Public bug reported:

I've noticed since a recent kernel update that my XPS 15 running Ubuntu
14.04 keeps dropping my 5ghz wifi connection and subsequently that
connection s not available from the drop-down list in the network
manager applet, only the 2.4ghz connections are.

The wifi card is an Intel AC 7260 and I see there have been other bug
reports about problems with the latest driver
(https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1293569)

Possibly a duplicate but wanted to register this independently first, in
case not.
