ADSL2+ IP Profile 20Mbps - Actual Speed 16 Mbps

[#1]

Does this sound about right?
I've just transferred onto 21CN and I know that speeds will be a bit odd during the 10 day training period, but if my IP Profile is already at 20.25 Mbps then I'm assuming that I would see faster speeds and the training period is just homing the IP Profile to a suitable one?
Line Stats on my DG834GT router are:
Connection Speed : 22906 kbps
Attenuation : 9.5
Noise Margin : 2.2
Is it time I bought a new router? I hope not as its a workhorse! and I only use it for the ADSL modem.
Cheers

If your connection speed is 22906 your IP Profile (as shown in the results of a BT speedtest) will be 20203.
That is your Current Line speed shown here?
16Mbps seems a little low (but not a lot) for that IP profile. Are you using a wired or wireless connection to the router? What OS are you using on your PC, Windows 7 or something else?

ahh ha, current linespeed has changed by the looks of it, it is now showing as 18.3 Mb, previously it said 21 Mb which got me confused.
I've tried several speed tests, Mac OSX, Windows, both wired.

Hi there,
Looks like it's currently set at 20100 on both ours and BTs side, but it's probably worth running a BT speed test to see what that shows you're set at - you can do that at http://www.speedtester.bt.com
