How to connect a dsl 2640u modem to a computer. Debugging a Wi-Fi network

After the user configures the D Link DSL 2640U, he gets a full and fairly fast one.

At the same time, among the additional tasks is the distribution of the received data using a wired and wireless connection.

The third is the provision of television using IPTV technology.

Thus, receiving a signal from the telephone network, using this modem, you can provide the entire apartment, house or office with the Internet.

Device features

The D-Link DSL-2640U modem is a device that, as a rule, comes with equipment for connecting the telephone Internet (although you can buy it yourself).

The device, which has the functionality of a conventional router, is used by various providers, including one of the largest - Rostelecom.

At the same time, it is also suitable for creating on 1-2 computers, and copes with more serious tasks:

• receiving data over a telephone cable with a maximum speed of up to 24 Mbps;
• Internet distribution using cables connected to the modem via 4 LAN connectors;
• creation of a wireless home or office network with the ability to simultaneously connect up to 10 devices operating according to 802.11 b / g / n standards (that is, in modes with a transmission and reception rate of 11 to 150 Mbps).

At the same time, complete information security is ensured due to the firewall using WEP, WPA and WPA2 technologies.

Rice. 2. Go to the router settings.

Things to know: By default, both the username and password are admin. If desired, you can set your own values, increasing the security of the network.

Setting up an ADSL connection

In order to set up a modem connection to the telephone network, you should know the information provided by the provider - the type of connection and interface parameters.

Most often, they are specified in the contract for connecting to the network. Sometimes for this you have to contact the technical support of the operator.

Procedure for setting up:

1. Open the item "Networks";
2. Go to the connection section and select the item "Add";
3. Creating a connection name (the easiest way is to leave this parameter unchanged);
4. Selecting the type of connection (as a rule, it is PPPoE, although some providers may have others - for example, VCI or VPI);
5. Entering other information provided by the provider.

Now, when the modem is connected to the network, all devices connected via cable will receive the Internet automatically - without passwords and additional settings.

However, to provide a wireless network, additional configuration is required.

Setting up Wi-Fi on the modem

And the wireless Wi-Fi line is still used to connect to the network of tablets, smartphones and laptops.

After rebooting the modem, you can connect all the necessary cables to it.

But, if for some reason the fourth port is also needed for a wired connection to the Internet of a computer, you will have to configure the DSL-2640U again, returning the last port to its previous capabilities.

Now every family has a computer, and not even one. For convenient use and access to the Internet, you will need a special router. A rather successful solution is to connect all the computers available in the room using a local network. For these purposes, you can purchase a special ADSL modem.

In the article, we will consider a successful (according to most users) model D-Link DSL-2640U. Let's talk about the advantages and disadvantages of the device, as well as customer reviews.

Specifications

The total weight of the model is 300 g. Power is supplied by a special cable that is connected to the network. There are about five indicators that provide comfortable operation.

Design

Its design resembles many other routers of the same type. In fact, it is a regular black box. On it you can see indicators that notify about the operating modes of the router. All of them are highlighted in green. As usual, all connectors and ports are located on the rear panel. A button to turn off the wireless Internet is specially built in. This makes the model easier to use.

On the rear panel is a special factory sticker, which is hard to miss. As soon as the buyer unpacks the model, he will immediately see it. The fact is that the sticker covers the entire panel, and in order to use any port or simply turn on the router, you need to tear it off.

Equipment

The package bundle of the DSL-2640U modem is rather banal. It includes a special set of cables that are responsible for accessing the Internet, etc. There is a network cable, a splitter, software for quick setup, and a user manual. The disk contains a utility that will obviously appeal to many buyers, although professionals treat it cold-bloodedly. Often, most configure the router on their own, without resorting to using this software.

Settings menu

Router D DSL-2640U is quickly and easily configured using the disk. After opening the program will ask you to decide on the provider. Then you need to enter your username and password. After a few minutes, when the program makes all the settings, a connection will appear. But there is one drawback - the modem activates the software in router mode. The fact is that this is not suitable for all types of Internet connections. That is why it is important to be able to configure the router yourself.

The configuration interface looks good. The design is good and clear. It should be noted that in previous models, the web setup is rather complicated, confusing, and the design is not attractive. It has become much more pleasant to work in the current one. Moreover, now all the settings menu has been translated into Russian. If desired, you can always switch to English.

