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.

..... Rest snipped .....
The D630, and possibly the OP's laptop are old. On windows systems, there is (was) a configure menu that turned off power management of the wifi, so that the wifi would always remain on. On Linux, you can disable power management by running iwconfig <interface-name> power off
Yeah ... I know .. it sounds as if you want to power it off. That is not the meaning of it. It turns off power management, so it will always be ON.

FWIW, I do not even have to use iwconfig to prevent my wifi : (02:00.0 Network controller: Broadcom Corporation BCM43224 802.11a/b/g/n (rev 01) from shutting down. So, I conjecture that it's firmware has power management off by default.

It seems that "Power Management" is already set to "off."

It seems that "Power Management" is already set to "off."
I am not sure that it is already set to off. Operation not supported is an issue in the drivers, such as brcmsmac cfg80211 bcma wext
wext is the wireless extensions driver.
On my machine, also not supported. To wit: # iwconfig wlp2s0 power off Error for wireless request "Set Power Management" (8B2C) : SET failed on device wlp2s0 ; Operation not supported.
So it is primarily a driver issue, or it is a device firmware issue. Sometimes if the device itself does not provide for a command to turn power management off, then the driver itself will not support such a command.
You might want to ask the linux wireless mailing list at linux-wireless@vger.kernel.org
Of course, you must subscribe first.
