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.
..... 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.
Much thanks for the reply; here are my results:

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