any ideas?

I had it before with my old Vigour 2600 (which I bought new) when I changed to ADSL Max from fixed 1Mbps.
I can't remember the exact details with the model, but the connection would drop and not recover unless the modem was rebooted. I contacted my ISP (freedom 2 surf) they increased the SNR margin to 16db and the problem went away.

I just upgraded to a second hand Vigour 2800 and now am trying to maximise my connection speed. I contacted my ISP and got them to drop my SNR margin to 9db, my syn speed then increased to from 3.3Mbps to 4Mbps, but the old issue of connection dropout and no recovery starting happening again. Looking at it the modem is synced, but the WAN side of things is start at "Starting PPP". I also found telneting > adsl reboot got things started again.

I have found that I can force my Vigour 2800 to connect at a slightly lower speed ( telneting > adsl maxdnrate ), now this is done my connection seems to be stable again.

What for me is disappointing is that I bought Draytek products because I thought they were robust, and would recover if the connection is lost, not get stuck, but that appears not to be the case.

I would love to fix this issue, its most annoying. Try telneting adsl maxdnrate 3M and see if that helps you.

Dave
