I am dual-booting my laptop going between Windows 7 and Ubuntu 12.04 LTS. Initially, I can connect to WiFi, but if I get disconnected for some reason, or if I restart my router, Ubuntu won't reconnect unless I reboot my laptop. Just logging out and back in won't work, I have to restart ubuntu, why and how can I fix this?
The output of sudo lshw -c network

I have installed Broadcom STA wireless driver. I have experienced the same issue before with other distros; Crunchbang doesn't connect to wireless at all, Archbang won't connect to wireless after upgrading pacman. The problem began with Ubuntu, which is why I tried both Crunchbang and Arch and then ended back at Ubuntu.
