So I’ve had a regular steam deck since launch, and I’ve never dealt with the 5ghz WiFi issue. Yesterday I got my new oled model, and it refuses to connect to the 5ghz WiFi. It works with the 2.4, but not the 5. I’ve tried the power save setting, and still no luck. I really don’t want to send it back, but the download speed on the 2.4 is horrendous. Any ideas how to fix this easily?
Try different channels and channel widths on your router/AP. You can also try different security types.
