deakink--You might try

However, I do not know if you will have problems running the diagnostic from the UK.
There is also this site.

DrTCP is often very helpful. As is the advice under #5 RWIN.
If you are being charged for faster speed than you are getting, BT really should try to help. At minimum they should come out to test your line.
Do you have any alternatives if they are not?

thanks for the reply been on to bt helpline not that helpful will try those sites by the way the upgrade to 8mb was free

Work on the sync speed reported by the router's web page first; that will be completely unaffected by MTU, RWIN etc. The sync speed is purely a function of the router and the line between you and the ISP.

Make sure all the other devices (phones, faxes, dialup modems etc) on your line are properly filtered; that sort of issue becomes more serious when the potential speed increases.

Even if you think they are, unplug everything except the router from the phone line, then power-cycle the router and see what speed it syncs at. It's rare, but those DSL filter devices do fail.

If you still get crummy speeds with nothing else on the line, it's a line quality issue, either within your house or between you and the exchange. ADSL is distance-dependent, but you shouldn't have lost that much speed just as a result of the ISP uncapping you.

Have you power cycled the modem so it picks up the new firmware?

hi everyone
thanks for the replys been through those things with bt must be down to line quality and distance from exchange although bts first test said we could get up to 4.5 mb speaking to them tomorrow to get them to come out sometimes if they change the pair from the pole it can help a lot other thing is before the upgrade we were getting 2.2mb with no probs now we get 1.4 mb at best mad isnt it
anyway thanks for all your help if we get this resolved i will let you know what they did
