How do I install the latest pi 400 WiFi drivers (BCM43456

[andy kopac]

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.

Hi Sailoog
Is there a solution for this?  I'm trying to connect a RPI zero w now for a pypolot and it won't connetct?

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?

Yep!  It’s in the updates.  It works.  I did the updates before, but it didn’t work.  Looks like there is a kernel update.  That would do it wouldn’t it?
