sometimes (let's say 20 percent) when I try to connect to wifi (either at home or at the university), the connecting gets stuck in configuring interface. Only solution is to disable and enable wireless, usually it works after that (sometimes I need to do it two times). At home I use wpa2, at the university I connect to Eduroam where I use my university credentials.
This is what I use:
Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)
Is there any solution? To disable and enable wireless usually works but it's not very comfortable.
