Intel 7260 Wifi not working on Ubuntu 15.10
Status in linux package in Ubuntu:
Incomplete
Bug description:
I'm unable to use my Intel 7260 Wifi card on a clean Ubuntu 15.10
install. It is able to connect to my wifi network but after a few
seconds the connection stop working. The same card on the same
notebook used to work without problems on Ubuntu 15.04. I'm sending
below the output of lspci and dmesg.
