      Re: Pretty sure I am being capped?

      Whether your router drops out or not at a low noise margin is largely dependent on the firmware.

      The target noise margin is applicable when the router initially syncs with the exchange equipment following a reboot/resync. What happens is that the router will sync at the highest speed it can for a noise margin of 6db with O2, 6.9db with Sky. From that moment on, the noise level in the line may change, up or down. If the noise goes up then the margin drops. If the noise goes down then the margin rises. The sync stays the same until a resync occurs, when again the router syncs at the highest speed it can for the default margin taking into account the noise level present in the line at that time.

      The noise margin reported by your router is not a measure of noise on your line. It is a measure of the margin it has given itself when it negotiated with the exchange (and subsequently adjusted to current line noise). This is in effect the difference between the actual SNR and the SNR the router requires to run stable at a given speed.

      Thanks for the explanation. What I will try to do is raise the target noise margin with the dmt tool when i get the 2740b. As you are aware, o2 can only raise or lower the noise margin in 3's so what i will try to do is sync with a 4 or 5 target margin and see if i can still sync at 8188, the max sync for my package.

      Can't believe it...My speed has dropped from 3Mb to less than 1Mb. Spoke to Sky and ddissapointingly they can not do anything. Feels like i have been lied to. The customer rep's excuse was "There are more sky users in your area hence the speed drop". Speed drop of 2Mb??

      That is rubbish, what are your router stats, can you post them again just too see if they have changed.

      Another call to CST late evening may be required.

      Your attenuation has risen by 3 to 50 dbs. This suggests your line may have been put on ADSL2+ which is not suiting it. Try to get through to CST and ask if you can be put back on G.dmt and your line configured as it was originally.

      If this is not the reason for the rise, then your line has developed a serious fault.
