Anyone else having issues with their OLED not connecting to the internet during set up??? I’m so sad. Tried everything to troubleshoot my internet. No other devices connected are having issues either. Narrowed it down to the Steam deck itself having issues. :(
As others have said turn off the 160MHz band on the router, there is obviously a driver issue (same as intel chipsets had when WiFi 6 came out).
Unless you live in a place with very little chance of interference there is no need to have 160MHz band running. The speed benefits are usually negated to the point of where you actually have a worse experience due to it being so susceptible to interference.
I solved it and shared what worked for me since the OLEDs are having a weird issue. Thanks tho!
