Flashed the new firmware, then a factory reset via the router interface and the reset button on the node (not sure I needed to do the latter). Then set both units up via the app before moving the node to different location. The only settings I change are to separate the 2.4 and 5 GHz bands with different SSID for each and give each band a control channel, rather than leave it as 'auto', to avoid interference. No other changes at all.
Yesterday, it would all work for perhaps an hour or so; then initially the 5G-2 backhaul channel disappeared (the router interface showed the connection quality to the node was 'weak' and the uplink type was via 2.4GHz) so I did another reset and reboot on the node which sorted that. Another hour or so, the node would stop broadcasting on 5G-1 which a reboot would solve, but only for a limited time. In the end, I must have rebooted the node about half a dozen times including last thing last night but this morning 5G-1 was not there. I'd more or less decided at this point that I was going to send the units back but I did a reboot of the node to get the system working and it's been stable since then (9 hours ago).
It was all very frustrating and it doesn't look like it's a hardware problem given it's been fine all day today. I know others have said several reboots can be necessary after flashing the firmware but the amount of reboots I performed seemed way over the top. Perhaps not...
