Are ethernet cable connected devices affeted too ? If you don't know, can you check to help diagnose whether it is just a wifi issue or it could be network connection/Hub related?
What Hub model is it? What are the various Hub lights showing/doing when this happens if a Hub3 is the base light a steady white(ish) or flashing green?
Also try the “free & automated” Service Status number - 0800 561 0061 - which usually gives the most up to date info. and tells you of more local issues down to street cab/ postcode level.
These may not be listed on the Area Status web page (Areas are not Geographic” they are billing areas) as that usually only covers faults affecting 1000’s of customers) so phone may give you more info, but even that wont cover problems affecting just a few customers - or just you.
The "compensation "timer" can also be started on this number.
If nothing shows on there, try calling it in as a fault (free on 150 VM line - or 0345 454 1111 others - national rate) and see what they say when they test your connection. If they say it’s a known fault, get a fault reference number.
Or, a VM person should pick this thread up and be able to help but it can take a few days.
