Hello, we have 4 Dell Laptops with an Intel Wireless 7260 but we are
experiencing problems with the iwlwifi firmware.
The problem is that If our WiFi goes down (or we need to restart the
router) after the router is back up the connection could not be
established again.
In the dmesg line: "[ 167.863245] iwlwifi 0000:02:00.0: RF_KILL bit
toggled to disable radio." is produced when we try to stop/start
the adapter via its hardware button or the button in NetworkManager.
Hope this helps to solve the issue for everyone.
Again I have 4 machines with this issue so I can also test different
stuff on Debian 8 Jessie & Ubuntu 14.04!
Thanks,
Borislav.
