i am on a 2mb fixed line these are my line stats

Line Attenuation 54 db 15.5 db
Noise Margin 11 db 25 db
i have just checked on btw site and it now says the max for my line is 1mb fixed and 1.5mb max i have had a fixed 2md line for 2 years and now it is saying my line cant support 2mb do u think bt will change me down or keep me on my fixed line thanks in advance for the replys

I can't answer your question, but your line clearly supports 2 Mbps, so I can't see why it should be degraded.

If you report an intermittent fault and they see the attenuation which is outside the 43dB limit for Home 2000 they may downgrade to Home 1000.

http://www2.farina1.com/adsl will tell you how fast you are likely to go if using Max

So if you (the OP) have minor problems, put up with them rather than complaining to your ISP.

While Andrew was typing his post so I hadn't seen it, I was putting your figures into the calculator. You would get no advantage from going to Max and possibly get worse than now, so just play safe .

Except, if you were on an LLU ISP and getting ADSL2+ it looks like you might get up to 3Mb or a bit more. But on that attenuation they may not accept an order.

What is possible is that your internal wiring could be improved. See here. If your SNRM increased by doing what it describes, then Max may be worth considering.
