Hello .
I'am having problem with my broadcom wireless adapter which is that when im trying to connect to a network using wicd the computer will be lagged for about 2 minutes then it tells me bad password ( after trying to validating authentication ) .

and also when i try to use command etc/init.d/networking (start/stop) its the same problem.

by the way when im using eth0 (wired connection) it works perfectly so the only problem with wireless.

Thanks for reading, i hope you help me.

extra info..
when use lspci | grep Broadcom i get this data
