I'm getting the same problems, had the free upgrade and getting connection problems, seems more stable when I changed from 6db to 9db but still getting problems. I get reconnected back to the exchange but wont go further to get DNS/IP etc from ISP, takes a few rooter reboots to get a working connection. Was pretty stable before all this. I'm not bothered about the extra speed I just want a stable line that dont drop. I'm using a Netgear DG834GT router with old firmware.

Quick update, for the past 2-3 days my connection has remained stable, no drops and its still at 9db, this seems to have been a good move to make. Need to see what happens when I reboot router to see how it reconnects but at the moment increasing signal to noise ratio has helped alot, I'm pretty happy with the result but still monitoring it.