Network creation

Creating a WAN is pretty easy. However, this requires a little knowledge and skills. Unfortunately, the instructions that come with the kit are not particularly informative. The setup algorithm is described there, but it is incomprehensible and does not help to solve the questions that have arisen in the process. It is also quite primitive, there is no description of all available functions and options. The manufacturer's logic is clear. He thinks in such a way that if the user has the skills to create a network, then please let him figure it out, and if the user is a beginner, it is necessary to work with the disk.

The DSL-2640U router makes setting up a wireless network quite easy. It is simpler than a WAN connection. If the provider does not require special settings, then generally no special actions will have to be done. By default, the wireless network is already activated and able to function. In this case, it is necessary to configure the network performance of the laptop or computer itself. If everything is fine with them, then the network will appear instantly.

By default, the wireless access point does not receive encryption. Therefore, if you need to password-protect it, you will have to understand a little in the settings menu. You should go to "Security" and look into "Network Authentication". There you need to set the desired key.

Modem operation

If a specific way of setting worries the consumer only in the first days of installing the router, then you will have to put up with its features of work and deal with them every day. It must be said that the DSL-2640U modem showed both good and bad sides. Let's consider in more detail.

The router functions well with a rather poor line. It handles a lot of signals and noise very well. The network works stably, without any failures.

If we consider the model as an access point, then it is worth noting that it functions at an average level. Performance indicators depend on the power of the applied signal. The external antenna is not connected, the native one is not removable. Unfortunately, the modem does not provide a fairly strong Internet signal. If you use it in a three-story house, then a stable and normal network will be only where the router itself is installed. In the back rooms the internet is poor and sometimes interrupted. Therefore, this model is not suitable for a private house. But for an ordinary apartment it will do just fine.

Switch D-Link DSL-2640U shows stable operation. All devices that are in the local network see each other perfectly and interact with each other. The modem can distribute not only its own Internet, but also received via an external port. The wireless network can work in the same mode.

Disadvantages in communication

What do consumers consider disadvantages? is not able to share and limit the speed of the Internet from other computers connected via a local network. Although this may not be very necessary in everyday life, however, the presence of this function will not hurt.

Another disadvantage consumers call a rather weak power supply. Unfortunately, it can burn out in just a year of use, which will result in additional spending. This is also a shame because the warranty for the device itself is 1 year. But many consumers note the following: the manufacturer, knowing about the problem, changes the power supply for free even after the grace period for service has expired. Perhaps this is due to the desire not to advertise this minus. If necessary, you are always allowed to try to fix the part yourself.

And the last serious drawback is the constant overheating of the DSL-2640U router. The firmware does not have a special function that will cool it. Due to the fact that the model did not receive a mount and stand for placement in a vertical position, the modem starts to heat up too quickly. The manufacturer could have easily corrected this problem or prevented it, but this did not happen. Therefore, many buyers place the modem in some kind of cool room. It can be a pantry, a window sill, a place on the refrigerator. However, not everyone has this opportunity. In general, overheating does not affect the operation of the router. It doesn't slow down, it doesn't crash. But still, you should monitor this so that the parts do not burn out.

Results

The D-Link DSL-2640U modem is considered a universal device, so it is easily suitable for use both at home and in offices. It doesn't matter what type of Internet, nor what set of devices is used. The model has not received much flexibility and functionality from the manufacturer, but it is quite easy to set up, it does not lose connection and does not hang.

The most common problem with this router is overheating, but it does not affect the functionality of the device. Many consumers advise him to buy, so do not worry! The DSL-2640U router, whose firmware has become much more convenient and pleasant, has long been in demand among domestic buyers.

One of the most popular devices today used to work correctly with the Internet, connected by the Rostelecom provider via a telephone line, is the DSL 2640u router. And today we want to figure out how to connect a DSL 2640u, and how to set it up.

Complete set of the D-Link DSL 2640u modem

When buying or receiving a router, the first step is to check its package. It is not extensive, and it is not so difficult to remember all its elements:

• Power Supply;
• Patch cord;
• Telephone cable crimped with connectors;
• Router directly.

When you are convinced of the completeness of the package, you can proceed to the next step, which consists in correctly connecting and turning on the device.

