My ip profile says 7168kbps down, but my true speed is 5.5meg.
That sounds pretty good to me. Do a Google on BRAS profiles. Here's an example of the profiles at the higher end of the scale:
5120 kbps to 5664 kbps = Up to 4.5 Mbps
5696 kbps to 6208 kbps = Up to 5 Mbps
6240 kbps to 6784 kbps = Up to 5.5 Mbps
6816 kbps to 7360 kbps = Up to 6 Mbps
7392 kbps to 7936 kbps = Up to 6.5 Mbps
7968 kbps to 8096 kbps = Up to 7 Mbps
8128 kbps = Up to 7.15 Mbps
So, as you're syncing at 7168kbps that puts you on the 6mbit profile and you're getting 5.5mbit out of it. That's pretty good and better than a lot of people get so you have nothing to complain about. If you move to another provider, you're going to see little difference. If you moved to an LLU ADSL2+ provider then you'd get a bit more speed due to ADSL2+ and the fact that they don't use BRAS profiles, but as long as you're on BT's ADSL network that's the way it is. This is all due to BT using ATM and that will all change when 21CN is fully rolled out and they will in turn offer their own ADSL2+ services.
This is not an "issue", it's just the way ADSL is. People complaining to watchdog are idiots because they're paying for an
up to 8mbit service. At my parents' house on "
up to 8mbit" I was getting 2.5mbit due to living quite far from the exchange. The chances are the majority of people whinging about not getting 8mbit are those who live such a distance from the exchange where it's physically impossible to get 8mbit anyway. At the end of the day, BT and ISPs are covered because of those key words. Nowhere does any provider guarantee anyone and everyone will get 8mbit 24/7, it's impossible to offer without spending thousands.
