So I plugged my TP-link router back in to the Hub3 via Ethernet with the Hub still in router mode and with the TP-link broadcasting as a separate SSID so that I had two separate WiFi networks running from different devices albeit both fed from the same Hub.

Today I had another complete loss of Hub3 WiFi, the SSID just disappeared from the available connections as though someone had stopped and restarted the WiFi. I switched my laptop connection instantly to the TP-link and that still had a broadband connection.

So to me it definitely seems to be a problem with the Hub itself, what else would cause the Hub to stop broadcasting WiFi in this way? The BQM for today looks absolutely rock solid.

Hi @thebands,

I am very sorry to hear about this. Is this issue ongoing for you today?

If so, can you try performing a factory reset of the Hub 3 to see if that helps at all?

Thanks,
