What a load of utter tosh.

If the voice line is making calls perfectly well then no point in you calling BT.

Demon have a duty to inform their wholesaler if there is a fault, and not try to farm responsibility for fault finding and rectification on the consumer. Point out to Demon who you pay for broadband.

A real danger exists in that if BT voice faults fix the problem they may do so in a way that improves voice, but makes the broadband worse. That is the focus of their fault resolution, if Demon report the fault the emphasis would be on the broadband.

Thanks for this - I'll ask them why they didn't do it when I speak to them next. As you'd expect it's really difficult knowing who's being straight with you when trying to deal with things telecom related and who's giving you good information.

Ah - so after settling down for a week or two, the whole "lose the connection + multiple restarts" loop has started again, culminating in 5 hours of constant reboots last night / this morning.

It's possible it's the router, and I'll see if I can get hold of another device. The current one is a 6 month old Linksys X2000 - if anyone can recommend a robust alternative that would be helpful.

A call to Demon at 9.40 led to an Openreach line test this morning that yielded the following result:

Test outcome: Fail
MFL: LN

A similar call to BT 30 minutes later contradicted this test result and said everything was clear.

A subsequent call 30 mins after that to Demon confirmed the BT result.

Aside from changing the router, is there anything else I can do?
