Title:
wifi network keeps disconnecting
Status in linux package in Ubuntu:
Incomplete
Bug description:
I'm running Ubuntu 20.04 with the latest updates on a Thinkpad X220.
Since about a week I keep having network disconnects. I am using an
Intel Corporation Centrino Advanced-N 6205 wifi chip. Before it's been
working great.
There seem to be others with this recent problem.
