Connecting the phone cable through a splitter to the modem.
Choose the type of connection, in my case PPPoE. it requires a username and password. It is used to connect via Ethernet or DSL.
As I live in Kazakhstan and our ISP is Megaline, I know my ISP settings for Internet connection.
Settings in each region may be different, for details I recommend to contact your Internet provider.

The connection is not completed, confirm the action on 192.168.1.1.
Check if the internet is available via ping and ya.ru.
If it was successful, the host will be accessible and the corresponding window will appear on your screen.
If there is no internet, after a few minutes click the double check button. Everything should work, if you have connected the modem correctly and have entered valid authorization data and the network configuration data for your region.
Then go to the System tab and select Save and Restart.

This process usually takes 2 to 4 minutes.
Wait until the modem has rebooted, open any page, for example, and enjoy the Internet.
To configure Wi-Fi router D-Link DSL-2640U choose the Wi-Fi tab on the main page of the web interface.
You will see a window with a menu of three items. Go to “Main settings” and enter the name of the wireless network, which will be displayed on the gadgets when searching for an active network (SSID field), in the “Channel” select the most unloaded channel or leave the “Auto”. Here you can also tick the “Isolation of clients” option or create a guest network by specifying its name.
Go to “Security settings” and set network password (do not touch the field “Network authentication”). Leave the rest of the parameters set by default.
The MAC-filter menu item is used to control access to your Wi-Fi network at the client device level: you can allow access only to specific devices with specified MAC-addresses or specify a list of those gadgets that are not allowed to connect to the network.
The manufacturer regularly releases software updates that make the characteristics of D-Link DSL 2600u better, and the device is more stable and productive. Flashing of this router is only possible with a cable connection. The procedure is as follows:
- download the latest firmware from the official D-Link website;
- In the interface of the device find the Update Software item of the Management section;
- Specify the location where the downloaded firmware file was placed (press the “Browse” button and enter the path”);
- Start the update process by clicking on the “Update” button.
The update takes a couple of minutes, after which the router will reboot. Specialists recommend that after such an update to return the device to its original settings. Go to Management, then select Settings and look for Restore Defaults. Having returned to the default settings the device will have to be reconfigured.
In this section we will tell you how to update the firmware of your router. After purchasing each device, we advise you to check for fresh firmware (updates) to ensure trouble-free operation for a longer period of time.
first of all you need to define such characteristic as modem hardware revision. Look for a label on your router (usually on the bottom cover) that says a few lines. Among these lines find the one signed with the letters “H/WVer”. That is exactly what you need;
Modem setup in bridge mode
The D-Link DSL 2540u can be used as an additional router (connect it to another, more powerful router). To connect two devices, use bridge mode:
- Open the window with Modem Setup Wizard. Uncheck the option DSL Auto-connect and in the box that appears, enter the VPI and VCI values depending on your provider (ask tech support). Click on Next.
- In the next Connection Type window choose Bridging, Encapsulation Mode. LLC/SNAP Bridging and click on Next.
Check box and set name for service
Rostelecom uses PPPoE in most places to connect to the Internet, so we will consider setting up exactly on its basis. In old and new firmware version settings items are located slightly differently, so here is a description for each variant separately.
In the main menu select “Network”, “Connections” and press add button. On the screen that appears, set the following parameters:
- “Connection type”. Here you have to choose the PPPoE mode. This allows D-link DSL-2640U to work as a router.
- VPI and VCI. These parameters are different for every region. You can clarify them by calling technical support on the toll-free number or by finding the appropriate table on the web.
- Write the user name and password for access. You can find out these data from the documents, which were obtained during the connection. Important! Password must be confirmed in the next field.
- Service name. In this point specify the name for the connection, which will allow you to define it, for example, “Internet.
- Additional parameters. It is obligatory for normal functioning to tick the items “Keep Alive” and “IGMP”.
If the line for trimmer leaves much to be desired and frequent connection failures are possible, it is better to specify the actions at unsuccessful authorization attempt. In the “LCP gaps” field, specify a value of 2, and in the “LCP interval”. 15. This will allow the device to first try to connect twice, and then pause for 15 seconds.
The sequence of actions in the new firmware is slightly different. After entering the interface, the user sees on the main page several buttons and information about the device and the status of ADSL.
The first thing to do to configure the Internet is to go to the advanced control mode. The button is located at the bottom of the screen.
In the section “Network” select the item “WAN”. A window will open with the available connections. If it is not empty, then before configuring it, you must delete all connections, to do this, click on them in sequence with the mouse and select “Delete” in the lower right corner of the screen.
Press “New” button in WAN interfaces and set up.
In the window that appears it is necessary to specify the standard parameters, namely:
- Connection type. PPPoE. This is what Rostelecom uses for all subscribers connected via ADSL technology.
- “Intease”. DSL (new). Otherwise you will not be able to set VPI and VCI.
- VPI and VCI. These two parameters can be obtained from the technical support.
At this point the Internet settings are complete. If you don’t need to connect an IP TV set-top box, you can save the settings by reloading the DSL-2640U. To do so we find the “System” menu at the top right of the D-link logo and choose the appropriate action.
Possible problems with the router and their solutions
The DSL-2640U modem router is an entry level device that is positioned for home use. The modem usage as a LAN router-switchboard will overload its processor, which will result in performance degradation and possible problems like suspension, intermittent WI-FI switching off or even premature failure.
For a long time I had to use DSL-2640U as a router in a small office. Four computers plus two network printers and the clients’ smartphones put an excessive load on it: the modem was overheating and hanging, and every hour or an hour and a half I had to turn it off. The bosses did not want to install a new router. they were thrifty capitalists. I had to cut a round hole in the top cover of the modem and install a cooling fan from a faulty motherboard. Thermal mode came back to normal, the router was able to work without any failures during the whole working day.
Table: typical malfunctions of DSL-2640U and troubleshooting
|Problem symptom||The reason is||How to fix|
|Indicator light is not on.||Power supply unit is defective.||Replace the power adapter with defective one. Any PSU with 12v voltage and current of 0.5A and above will do.|
|Indicator light is orange.||Modem is in the emergency recovery mode.||Modem firmware is damaged. Load new firmware with patch cord, as described in manual.|

|The modem is getting hot, the speed of network access is falling||Load on the modem processor is too high.||If you have no possibility to decrease the number of connected clients, put the modem in bridge mode and use it together with standard router.|
The D-LINK 2640U Modem Router is a balanced and affordable solution for ADSL Internet access. If you don’t have enough speed of Internet, and the main thing. you need equally high speed of both download and upload. you should think about switching to another provider, which provides services via twisted pair or optical channel. Buying a more powerful ADSL router only makes sense if you need to create a home network with a large number of devices.
