Ever since being persuaded to stay by having money taken off our bill (and then having a message saying its going up again by £3.50 🙄) our internet has been absolutely dreadful. Unreliable on wifi and ethernet, which isnt great when you are shielding and work for NHS IT trying to help coordinate the vaccination programme Via MS Teams and it keeps losing signal, but anyway.

Log below, im guessing the No Ranging Response received - T3 time-out are whats killing it each time.

Cant get through on the phone, so hoping someone can read this from VM and send an engineer out to sort it out.

That blanketpacket loss between 7am and 11am doesn't seem ideal...

That patch looks like a one-off, could be a few different reasons.  Apart from that the BQM is OK and your signal levels are fine too.  Check the BQM on a weekday and see how it looks. 

The log entries are spread over many days so unlikely to have caused a continuous problem.
