Usual helpful offshore CS help then?
What Hub model do you have and what are the various Hub lights showing/doing when this happens?
Then check for “known network faults”
As well as trying the “check service,” Area status webpage" (link at top right of this forum), 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 postcode level.
If nothing shows there, then before looking deeper, can you say, are the issues only evident on wifi connections or do you see them at the same times on devices connected on ethernet cables?
If you don't know, can you check to help diagnose whether it is just a wifi issue or it could be network connection related?
