I've been with Virgin for years and have always had parts of the house with bad wifi. About 6 months ago I upgraded to the top package and changed the Hub to router mode and added google nest mesh. This has been fantastic and the general performance has been way better - I particularly notice this on some Sonos speakers which were further away and used to drop off a lot - they never do now.
However in the last week or two I have been having frequent dropouts again. I have checked the Hub settings and I seem to have a lot of Critical Errors saying "No Ranging Response received - T3 time-out;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.0;"
(Over the years most problems I have had have been to do with the connection to the box down the road if that is in any way relevant.)
