Two units no longer connecting to any wifi

I have three units, one outdoor, two indoor.

About 8 weeks ago, one of the indoor units disappeared off the dashboard, so I checked the wifi access point and it showed that the Airgradient unit was missing. I spent a coule of hours trying and retrying to get it to connect to various wifi networks, but it will not connect to any of them. The Airgradient access point works ok, but after setting a network, the unit never connects.

Three days ago the outdoor unit disappeared after powering up after a power outage. It is now the same, it will not connect to any networks.

I’ve reflashed with the latest firmware, and also tried going back to 3.0.8, but still the same, the Airgradient access point allows me to log on and configure the wifi, but no connection ever happens.

Now I’m down to one unit out of three still functioning, it still shows on the network as connected, and its data is still on the dashboard, but for how long I don’t know.

Can anyone suggest how I might get these two units back online?

Thanks,
Jason.
