Public bug reported:

When I disconnect my AC adapter or run `sudo tlp bat` to switch to
battery mode my wifi stops working. Reconnecting the AC adapter or
running `sudo tlp ac` returns the wifi adapter to a functioning state.

I use the default TLP configuration without modifications and at first I
was thinking that this is a bug in TLP. The FAQs already have an entry
about this and state that this is due to the "kernel driver does not
implement power saving properly" [1]. This is why I'm reporting the
issue here.

I'm using Ubuntu Disco and I remember this working in previous Ubuntu
versions / kernels. This happened on kernel 5.0.0-15-generic but also on
the 5.1.5-050105-generic mainline kernel.

Below is a snippet of /var/log/syslog at the moment of switching TLP to
battery mode. Battery mode was activated at 11:25 and AC mode was re-
activated around 11:27.

Please let me know if this is actually the right place to submit this
bug report and whether I can provide more information.
