Configuring the DIR-300 / NRU / B7 router
Connecting Wi-Fi router D-Link DIR-300 NRU rev. B7
The newly purchased and unpacked router is connected as follows: the provider's cable (in our case, Medialan) is connected to the yellow port on the back of the router, signed by the Internet. We plug the supplied blue cable with one end into any of the four remaining slots of the router, with the other into the connector of the network card of your computer. We connect power to the router and wait for it to boot, and the computer will determine the parameters of a new network connection (do not be surprised that it is "limited", as it is necessary).
Note: when setting up the router, do not use the Medialan connection on your computer to access the Internet. It should be disabled. Subsequently, after configuring the router, it is also no longer needed - the connection will be established by the router itself.
It will also not be superfluous to make sure that the parameters are set in the LAN connection parameters for the IPV4 protocol: get the IP address and addresses of DNS servers automatically. To do this, in Windows 7, click on the connection icon at the bottom right, select "Network and Sharing Center", then - change adapter settings, right-click on "Local Area Connection - properties, and make sure that there are no or static addresses. In Windows XP, the same properties can be viewed in Control Panel - Network Connections. It seems that the main reasons why something might not work, I took into account. Let's go further.
Setting up a connection in DIR-300 rev. B7
The first step to configure PPOE (this protocol is used by Medialan) on D-Link DIR-300 is to launch your favorite Internet browser (Internet Explorer, Google Chrome, Mozilla Firefox, Safari on Mac OS X, etc.) and go to the address 192.168.0.1 (enter this address into the address bar of the browser and press enter). As a result, we should see a request for a username and password to enter the admin panel of the DIR-300 B7 router.
Login and password for DIR-300 rev. B7 The standard login is admin, the password is the same. If for some reason they do not fit, then perhaps you or someone else changed them. In this case, you can reset the router to factory settings. To do this, press and hold something thin (I use a toothpick) for 5 seconds the RESET button on the back of the router. Then repeat the first step.
After entering the login and password, we will get to the settings menu of the D-Link DIR-300 rev. B7
D-Link DIR-300 rev. B7 - administration panel
Here we need to select "Advanced settings", after which you will see a page on which the model of your Wi-Fi router, firmware version and other information will be displayed.
In the top menu, select "Network" and get to the list of WAN connections.
In the image above, there is one WAN connection in this list. Click on the WAN connection, you should have the following settings: connection type (Dynamic IP), you also need to check the box - Obtain DNS server address automatically. The Mac address will need to be cloned as there is a binding by mas-addresses. We press to save.
After saving the WAN settings, click the add button in the lower right corner and go to the main WAN settings. This time we select PPPoE in the "Connection type" field. Then, instead of the standard connection name, you can enter any other (for example, for me - Medialan), in the "Username" field, enter your login from the Medialan Internet, in the fields for the password and password confirmation, respectively. Check the Keep Alive checkbox and click "Save". On the next page, where the newly created connection will be displayed, we will again be prompted to save the configuration. We save.
Now, if all the operations above were performed correctly, if you did not make a mistake when entering the connection parameters, then when you go to the "Network" menu to the "WAN" tab, you should see the following happy picture:
Pay attention to the mark in the item "Default gateway", by default there should be a PPPoE connection you created. If all three connections are active, then this indicates that the most basic thing for configuring D-Link DIR-300 NRU rev. We have successfully completed B7 and can proceed to the next step.
Setting up a WI-FI connection DIR-300 NRU B7
In general, a Wi-Fi wireless connection can be used immediately after turning on the router to the network, but in most cases it is useful to configure some of its parameters, in particular, set a password on the Wi-Fi access point so that neighbors do not use your Internet. Even if you are not sorry, this can affect the speed of the network, and the "brakes" when working on the Internet, most likely, will not be pleasant to you. We go to the Wi-Fi tab, basic settings. Here you can set the name of the access point (SSID), it can be anything, it is desirable to use the Latin alphabet. After this is done, click change.
Now go to the "Security Settings" tab. Here you should select the type of network authentication (preferably WPA2-PSK, as in the picture) and set a password for your WiFi access point - letters and numbers, at least 8 characters. Click "Change". Done. Now you can connect to the Wi-Fi access point from any device equipped with the appropriate communication module - be it a laptop, smartphone, tablet or Smart TV.
UPD: if it doesn't work, try changing the LAN address of the router to 192.168.1.1 in settings - network - LAN.
What is needed for TV from Medialan to work In order for IPTV from Medialan to work through a router, go to the first page of the DIR-300 NRU rev settings. B7 (for this, you can click the quick setting in the lower right corner) and select "IPTV Settings Wizard". It remains only to choose the port to which you will connect the IPTV set-top box. We press to change.
That's probably all, do not forget to save the router settings!
If you want to get rid of annoying cables, not be tied to one place of work on a computer / laptop, easily move all computer equipment, you need to purchase and configure a Wi-Fi router. This series of articles on configuring various routers will help you easily set up a wireless Wi-Fi network at home.
In this article I will describe how to configure Wi-Fi using the example of the Dlink Dir-300 NRU B5 router. The first thing to do is to the last. Then you need to configure the network on your computer / laptop to automatic acquisition of IP-address and DNS-server.
After that, we connect via the Dlink web interface (this applies to those cases if you closed the web interface after updating the firmware). Enter in the browser (preferably using Internet Explorer or Mozilla Firefox) 192.168.0.1 login admin, password admin (by default).
After that we get to the Dlink Dir-300 NRU web interface. Click on the button "Wi-Fi Wireless Network Settings Wizard".
In the first settings window, check the box "Turn on wireless connection", I think it's clear why :). The MBSSID parameter (allows one access point to serve up to four wireless networks at once with different settings) and BSSID (this is the physical address of the access point (MAC address) for the corresponding network.). At home, these functions are used extremely rarely, which is why they were initially turned off, so we will leave them that way. Push "Further".
In the next window in the line Hide hotspot We do not check the box, in the SSID line we write the name of the wireless network, select the country, leave the channel auto or indicate the free one, how to determine the free channel is described in the article How to select / change the wireless channel on the router / router
... Select wireless mode «
802.11 b / g / n mixed»
, so that various devices can connect to Wi-Fi, if the line "Maximum number of clients" Leaving 0 means that an unlimited number of devices can connect to Dlink Dir-300 NRU, if you specify, for example, the number 5, then the maximum number of devices can connect to the wireless network will be no more than 5. 
In order for all devices, both new and outdated, to connect to a Wi-Fi network without problems, we select network authentication "WPA-PSK / WPA2-PSK mixed".
In the PSK encryption key line, enter the password, which will need to be entered in order to be connected to the Wi-Fi network (I recommend using a complex password, at least 8 characters with letters, numbers and special characters). All other settings are related to encryption and I recommend leaving them by default. 
In the next window, we look at all the settings we specified, if everything is indicated correctly, click "Save" otherwise press "Back" and fix it. 
Now you need to save the settings on the Dlink Dir-300 NRU, for this, press the button from above "Save".
This completes the Wi-FI setup on the Dlink Dir-300 NRU router, close the browser window, turn on Wi-Fi on the device, and find our network. 
Enter the password and enjoy the Internet wirelessly.
After configuring the router, you can start configuring the local network to

More and more gaining popularity. And this is not surprising, because this is a very convenient way to connect to the Internet and link various devices, because no need for wires.
But, using a Wi-Fi network, do not forget about its safety. If you still do not have a password for Wi-Fi or it is too simple, perhaps a neighbor's child has long hacked your network and uses the free Internet for pleasure.
Of course, you may be a very kind person and you do not feel sorry for anything for your dear neighbors, but then you should not complain that your favorite sites have begun to load poorly.
If you still decide to secure your network, let's figure out how to put a password on Wi-Fi.
Where is the Wi-Fi password set?
A router (router) is the most common device when using Wi-Fi technology, so we will consider how to set a password on this particular device.
Now there are many router manufacturers on the market (D-Link, TP-Link, Zyxel, Asus, etc.) and even more different models of these devices. Therefore, within the framework of this article, we will not consider setting a password for all these models, but we will analyze this procedure using one of the popular D-Link DIR-300 routers as an example.
The settings of most modern wireless routers are opened using an Internet browser. This can be done on a computer, laptop, tablet, or any other device that is wired or wirelessly connected to the router.
It is advisable to perform this procedure on a device that is connected to the router via cable. The fact is that if you are connected via Wi-Fi, when you change the password, you will disconnect from the network and you will have to re-enter the settings.
In order to open the settings we need, you need to enter the device's IP address in the address bar of the browser. Most manufacturers use standard IP addresses, but some may have their own specific address.
The most common router IP addresses are:
- 192.168.0.1
- 192.168.1.1
- 192.168.2.1
- 10.0.0.1
- 10.0.1.1
If one of these addresses does not suit you, then you can find it in several ways:
- Look at the case of the router. Typically, manufacturers write the IP address of the router interface on a sticker on the bottom of the device.
- Examine the instructions or CD that came with the kit.
- Search the Internet for information on your router model.
It is possible that you have a non-standard IP address. In this case, you need to find out this address from the person who set up the router for you or reset the device to factory settings.
Entering the router settings
After you have determined which IP address is suitable for your device, enter it in the address bar of your browser.
If the connection to the router was successful, a window for entering the username and password should appear.
For most routers, the default username and password are "admin". D-Link DIR-300 is no exception. Therefore, you need to enter this word in both fields and click the "Login" link.
If after these steps you did not manage to enter the device settings, then either your router has different login data, or these data have been changed.
If you do not know the name and password to enter the device, then there are 2 options:
- As in the case of the IP-address - look at the case, read the instructions, search the Internet.
- If the first point does not help, then you need to reset the router to standard settings using a special button on the device.
