driver cannot associate, why?

Following bug 994255, in precise I installed mainline kernel 3.4.0-030400rc6-generic followed by the deb in post 2 of referred bug which correctly installed wl. However, as I restart the pc it doesn't connect to the router.

I can't really understand the problem. The WPA key is correct, but it still doesn't connect. lsmod shows:
wl 2573568 16892616544235766756 [permanent]

I would try to remove and install the driver again but doing:
pmatos@jupiter:~$ sudo rmmod wl
ERROR: Module wl is in use by [permanent]

Any idea of might be wrong or how I can obtain more information to get to the bottom of this issue?
