Two Defective thermostats

[olis]

One thermostat shows a W5 error and now can't reconnect to network. All recommended checks completed. Other nest thermostats are on the same network without problem and no external factors or interference has been introduced so it is a hardware issue.

It was suggested on an earlier thread that I try to

1. Press your Thermostat's ring > Settings > Software > Update > Connect.
2 Reset the network settings on the Nest Thermostat from Settings > Reset > Network.
3. Restart your thermostat from Settings > Reset > Restart.

I also have a second defect thermostat or heatlink which fails to connect over Mesh unless with about 5m of the each other rendering it useless as it isn't able to measure of the heating zone it is controlling.
