I have just installed Ubuntu 13.10 on my Toshiba Satellite Pro L650. After several reboots, installing/ uninstalling the broadcom driver I still can't connect. It detects the wi fi signals and the icon flashes as if it's trying to connect but never actually does. I'm really quite rubbish with code and stuff, but I really like Ubuntu as an OS and would really appreciate any suggestions anyone can offer! 02:00.0 Ethernet controller: Qualcomm Atheros AR8151 v1.0 Gigabit Ethernet (rev c0) 03:00.0 Network controller: Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter (rev 01)
