I've done this several times over the last 18 years or so. The most recent was a few months a go. And my steamdeck persuaded me. Unfortunately I ran into the same WiFi networking issue I've never managed to resolve. Even on different hardware. Pings to my default gateway are ridiculously slow compared to windows. I spent countless hours trying to resolve. I gave up and have gone with windows 11 ltsc.
This is the type of thing that AI is actually good at diagnosing in my experience. Haven't had anything similar happen but seems more of a router issue upstream.
Maybe worth checking what Steam Deck's connection has configured differently given it's on the same network?
That is a very good point, what on earth was I thinking, I didn't try pinging it from my steamdeck. Actually, I'll try that, but now I'm back on windows the ship has sailed.
Good point about AI too.
This is on mint Linux and unless I'm remembering wrong years ago it was mint Linux that had the same issue completely different hardware and network
Interesting; I haven't had wi-fi issues in Linux for more than a decade, but admittedly I sort of selection-bias towards laptops that are known to work fine with Linux.