Setting a password for Wi-Fi
Once you have entered the router interface, find the "Security Settings" item in the "Advanced Settings" section. In the settings of other models of routers, the menu will look different, but similar items can be easily found by the keywords wi-fi and security.
On the Security Settings page, you need to set the value of the following items:
- Network authentication
- Encryption key PSK
- WPA encryption
In the "Network authentication" field, you need to choose which authentication technology will protect your wi-fi network. WPA2 is currently the most secure authentication method for a wireless network. Therefore, it is recommended to choose this particular item for reliable protection of your wifi.
You must not treat the choice of the password carelessly. The password should be complex enough, consist of letters in different registers and numbers. It is desirable that it was some kind of meaningless set, and not specific words. This combination is harder to crack and you don't need to memorize it. Write it down somewhere and use it when connecting new devices to your wireless network.
The next step is to configure WPA encryption. To do this, select an encryption algorithm in the "WPA encryption" field. It is recommended to choose AES as it is one of the most reliable.
After entering all the parameters, click the "Change" button to save the settings. Most routers require a reboot after changing parameters. Therefore, it will most likely be disconnected from the network and you will have to re-enter the password.
Checking Wi-Fi operation
After restarting the router, you will need to reconnect to the network on all devices and enter a new password.
If an error occurs when connecting, then, most likely, the old parameters for connecting to wifi have been saved on your device. To fix this problem, you need to remove your network from the list of connections and re-search for access points. After your network reappears in the list, connect to it and enter a new password.
The D-Link DIR 300 NRU router is an updated model of the previous version of the DIR 300. All network devices of this brand are of good quality, an attractive and simple interface and, most importantly, a pleasant price. Let's find out what is remarkable about this model with the most common modifications B5 and B7, how to install it for home use and, if necessary, flash the device.
The router is often used for a home network
This router differs from the previous model in support of the 802.11n standard. In this device, the maximum speed is up to 150 Mbps, which is quite enough for home use. Externally, the router looks pretty standard, the interface provides 4 LAN ports for creating a local network, 1 WAN port, a reset button to return to factory settings.
Due to the external location of the antenna, the device provides an optimal Wi-Fi signal coverage area. The router is quite simple to configure or reflash for any subscriber, which makes it even more attractive among other models of network equipment. It also has its own zest - in addition to standard functions, it is possible to enable or disable a connection on a schedule.
Configuring the router
To install hardware and configure Wi-Fi, you should follow these steps:
- Enter the device parameters interface - for this, enter your IP address in the address bar of the browser (in most cases it is 192.168.0.1), after which you need to enter the word admin in the login field, the password must be left blank.
Note. These actions will give a result if the D-Link DIR router was not previously configured. If you need to re-configure, return it to its original state - before starting the parameters, hold down the reset key for 20 seconds, after which there will be a return to the factory settings.
- To set up a Wi-Fi connection, select the section with the same name in the menu, select the main settings tab.
- In the window that appears, enter the data to activate the connection - the name of the network, the country where you are, the channel and the type of wireless mode.

If you need to create new parameters, it is advisable to select the “Add” button and fill in the data in the window that appears - their content depends on the provider. For each of the types of PPPoE, PPtP, NAT connection, you need to enter certain data, which is in the contract from the service provider - using the form, you can consistently enter all the necessary information.
You can check the connection status on D-Link DIR in the “Status” section, “Network statistics” tab.
Setting a password
In order to secure your network, install the key that you will need to enter to connect to the Internet. This is done as follows:
- From the Wi-Fi menu, select the Security Settings tab.
- Mark the checkbox of the WEP enable line, after which the data for setting the password will appear.
- In the list of network authentications, select the WPA-PSK / WPA2-PSK mixed encryption type from the drop-down list - it is the most reliable for protecting the network from hacking.
- On the next line, enter your passkey - make it complex enough to prevent unauthorized users from connecting to your connection.
Additionally, it is advisable to secure not only the network, but also the router's configuration menu itself, by changing the standard login and password data to your own combinations. This is done like this:
- Go to the "System" section, open the "Administrator password" window.
- Enter new combinations to access the settings, after which you will need to re-enter the parameters menu using the login and password you just set.
Saving changes
In the parameters of the router there is a separate menu for saving changes or returning to factory settings, it is located in the “System” section, in the “Configuration” line. Here you can save the changes made, return to the initial settings or save the file with the current data in order to restore the connection later if necessary.
Installing new firmware
If you want to update your router software, do the following:
- Find and download the firmware file from the World Wide Web, the main thing is to choose the right software version, focusing not only on the model number of the router, but also on the hardware revision of the device, the data about which is written on the back of the router in the form of a H / W combination. There are different versions - B2, B5, B7 and others, they all differ from each other.
- Go to the router menu through a browser using the IP address.
- Open the "System" section, select the "Software update" tab.
- A line will appear in the window to indicate the path to the new firmware file for hardware revision B5, B7. Find it on your computer, then click "Update".
