I got a problem with my Lenovo G580 (Broadcom 4313) and Linux.
On Windows I can see about 10 different wifis in my room.
On Linux I dont see any. When I'm sitting directly next to my router I have about 50% signal quality but at least it works with +10mb/s.
When I'm moving away I still can see my wifi with 30%+ but he has problems on connecting. He says he's connecting for 10 seconds and then I get an error, that I've been disconnected. After 4 or 5 metres I can't see it anymore.
The driver (bcma) seems to work but the signal quality is really bad, like if the networks card is restricted to 10% of the power or something like that...
I've read, that the proprietary driver from broadcom seems to work fine for the 4313, so I checked it out.
I've already read (In the ubuntu wiki), that I have to deactivate bcma and two different drivers and I did it as described in the wiki. But the sta-driver still seems to have a conflict with a driver, so it doesn't start.
Does anybody know, what I still can do, either get bcma to work fine or get the sta-driver to work? And yes, I already tryed google...
I'm still relatively new to Linux, so plz be tolerant ^.^
PS: Sorry for my bad english
