And now he thinks he is being "throttled".
The TT forums are the best place to get the issues resolved, but the way his thread is going, with TT not finding any fault, it seems likely that they will suggest a home visit by an engineer. But if they can't find any line fault they can't escalate to BTOR, so it is likely the visit would be by a TT (BrightSparks ?) engineer.
This could well be chargeable, and possibly wouldn't happen during the coronavirus lockdown.
But one thing - tell your friend to stop turning his router off every night. The BTOR DLM system doesn't like trying to talk to an inactive router when it is on an active fibre line. All ISP's recommend fibre routers are left active 24x7. Switching off at night can cause DLM to negatively react and will then take several days to recover.
