Hi,

Does the TL-WR841ND v7 support the same type of "repeater mode" as the TL-WR840N v6 or does the TL-WR841ND v7 actually support "WDS"? WDS is known to have compatibility issues.

Could you perhaps post a screenshot that shows the available repeater options that you see on the TL-WR841ND v7?

The old 841nd support wds and have old software

The wr840 does support new 2022 software and quick setting in router has repeater mode added

Ok, I see.

So, that must be the reason why the TL-WR841ND v7 behaves different than the TL-WR840N v6.

Even though WDS and "Range Extender mode" serve similar purposes, they are not the same thing.

For WDS to work both ends have to support it. In your case it looks like the Wi-Fi router (the one that's 25m away) you are trying to connect to either doesn't support WDS at all or doesn't support it properly and that's why you get no working connection.

The "Range Extender" mode of the TL-WR840N v6 works differently and doesn't require special support from the Wi-Fi network it is connecting to.

I want to solve the problem, how can I solve it, I tried to connecto to 2 different networks one tplink router and the other is huawei echolife vdsl router 

and both n300 2.4gh 

  @zageng 

To solve the problem you would have to replace the TL-WR841ND v7 with another device that has a regular "Range Extender" mode that works in combination with any Wi-Fi router.

  @woozle 

replace what sir it is old version no warranty

I want to connect this one it works fine with near networks

  @zageng 

Do you mean if you reduce the distance between the TL-WR841ND v7 and the Huawei Echolife, then you can successully establish a network connection?

Well, if that was the case, then you need to place the TL-WR841ND v7 at a location that is nearer to the Huawei router. There is nothing else that could be done.

  @zageng 

is there anyway to fix that with a software or modified software

  @zageng 

Do you mean increase the wireless range of the router? That cannot be changed by software.

  @woozle 

i didn't say increase wireless range, I mean when i connect to a nearby network with good signal my router works as a repeater, in fact when i do that it doesn't work it gives me no connection

the network is near and when i do connect using wds it doesn't give me a working internet connection
