Hi,
Yes this is a standard faults response to an intermittent connection issue.
It's basically making sure that everything's been tested before the fault is passed to BT and an engineer has sent, in order that there aren't any AVC (abortive visit charges) charges issued - the ones that BT charge if an engineer attends and finds that the fault is caused by some equipment plugged into the line or some internal wiring.
It can be summarised as - test the router in the master socket with everything else unplugged from the line. If the fault is still apparent, check to see if it happens at the same time each day and if so see if it could be electrical interference (that's why you see so many posts relating to Christmas tree lights during the season). Also test a different router in the same way.
If the fault still happens with the other router, you've proved it's nothing at your premises and we can escalate the issue knowing there won't be a charge issued.
All the techy stuff in previous responses is for our faults team, so they know what's been tested and when and also what state the line (and fault) was in at the time of testing.
Hope that clears things up a bit,
