Topic: Asus 500gP with TP-Link TL-WN660G - weak signal

The content of this topic has been archived on 5 May 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

Hi everybody!

I have a Asus WL500g Premium and I replaced the internal broadcom miniPCI card with the TP-Link card TL-WN660G. When I was using White Russian the card was working properly but since I'm using Kamikaze the signal strength got really weak. The maximum distance is about 10 meters from the router.

Does anyone know a solution? Maybe use the old driver which was used in White Russian. Or could it just be a configuration problem?

Thanks

Alex

Try with PRE-7.09 and Kernel 2.4.

Kernel 2.6 is unstable and sucks in many ways (this is what I have figured out so far)...

just to add to that (I have a 500Gp as well), if you want to use kamikaze and 2.6 use 7.06 it has the last known good kernel in it, the other have 2.6.22  - which causes random segfaults.

What I do is use the kernel bits from 7.06 and the package bit from 7.07,9 or trunk.

Hi guys!

Thank you for your tips. Sorry for taking so long to respond.. I have tried 7.06 before but with the same result: I only got a weak wireless signal.

@forum2006: today i flashed your image with the madwifi version included it was the same result. Only when I used White Russian the signal was normal. So I idea was to use PRE-7.09 with Kernel 2.4 and the madwifi version from White Russian.

Could this work?

Thanks

Alex
