If you're in an area where you can get ADSL2... make sure to change the "Modulation Mode" in your DSL modem to ADSL2 or ADSL2+ otherwise if you leave it on 'auto' it is likely to negotiate a lower connection speed.
P.S. All hail SNAP! :-) Being from the US and only in this country for about a month now... there is simply no other provider out there that offers the speed and bandwidth quotas anywhere even close to SNAP. I'm used to having a 12mbit down with 2mbit up and zero quota cap, so SNAP is about as close as I can get to that. :)
