Bug Description

On a fairly clean 17.10 install, on a Thinkpad T450, the wireless connection keeps dropping. Other devices nearby do not suffer the same way.

I can turn the wifi off and on again to get reconnected. It happens multiple times over a short period of an hour or so. So quite irritating.
