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
All I can suggest is that the firmware of that wifi has power saving function that turns it off after what it decides to be a period of inactivity.
Another thing to check is
System -> Preferences -> Look and Feel -> Screen Saver
From that gui, click on Power Management Be sure to check all 4 tabs of the Power Management Gui.
R U running on battery most of the time?
I would like to echo the problem that Henrik is having.
The Wifi on my Dell Laptop (D630) has been dropping ever since I installed Fedora on it (initially F18; now F21). No matter which Fedora version, the Wifi connection eventually drops, can be restored a few times w/ systemctl restart NetworkManager
and then eventually drops.
I too would like to find a way of restoring and maintaining the Wifi connection w/o rebooting.
Once, I can't connect I pull out an ethernet cable and connect from the built-in LAN port to a switch. No problem. Ever.
The Wifi chipset is Broadcom; I generally run with the power suplly plugged in.

Apologies for the verbosity; but it's in the interest of diagnosing the problem and finding a solution.
Much thanks,
