Seems like multiple people are having issues with Intel AX200 cards on Linux. There's plenty of stuff about it on the Internet, but there doesn't seem to be any well documented overarching resource about the problem.
AX201 cards are different! For now, don't include AX201 reports here. If we believe there's enough similarities regarldess of how vastly different these cards are, we'll extend reports to them, too.
We classify the following symptoms:
|stall5g||5GHz networks work for a while, but suddenly stall - no more packets can be sent/received until reconnect/powercycle.|
|bork5g||generic 5g breakage (connection drops, deassociations, other) which doesn't match the above specific categories|
|ok||Everything works fine.|
Please suffix unknowns with 'ish', and try to complete them with reliable data ASAP.
