view story

http://askubuntu.com – I have Ubuntu 12.04 using Broadcom BCM4313 and can't get it to successfully connect to my wifi. I'm sure the problem is not with my wifi since other devices are able to connect. It detects networks but whenever I try to connect, I only get "Connection Failed". I checked my drivers, modules and blacklist but I'm not sure if there is something I'm missing. Do you have any idea what could be wrong? I attach some information about my network card hopping it's of any help: $ lspci -vv ... 01:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01) Su (HowTos)
