High Ping

I have been noticing pings about 100-300+ ms with almost nothing running. Normally I have xonotic and nextcloud running with nothing else in memory BUT I have turned off and DISABLED both of them for diagnostic purposes and the results below are with them both off.

Not sure I understand the setup but this is only between machines? What about pinging the router/firewall/whatever?
If it’s wifi there might be interference from other access points maybe but that should change if you move?

2 out of 3 boxes are ok, one is wired, other is wireless. The 3rd box is wireless 5 ghz and seeing high pings.

I’d try 2.4GHz to see if there’s a difference. I’ve got the same card in a china laptop and I’ve seen multiple issues with it when searching for answers. I got mine working well on 2.4GHz and then forgot about it since I just assumed my access point and and that card didn’t play well with each other.
It didn’t work at all on 5GHz on an older kernel (I think it was Ubuntu) but worked well on Arch. That was like 6+ months ago though so I guess that might have been solved.

Error messages in dmesg might also reveal something that might help you.

already tried that too :frowning:
