    Past EOL and out of support maybe upgrade? – David Oct 03 '21 at 08:41
  • You may want to upgrade to 21.04. Also, have you seen [this question](https://askubuntu.com/q/1186106/1222991) and it’s answers? – matigo Oct 03 '21 at 08:48
  • Ubuntu 20.10 (along with all flavors) is *End-of-Life* and thus unsupported on this site (https://askubuntu.com/help/on-topic), and many other Ubuntu sites, unless your question is specific to moving to a supported release of Ubuntu. https://fridge.ubuntu.com/2021/07/25/ubuntu-20-10-groovy-gorilla-end-of-life-reached-on-july-22-2021/ https://help.ubuntu.com/community/EOLUpgrades – guiverc Oct 03 '21 at 11:02
  • Ubuntu 20.10 is the 2020-October (ie. a *year.month* format is used for releases) release of Ubuntu; it was not a LTS (*long-term-support*) release meaning it had 9 months of support, upgrading to the next release (21.04 or 2021-April release). Oct+9 months =2021.July for EOL. The kernel 5.8 is no longer *patched* for security-flaws (it's EOL) so be careful online (ie. *release-upgrade* asap) and consider a LTS release if you don't want to *release-upgrade* every 6-9 months as required for non-LTS releases. – guiverc Oct 03 '21 at 11:05
  • Thank you! I was not aware of 20.10. reached it's end of life. I've updated to 20.10 and kernel 5.11. I've tried the backwards iwlwifi $ sudo apt update $ sudo apt install backport-iwlwifi-dkms and a "power drain". Still, the problem persists. Any ideas on where to start? – Andreas Burger Oct 05 '21 at 08:20
