[pkg-wpa-devel] Bug#594561: firmware-ralink: fails to detect APs at frequency 2.472GHz

[Wenceslao González-Viñas]

Hello,

to tell you the truth I was scared at looking at the 
http://thread.gmane.org/gmane.linux.debian.devel.kernel/54624/ . The 
reason is that probably you are right, but unfortunately I am no such an 
expert to get a solution from the thread.

I am looking in the packages repositories of debian an I am not able to 
find crda. On the other hand in the package contents search the 80211 
stuff is related to linux headers, which I have installed. One thing 
that might help is that when I used iw list before, I got something like 
nl80211 not found. After that, I thought that one module should be 
loaded. I loaded mac80211. I checked it was (and I got mac.... and 
cfg....). Now, when I type iw list, I got nothing (neither error nor 
result).

Everything and what you told me makes me feel that the solution is 
nearby and easy; but I don't know how to go on ...

Thanks a lot,

Wenceslao
