Fedora 20: dropping wifi

[Henrik Frisk]

Hi,

I've been having this problem for some time now, on and off. I loose WiFi
and there are no available networks to connect to although I know there
should be several and other devices are connected. The only remedy is a
restart. Logout will not help. After restart I can access networks for a
while after which it is dropped again.

My Network controller is Broadcom Corporation BCM4331 802.11a/b/g/n (rev 02)

Any suggestions?

Best,
/Henrik
