Broadband drops out repeatedly, No Ranging Response Received

Hi, my Hub 3 has been very unreliable over the last couple of days, I lose broadband and often I lose the Wifi signal too - could be the hub restarting maybe.

Anyway there are repeated errors in the router status log, like below, No Ranging Response Received, Unicast Ranging Received Abort Response and RCS Partial Service:

12/04/2020 09:16:32

critical

No Ranging Response received - T3 time-out;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.0;

12/04/2020 09:16:32

critical

Unicast Ranging Received Abort Response - initializing MAC;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.0;

12/04/2020 08:31:31

Warning!

RCS Partial Service;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.0;

 

I'll have to split the rest of the logs into multiple messages because, despite a character count of <3000, I can't post because I'm told I exceed the 20,000 character limit. Probably HTML added by the forum software.
