(SOLVED) wifi problems

Hi everyone. So, I have a problem.
General wifi signal inestability and whenever there more than 1 laptops on my network my connection drops and theirs goes well...
Something weird:
lspci | grep -i wireless
returns nothing (allthough I AM connected to my wifi and it is working)
WICD gives me a unable to connect: bad password (The password is not the problem) and I usually have to wait and try latter.

Any ideas? Might it be a problem with the driver? If so, I read somewhere that compiling the realtek driver should help, how do I know which one should I compile and how do I tell the kernel to load that instead of the default one?

My wireless card is not a USB!!!
I don't understand...

Re: (SOLVED) wifi problems

Why not? It could be connected to the internally to the USB bus. The Realtek site also says that it is USB 2.0. It seems that the support for this chip is broken in newer kernels. You could try the 2.6.31 kernel. You can grab the package from the ARM: http://arm.konnichi.com/core/os/i686/ke … pkg.tar.gz

Install it with:

pacman -U kernel26-2.6.31.6-1-i686.pkg.tar.gz

Maybe this helps?

Re: (SOLVED) wifi problems

Ok, i'll give it a try and report back!
Thanks for your help!

So... it is definitively a Kernel issue? Not a configuration or hardware issue?

Re: (SOLVED) wifi problems

It should be fairly obvious what dmesg is reporting to you but since you asked I'll sum it up as best I can.

Your wifi card IS getting a response from the router, it's associating (connecting) then, for some weird reason the connection just dies when the router receives no further responses from the card. It then re-tries to re-associate and so forth, ad infinitum. For whatever reason, your wifi card is incapable (?) of responding to requests from the router for new packets. I'd say the driver for this card is, as another poster said, very seriously broken.

Re: (SOLVED) wifi problems

I did understand that! I was asking what might be causing it! So... it's a driver issue and i'm screwed?

Re: (SOLVED) wifi problems

Have you looked elsewhere on the net ? I did a quick search and came up with another thread but it doesn't solve your issue.

http://www.linuxquestions.org/questions … ss-796917/

My suggestion is buy a decent little usb dongle wifi connector and use that instead. I use a DWA-160A (Rev. A). The Rev. A is important in that this one uses an atheros chip which is well supported on linux. The other revision, "B", uses an ralink chip that seems problematic in linux.

Re: (SOLVED) wifi problems

Yes...
That seems far worse than my problem.
The USB thing is not much of a good solution :S
I guess I'll have to live with it and hope for the kernel devs to improve it in the future...
Anybody knows if they have in their schedule or if it's being worked on?

Re: (SOLVED) wifi problems

E-mail the upstream devs is the best idea if you want to know the status of this driver.

Re: (SOLVED) wifi problems

The rtl8187 card isn't working very well under linux. If you don't want an usb dongle, you should get a mini-PCI card with an atheros or any other supported hipset for a few bucks. I would buy another card instead of trying cuntless hours to get the realtek card working.
