Top 20 games played on Steam Deck in the past month, sorted by playtime.
It’s probably a result of wireless interference somewhere between the deck and the desktop. I also had a really bad experience with remote play and sunlight/moonlight before I hardwired my desktop to the router via an Ethernet cable. Just making that one part of the chain wired completely solved my issues.
Yeah OSI model says to check the connection between access point and deck. I remember back when I used the Steam Link to stream to my living room from my wireless desktop I would actually get better performance if the Steam Link was wireless point blank from the access point than if it was connected via Ethernet.
