Two yeas ago I installed a Ubiquiti PowerBeam M5 400 to connect with the AREDN mesh network in Marin county, north of San Francisco. Its firmware version is 3.22.8.0. It worked well until recently when it was dropped from the network. I've been advised that I need to upgrade the firmware to reconnect but the ARDEN download page does not appear to list firmware for the PowerBeam M5 400. All guidance to help me reconnect will be appreciated.
Thanks,

Guidance to upgrade a ubnt_powerbeam-m5-xw from 3.22.8.0 so that it will reconnect
to what firmware version neighbor?
If your Ubiquiti PowerBeam M5 400 is a 'xw' version like mine:
You could try to load one of the dozen or so more recent 'sysupgrade' releases found here:
https://downloads.arednmesh.org/releases/
You may need to start from a 'first boot' and load a more current release of
ath79-generic-ubnt_powerbeam-m5-xw-squashfs-factory.bin
You may obtain factory.bin firmware at the same URL as above.
