SubjectNot getting connection with BRCM 4313 (Linux 3.3 brcmsmac)
Date
Hi,

This is on a Samsung NP305U1A subnotebook.
This WiFi never worked under Linux, tried 3.2.x previously.

When attempting to use it through NetworkManager it shows the AP, then
keeps trying to connect, then prompts for the password again. Meanwhile
the kernel log shows the timeout.
Yes, I double checked the password.

iw dev wlan0 scan shows always at most one AP (although there should be
many visible), possibly the one with the highest rx signal:

Happy to debug this, building custom kernels for this will be no problem.
Thanks in advance, bij voorbaat dank, etc.
