I use OP extensively and put a fresh install and update and upgraded on a pi 400. I can use 5ghz, but 2.4ghz refuses to work. I have a printer on 2.4ghz. I even ran the WiFi driver install in the OP apps. Has anybody else run into this problem? I did some searching and there have been some driver updates. I’m thinking this should be in the image upgrade for OP if it’s not already.

Difficult to me to debug, I have not the Pi 400. some tips:
- Have you tried with a fresh Raspberry OS? if this does not work in Raspberry OS it will not work in OP.
- Have you tried OpenPlotter 3?
- Have you tried with another wifi channel?
