Re: Throttling problem
I can think of a couple of things - neither of them would be good news for you but might explain it:
1) Most residential ASDL lines have a contention ratio - ie although the line to your house is your own, the pipe from your local exchange is shared with all the people on your exchange, and not wide enough for everyone to download at max speed at the same time. In this country (UK) the ratio is typically something like 20:1 - ie 20 consumers each promised 4 Mbps actual pipe is 4 Mbps. So any single customer can hit their 4Mbps providing nobody else is doing much... but if others are, then there is an effect. You can see where this is going... if you've gone from a local exchange where the other 19 users are really light, or where there were only a couple of users connected at all, to one where there are a couple of heavy users, you'll see a drop-off in bandwidth, but from time to time you'll see (briefly perhaps) the full speed.
2) ADSL speeds are MAX speeds. The further from the exchange you are the slower your connection will actually be. I don't know what the limit to what they consider allowable distance is where you are, but it could also very easily be the problem. So long as you're within that limit they may well tell you your connection is just fine... without necessarily meaning you can download as fast as if you were closer to the telephone exchange!
