Step-by-step setup of the d-link 2640u router

After the user configures the D Link DSL 2640U, he receives full and fairly fast access to the Internet.

Moreover, among the additional tasks of the router is the distribution of received data using a wired and wireless connection.

The third is the provision of television using IPTV technology.

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

Connecting a modem

In this section we will look at how to connect a modem to a computer.

First of all, the router should be connected to power - insert the end of the wire from the power supply into the corresponding socket on the back of the modem, and the power supply itself into the outlet.

On the back side of your modem (router) there are 4 LAN inputs at once. It is there that insert one of the ends of the blue wire that comes with the D-LINK 2640U, and insert the other end into the LAN port on your PCM.

At the same time, be careful: the LAN light on your router should light up with the number of the modem port into which you inserted the local wire. In this case, both ends of the wire must be in place (port on the PC and port on the router).

After this, go to the next tab of the instructions, where you will be asked to connect your modem and splitter. There is one more cable included with the modem - insert it into your splitter (separator), and place the other end of this cable into the corresponding port of your router - “LINE”.

Grouping of ports.

For IPTV to work, you also need to allocate a separate LAN port for the TV set-top box and combine it into one group with a PVC connection. To do this, in the advanced settings, select the “Advanced” => “Port Grouping” section:

By default, all ports and WAN connections are in the same logical group:

Click the “Add group” button. We get this window:

In the Name field, enter the name of the group - iptv, for example. Below, using the arrows, we move one of the LAN ports from the left field to the right. The same goes for the WAN connection: move the TV connection to the right. Click the Save button. In the grouping of interfaces we get two groups:

Click the Save button.

Factory settings

Each device has its own “factory settings”. We will talk further about how to reset the D-LINK 2640U to factory settings. You have to reset the settings to factory settings if you simply cannot go to the modem settings menu, or the modem was configured incorrectly.

The “RESET” function is available on every router and using it is much easier than you think:

find a needle or awl at home, look at the back panel of your router, where you will see a small hole labeled with the word “RESET”;
this is it: insert a needle (match) there, wait about 5-6 seconds. In this case, the router must be turned on;
After this time, all the lights on the router will go out one by one. It may restart, which means that the modem settings have been reset to factory settings. Now you know how to reset D-LINK 2640U.

Firmware update

In this section we will tell you how to properly update the firmware of your router. After purchasing each device, we advise you to check for the latest firmware (updates), which will ensure trouble-free operation for a longer period of time.

First of all, you need to determine such a characteristic as the hardware revision of the modem. Look on your router (usually on the bottom cover) for a label with a few lines written on it. Among these lines, find the one signed with the letters “H/WVer”. This is what you need;
after that there will be only two characters - a letter and a number. For example, A1. This is a hardware revision;
let it be C4.
then go to the D-Link FTP server and look for the firmware you need in accordance with the details;
after that, check whether your router is connected to your PC or laptop. Open any browser, enter the network address 192.168.1.1 in the browser window, enter your username and password (by default, in the factory settings, both are the word admin). Click on the “Login” button;
go to the “Manual Settings” tab, from there to the “System – Software Update” section and click on “Browse”;
select the firmware file you downloaded and click on the “Update” command;
Do not turn off the power to your computer and router. Wait until the modem update is completed;
This completes the D-Link 2640U firmware update.

Possible malfunctions and ways to eliminate them

Modems for Rostelecom: features and configuration

If your DSL router has problems, the first thing you should try is to reboot the device. Another option is to reset the settings to factory settings. How to do this is described below.

It is also worth remembering that cables can also be damaged. It is worth carefully checking all connections on the equipment and devices connected to it. Sometimes situations arise when the problem is on the side of the Internet service provider. Then you should call technical support and get expert advice.

If the DSL router still does not work, it is recommended to contact a service center. Our technicians will diagnose the problem and help you solve it.

Firmware update

Equipment becomes obsolete over time. In order for it to last longer, it is periodically “stitched”. The manufacturer posts the latest updates on the official website. For the 2640u model they are downloaded from:

https://www.dlink.ru/ru/faq/370/935.html

The last update dates back to 2013. This means that this device is no longer supported by the manufacturer. Let's look at how you can update your DSL modem.

Via web interface

Via the “System” menu, “Software Update” item:

There are two update options in the window.

First: specify the downloaded file manually, click “Update”:
Second option: automatic mode. The DSL router will automatically connect to the update server and perform the necessary operation:

The current example uses a 2640u network device Wi-Fi dsl emulator, so the screen displays the message: “Unable to check for a software update.”

Via mobile application

There is also an update option via the mobile application. It exists for Android and iOS platforms.

Android link: https://play.google.com/store/apps/details?id=ru.dlink.drcu&hl=ru.

Link to iOS: https://apps.apple.com/ru/app/d-link-assistant/id1342564878.

Unfortunately, the 2640U is not currently on the list of compatible devices. Accordingly, the user does not have the opportunity to perform this operation through the mobile application. The list is constantly updated and its status can be monitored in the application store.

Resetting the router to factory settings

There are two ways to perform a reset on the DSL 2640U device. In the first case, just press the Reset button on the back side, holding it for 10-15 seconds. Resetting all LEDs at the same time will indicate that the process is complete.

The second option is through the web interface. To do this, select “System” in the upper left corner, then “Factory settings”:

Within two minutes, the network DSL device will roll back to the factory configuration.

ADSL connection parameters

ADSL connection parameters are very important, because both the speed of your Internet connection and its uninterrupted operation will depend on them.

As described earlier, go to the web control panel of your modem:

Open your browser and enter 192.168.1.1 in the address bar. Enter your username and password (admin/admin by default) and click on the login button;
go to the “Network” tab, to the WAN section. If you just purchased the router, you should remove all connections. Use the “Delete” button to do this;
then click on the “Add” button and enter your Internet connection parameters;
and then follow the instructions below, because the ADSL connection parameters directly depend on your Internet provider.
