Can the WiFi card be disabled in BIOS? If so, try that and see how it reacts?

Are you running Stable, Beta or Preview ?

I’ve given up on using the Steam Deck without wifi especially on a trip. The last two trips I was on i basically had a useless brick for a gaming console. Thankfully I had my switch.

Even after they made it “Better” it just seems like the Steam Deck will be a handheld PC rather than a “portable” one for me.

Make a mobile Hotspot via Smartphone. Then sign in. Done.

If you’ve got a phone with Internet, which you presumably do by posting this picture, just tether your steam deck to it and log in.
