WiFi restoration

[Timothy Murphy]

One room in my house is at the boundary of WiFi reception,
and WiFi occasionally fails there.
When this happens it is nearly always restored by re-booting.
Re-starting NetworkManager never does the trick, however.
Is there any other step I could take, short of re-booting?
I'm running Fedora-21/KDE.
