Hi, I have noticed since going on 21CN my internet speed in the evening is really slow and web pages are taking a long time to load.
If I do a speed test in the day its pushing 5mb in the evening its 1-2mb, when I was on 20cn it was a constant 4-4.5mb.
Can something be done about this as my contract is up soon and I am considering other providers if it does not improve.
Thanks
Graham

Other providers who will put you back on the "Up to 8 Meg" ADSLMax service that you had before your exchange was upgraded? I think Plusnet can do that too, if that is what you want.
I found that when I moved from 20CN to 21CN that my SNR margin, which had been rock-steady on 20CN became much more sensitive to night-time conditions and now drops by 1 to 1.5dB when it got dark. I have seen other locations where the drop-off is more extreme. If your SNR margin gets too close to zero then you can arrive in a state where your effective speed is much lower than your sync rate because too many data packets get corrupted and have to be resent.

Once an exchange has had 21CN enabled BT set a date when 20CN will be turned off - you can find out if the date has been set and when it is by putting your phone number in to http://www.dslchecker.bt.com/adsl/ADSLChecker.AddressOutput
Going back to 20CN isn't a long term solution!

Going to another provider isn't a long term solution either; it's not even a short term solution. So I got the impression the OP just wanted a quick fix.

Hi Graham,
I can't see any issues on your line to be causing this, are all the speed tests over a wired connection. If so, I'd suggest raising a fault as we'd need to take a closer look at this - http://faults.plus.net