How to connect D-Link DSL 2640u to Rostelecom

1. Connect the power supply to the modem.
2. Connect the telephone cable to the corresponding port of the modem and the other end to the corresponding port of the splitter.
3. Connect the patch cord to the Lan port of the router and to the network card of the computer.
4. Plug the modem into a power outlet.
5. Turn the device on by pressing the corresponding button on it.

Hardware setup

Now that all the equipment is connected, you can start setting it up:

1. Launch the web interface of the router by logging in to page 192.168.1.1 in a browser using the username and password "admin".
2. Click on the "Advanced Settings" button on the main page.
3. Navigate to the "WAN" subdirectory under the "Network" section.
4. If there are any options in the netlist, remove them. After that, click on the "Add" button, which will allow you to create a new connection.
5. Specify the "PPPoE" parameter in the connection type field.
6. Port select DSL.
7. Set the name of the connection to "Internet" to navigate the available connections in the future.
8. Leave the VPI setting at 0.
9. Enter 33 for the VCI field.
10. The username and password are entered according to the agreement with the provider.
11. The authentication algorithm remains in automatic mode.
12. The MTU item is set to 1492.
13. The LCP interval is set to parameter 30.
14. LCP dips - 3.
15. Enable NAT, IGMP and Firewall by checking the appropriate checkboxes.
16. Save your changes.

Setting up IPTV on DSL 2640u from Rostelecom

Of course, the setup cannot be considered complete until all available services provided by the provider are working. Therefore, in order to bring the IPTV service into operation, users need to add one more connection in the Net=>WAN item. Its parameters are specified as follows:

1. Connection type - Bridge (Bridge);
2. Port - DSL;
3. Name is TV. You can specify any name, but it is this parameter that will allow you to navigate existing connections.
4. VPI is set to 0;
5. Enter VCI parameter 50;
6. The encapsulation method is specified by LLC;
7. The QoS setting is UBR.

After entering all the parameters, again click on the "Save" button.

Wireless setup

And finally, of course, you also need to take care of the correct configuration of the wireless network, because today it is simply impossible to imagine Internet access in a home or office that cannot be connected via Wi-Fi protocols. To this end, we perform the following actions:

1. In the main menu of the device's web interface, go to the "Wi-Fi" section.
2. Select "Basic Settings".
3. Specify the name of the access point in the field
4. Set the marker in the checkbox to enable the wireless access point.
5. Save your changes.
6. In the "Security Settings" section, select the WPA2-PSK network authentication type, and also specify the password for accessing the Wi-Fi point.

In general, the configuration algorithm for most routers is not much different. All actions take place in an individual web interface, and the selected parameters depend only on the requirements of the provider and user preferences. However, there are always some peculiarities. Today we will talk about configuring the D-Link DSL-2640U router under Rostelecom, and you, following the instructions given, will be able to repeat this procedure without any problems.

Before switching to firmware, you need to choose a place for the router in an apartment or house so that the LAN cable reaches the computer and various obstacles do not interfere with the Wi-Fi signal. Next, look at the back panel. A wire from the provider is inserted into the DSL port, and network cables from your PC, laptop and / or other devices are inserted into LAN 1-4. In addition, there is also a connector for the power cord and WPS, Power and Wireless buttons.

An important step is to determine the parameters for obtaining IP and DNS in the Windows operating system. Here it is desirable to put everything on "Receive automatically". It will help you figure it out Step 1 In chapter "How to set up a local network on Windows 7" in our other article at the link below, we go directly to the web interface.

We configure the D-Link DSL-2640U router near Rostelecom

Before configuring and changing any parameters in the router firmware, you need to log into its interface. On the device in question, it looks like this:

Quick Setup

D-Link has developed its own tool for quickly configuring its equipment, it is called Click'n'Connect. With this feature, you can quickly edit the most basic WAN connection and wireless access point settings.

1. Category "Start" left click on "Click'n'Connect" and click on "Further".



2. Initially, the type of connection is set, on which all further adjustments to the wired connection depend. Rostelecom provides the relevant documentation, where you will find all the necessary information about the correct parameters.



3. Now mark with a marker "DSL(new)" and click on "Further".



4. The username, password and other values ​​are also specified in the contract with the Internet service provider.



5. Clicking on the button "More", you will see a list of additional items that will need to be filled in when using a specific type of WAN. Enter the data as specified in the documentation.



6. When finished, verify that the marked values ​​are correct and click on "Apply".

Internet access will be checked automatically. Pinging is done through the google.com site, but you can specify any other resource and re-analyse.

