I have Ubuntu 12.04 on a Lenovo G580 with Atheros AR8162 Ethernet and Broadcom BCM4313 Wireless Driver.
I try the this:
How do I get an Atheros AR8162 working?
but it doesn't work.
When I type make install it comes:
FATAL: Could not open /lib/modules/3.2.0-29.generic-pae/modules.dep.temp for wirting: Permission denied make *** [unistall] Error 1
Edit: 05.02.2012
After I try it with sudo (thx to maggotbrain) cablebased network works. I update my system and install the Broadcom-STA-WLAN-Driver.
Restart and after my reboot cablebased network doesn't work anymore and I can see wlan's but I can't connect.
