Certain wifi networks not showing

[expant]

Hi All,

I have an interesting problem with my PPP whereby certain wifi networks stopped showing all of a sudden, even across multiple OS's on the phone (where they previously did show). I have other devices that can still see and connect but for the PPP these networks have vanished? No configuration changes, has anyone else experienced this?

Try adding "ccode=NL" (or JP) line to /lib/firmware/brcm/brcmfmac43455-sdio.txt and rebooting, some of those networks should appear.
This is not a proper fix, but I haven't found how to fix this and similar (like "ccode=X2" no longer working on GPD pocket) broadcom regulation problems properly.

That file doesn't exist, I tried to create it with 'ccode=ALL' and still no dice.
