Random Disconnects

[#1]

In recent months I have had 3 broadband providers and 3 different routers but I am still having random disconnects.
I have changed the microfilter and I have a new installation of Vista on my PC.
My current router model is a Zyxel P-660HW-T1 v2, below is a selection from the router logs when a disconnect happened.

I have tried everything and this is very frustrating for online gaming. Please help.

Hi there,
Sorry to hear you're having difficulties. Sounds very much like you could have a line fault if the problem's been evident across multiple routers and when using different ISPs.
Does the sync/link/line/dsl light go out or start flashing when the connection drops? The first thing to do if you haven't done so already would be to unplug *all* other telephony devices from your line (including things like SKY boxes etc.) and plug your router into the master socket avoiding the use of any extension cabling. If that fixes it then it's going to be something to do with your local setup. If it doesn't fix it try swapping the microfilter.
Next step would be to raise a fault via the Member Centre.
