ADSL link down/PPP connection down

Since mid-September, my Hub Two keeps losing sync with the exchange, multiple times today with no rhyme, reason, pattern or logic. It's becoming incredibly infuriating and making it hard to work from home.

 

Looking at the router logs, at the point that I lose connection I get these 2 errors; "ADSL link down" and "PPP connection down".

 

I've had 2 engineers out who've found no issues with my line and the customer service at Now TV aren't helping much beyond that.

 

Anyone had something similar? Or seen these errors before? Any idea how I should proceed?

Re: ADSL link down/PPP connection down

I've observed my ADSL appearing to randomly go down and come up again... but by monitoring the logs of the router I note that this is absolutely regular, every 5 days at the same time of day

What's going on here?

Re: ADSL link down/PPP connection down

Piggybacking on this thread because my connection went haywire the other day.

 

I use a huawei modem and 3rd party router for my now broadband.

The other day my modem went crazy with errors and now my line speed has halved.

I usually get 54~Mb on my line speed and 10Mb on my upload.

Not sure what caused my modem to get so many errors because I never turn it off and it usually runs 24/7 for months on end.

Anyone else experience a similar issue? I'm in Hertfordshire for what it's worth...
