I have issues with my wifi connection on ubuntu 20.04. It disconnects randomly only with my home wifi. I'm kinda getting mad after this issue, thus I am trying to monitor everything I can in order to find possible causes to this issue.
I ran sudo dmesg and I found at the very beginnig of which seems a log of my connection activities, the following message:
BIOS contains WGDS but no WRDS.
Can anyone explain me what is it? Can it be related to the connection issues I am facing? I don't even know what WGDS and WRDS are.

Example of output of sudo dmesg | grep WRDS:
[ 4.803894] iwlwifi 0000:52:00.0: BIOS contains WGDS but no WRDS
[ 3323.493255] iwlwifi 0000:52:00.0: BIOS contains WGDS but no WRDS
[ 4427.419793] iwlwifi 0000:52:00.0: BIOS contains WGDS but no WRDS
This message is related to information stored in the BIOS about the wifi device; It seems that WGDS and WRDS are related to geolocation and radio transmission power limitations.
The message sometimes appear during boot or, in some cases upon coming back from a sleep state, depending on the BIOS implementation. source
