I have just run network diagnostics on my Hub 3.0 after pinhole rest and buying extenders has failed to solve ongoing WiFi issues.
The diagnostics say there are no issues with:
temp of hub
but then says that every single device currently connected to the hub has low signal strength and I need to move it closer to the hub (including the iPad I am doing the diagnostics on, sat right ne t to the hub!)
Has the WiFi transmitter in the hub given up the ghost, or is there some way I can fix this?
Put it into Modem Mode and attach your own router or mesh system and be done with the hubs wifi.

Did as you suggested Gary, and since switching to a separate router (went with Deco mesh network), have had not a single issue, and can even have TV on wireless without impacting other users. Thanks for the advice!
