Thanks for that. From what I can see the only time the system up timer resets is when I do some thing. I'll keep a record of it for a while though just to be sure.
Thanks again.

Just a thought. If the WAN is up and stays up, why would it re authenticate?

Might be worth having a look at RouterStats which will collate and graph relevant stats. See http://www.vwlowen.co.uk/internet/files.htm

Because of an issue at the ISP end that handles the authentication, i.e. logs you off perhaps

OK Thanks. So that's not nesesarily associated with a resync.
So am I right in sayimng that if I sync at 6752 kbps and my router shows an uptime of >5days my profile speed should increase?

Thanks John I'll have a look.

Should do. Can't be 100% as it is possible for a router to drop the link and resync and the user interface to not update.

Resyncs themself are not the problem, you can resync a number of times a day, but if always around the 6752Kbps mark, then the IP Profile should still improve.

OK thanks. I should have said if it doesn't do any resyncs at a lower speed.
I'm running routerstats for a day or so at the moment to see what that shows up.
I wish BT would take some responsibility without the threat of massive charges if they find no fault. Who's the bl**dy customer here

In reply to a post by john2007:

If you restart your router it will sync as high as possible given the current line conditions, so if you replace a faulty component the sync rate will improve immediately. However BT's profiling system imposes a cap at the old, slower, sync rate for up to five days.

Just reading this again John.. So if I already have a good sync rate as I have now (6725kbps) but my profile is capped to 1.4Mbps. If I change a faulty piece of kit I won't see any difference because the sync rate won't change and neither will my actual data rate. Am I reading that right??

Wrong

Sync rate changes are instant always

IP Profile which governs data rate will not change, may take 1 hour to 5 days to change
