How do I get my Broadcom BCM4313 working correctly?
*My Ubuntu 12.04 LTS does not detect any wireless network unless I reboot with the ethernet connected. With ethernet connection, both the WiFi and ethernet are detected and, even if I remove the cable, WiFi keeps working. However, each time, I am having to boot my laptop with the LAN connected to be able to use WLAN.
Here is my hardware configuration. Well I posted this post about a day ago and today , I just uninstalled all the broadcom drivers etc ... and there without any drivers installed the wireless runs perfectly !!!
What's that all about?