D-Link offers users to activate DNS from Yandex. The service allows you to organize a secure system to protect yourself from unwanted content and viruses. The window that opens contains brief descriptions of each mode, so read them, put a marker in front of the appropriate one and move on.

The second step in the mode Click'n'Connect will create a wireless access point. For most users, it is enough to set only the main points, after which Wi-Fi will work correctly. The whole process looks like this:

As you can see, the task of quick configuration does not take much time, even an inexperienced user can cope with it. Its advantage lies precisely in this, but the disadvantage is the lack of the possibility of finer editing of the necessary parameters. In this case, we recommend that you pay attention to the manual setting.

Manual setting

It’s worth starting manual configuration with a WAN connection, it is done in just a couple of steps, and you will need to perform the following actions:

After making all the changes, do not forget to save them so that they take effect. Let's move on to the next section. "LAN", where changing the IP and mask of each port is available, activating the assignment of IPv6 addresses. Most of the settings do not need to be changed, the main thing is to make sure that the DHCP server mode is active. It allows you to automatically receive all the necessary data for working on the network.

This is where we are done with the wired connection. Many home users have smartphones, tablets and laptops that connect to the Internet via Wi-Fi. For this mode to work, you will need to organize an access point, this is done as follows:

1. Move to category Wifi and choose "Basic settings". In this window, the main thing is to make sure that the checkbox is checked "Enable Wireless", then you need to specify the name of your point and select the country. If necessary, set a limit on the maximum number of clients and a speed limit. When finished, click on "Apply".



2. Next, open the next section "Security Settings". Through it, the type of encryption is selected and a password for the network is set. Recommend to choose "WPA2-PSK", because it is currently the most secure type of encryption.



3. In the tab "MAC filter" rules are selected for each device. That is, you can restrict access to the created point to any equipment present. To get started, enable this mode and click on "Add".



4. Select the MAC address of the saved device from the pop-up list, and also give it a name so as not to get confused if the list of added devices is large. After that check the box "Turn on" and click on "Apply". Repeat this procedure with all necessary equipment.



5. The D-Link DSL-2640U router supports the WPS function. It allows you to quickly and securely connect to your wireless hotspot. In the corresponding menu on the left in the category Wifi activate this mode by marking with a marker "Enable WPS". You will find detailed information regarding the function mentioned above in our other article at the link below.



6. The last thing I would like to note when configuring Wi-Fi - "List Wi-Fi Clients". This window displays all connected devices. You can update it and disconnect any of the present clients.

Additional settings

Let's wrap up the main adjustment process by looking at a few important items from the Extras category. Many users will need to edit these settings:

Security Settings

We have completed the basic configuration above, now you can log in to the network using a wired connection or your own wireless access point. However, another important point is the security of the system, and its basic rules can be edited.

1. Via category "Firewall" go to section "IP Filters". Here you can restrict access to the system to certain addresses. To add a new rule, click on the appropriate button.



2. In the form that opens, leave the main settings unchanged if you do not need to individually set certain values, and in the section "IP addresses" type a single address or a range of them, similar actions are also performed with ports. When finished, click on "Apply".



3. Next, move to "Virtual Servers". Through this menu, ports are forwarded; to set the basic parameters, click on the button "Add".



4. Fill out the form according to your requests and save your changes. You will find detailed instructions on the topic of opening ports on D-Link routers in our other material at the link below.



5. The last item in this category is "MAC filter". This function is almost identical to the one that we considered when setting up a wireless network, only here the restriction is set for a specific device for the entire system. Click on the button "Add" to open the edit form.



6. In it, you only need to register the address or select it from the list of previously connected ones, as well as set the action "Allow" or "Forbid".



7. One of the security settings is configured through the category "The control". Open the menu here "URL filter", activate the feature and set a policy for it to allow or block the specified addresses.



8. Next, we are interested in the section "URLs" where they are added.



9. In the free line, specify a link to the site that you want to block, or, conversely, allow access to it. Repeat this procedure with all the necessary links, then click on "Apply".

Completing the setup

The procedure for configuring the D-Link DSL-2640U router under Rostelecom is coming to an end, there are only three final steps left:

Today we tried to tell in the most detailed way about setting up the D-Link DSL-2640U router for the Rostelecom provider. We hope our instructions helped you to cope with the task without any difficulties.
