I apologize for the offtopic, but there is nowhere to ask a question, maybe there will be experts. I have dsl-2540u, and also tp-link mr3220 router, it is required with dsl-2540u, to distribute the Internet by wi-fi through tp link, how to implement it?

[___phoenix___]

Freeon387, not so oak, chose to get an Internet with wan in tp link, but he does not get ip address :(

[___phoenix___]

Freeon387, in the screenshots you can see what exactly is happening

Freeon387, Dlink 192.168.1.1, at the expense of the second xs, and specifically what is required to be done?

On the D-Link DSL 2540U, you must enable DHCP on the LAN interfaces, and connect the tp-link mr3220 by wire to one ofLAN
In this scheme, tp-link mr3220 will work as an access point in a single common network without address filtering.

gri8341, already done, in a different way) thanks for the feedback!

[mirzayaky]

Tell me please.
Is it possible to connect the second router via lan to dsl2640?
What would be at the expense of the second router to expand the coverage area.
Maybe there is an article already someone tried to do so

[djgelius]

Can this modem be used as a router via a PPPoE connection and connected via the RJ-45 Internet?
I have the opportunity to sit through the fiber

There is a dsl-2650u router, but not the same as the cap in the photo, but suchhttp://www.dlink.ru/ru/products/3/1883.html. Is it possible to put on it OPENWRT or DD-WRT?

Hello, members of the forum. I had a problem with the router DSL_2640NRU, namely, the Internet connection in general is broken for 5 minutes and restored to one. A very narrow circle of people is connected to wi fi, I haven’t been indulging in heavy downloading lately, I called Rostelecom at the expense of the router and still could not fix it. What can cause such a spring exacerbation at the router?

called in Rostelecom

They need a very long time to prove. From the first time, they are always doing well. Then, after a week of daily calls, it turns out that there were problems on the line.
Ask your friends for a time modem and check. After that, you will already be confident in talking to them. Or let them come with your modem.

г‚Ї гѓћ,
DNSy can fall off. Usually, their default installers do not prescribe to either the Reuter or the client’s computer. Check it out. As an option, try to put on a computer Google 8,8,8,8
Try to ping such as tape. Ru or Yasha. py sites. Better, of course, a dedicated ip. Immediately it will be clear.
As an option for Rostelecom. Ping their server or ip. If they answer, and for example, Yasha.ru is not there, then the screen name mail and yell - where the Internet will be justified :)

There is a DSL-2640U rev B2 / DSL-2640U / BRU / C in the list of OPENWRT profiles. collected for DSL-2640U / BRU / C - is not installed on revision C4. wrong chip
and someone else has C4, I can’t say about other revisions, heats up on firmware 1.0.32 hellish, a radiator from nothing and is stuck on some snot

How to properly configure the IPoE to DSL-2640U H / W ver: D1 F / W: RU_1.00? I found the firmware version 1.16, I did not find the WAN assigned to the LAN. I'm trying to tune in to Ukrtelecom, since their new Tenda310 is still that ...
