Try downgrading the firmware-brcm80211 package. Download firmware-brcm80211_20190114-1+rpt4_all.deb locally (or copy it to the SD card) and install it with

Code: Select all

dpkg -i firmware-brcm80211_20190114-1+rpt4_all.deb
I seem to have a similar issue with the firmware-brcm80211_20190114-1+rpt5_all Wifi firmware update - can't connect (2.4Ghz or 5Ghz) on a Pi4, downgrading the firmware package brought back the Wifi.

You can find the old package http://archive.raspberrypi.org/debian/p ... e-nonfree/.

The old package firmware is the best solution in most cases.
