Only a reboot will do. When I was running 3.16.0-4-amd64 from Debian/stable, I https://answers.launchpad.net/ubuntu/+source/gnome-nettool/+question/221076 noticed the following message, but only _once_ and Wifi worked fine even with that message: iwlwifi 0000:04:00.0: Error sending REPLY_TX_LINK_QUALITY_CMD: time out after 2000ms. iwlwifi 0000:04:00.0: Current CMD queue read_ptr 25 write_ptr 26 iwlwifi 0000:04:00.0: Loaded firmware version: 18.168.6.1 iwlwifi 0000:04:00.0: Microcode SW error detected.

It appears that applications (e.g. Firefox) are hanging while loading something, then they fail and GNOME pop-up an error message telling that no wifi connections are available. Disabling/Re-enabling the wifi solves the issue until the next fail... I recall it already appeared on Fedora 19, but it was waaay less frequent.
