I needed was not caught at all, even with a reflector.
• As a result of such gestures, I achieved on my router an amplification of a weak reflected wi-fi signal from 15% (without a reflector) to a stable 39%, and the number of caught networks increased from 8 to 19 pieces.
• In the second photo, a test design of a directional antenna is screwed to the reflector for additional passive amplification of the wi-fi signal (I saw something similar on the Internet and decided to check how much more the signal would be amplified). On the knee, in 15 minutes, I wound ~ 5 cm transverse elements made of the same wire on a guide made of copper wire in a PVC sheath, only without a sheath, at a distance of ~ 3 cm from each other - more exact dimensions are available on the Internet.
  In your case, to improve the signal, such an antenna can be positioned both vertically and horizontally - it is experimentally located, regardless of how the router antenna itself will be located.
  As a result, another 5-7 new sources of wi-fi signal were added and the power of the network I needed rose to 44% and even gave a resonance a couple of times up to 55-60%.
