Up until a few weeks ago my sync speed used to be around 4500 but over time it has dropped to about 2700. I used to be able to bring it up again by re starting the system ( re booting the router) bu now even this does not help.
I have not changed, added or taken anything away etc so it cannot be anything that i have done.
If anyone has any ideas what the cause may be and any possible remedies i would be very grateful.

If the stats are pretty much the same, then you've had some issues causing you to drop sync and re-sync frequently. Start by having a check to see if you can hear any noise on your phone line. Any crackling or other intermitent noises that you can hear or have heard recently?

I just cannot make this out but something somewhere must have changed to make this happen.
Don't you just hate it when something like this happens for no obvious cause. I just hope that someone can help otherwise i'll be stuck with a lower speed and have to "put up with it"

Has your noise margin always been that high? It does seem rather high if you were previous receiving a faster speed. My initial assumption would have been that it had increased.
Can you please ensure that you are connecting directly to your master socket via a filter (test socket behind the master faceplate is best if possible) and try using a different microfilter.
That may help improve the quality of the signal a touch.

No need for filters etc as i have one of the new BT faceplates that has 2 sockets, one for the phone and the other for broadband.
Ha, so thats a couple more ideas out the window...........................unlkess i could talk PN into lowering the noise margin and seeing what happens then.........

Any chance of trying to borrow a router from a friend to see if you get the same noise margin / speed on the line?

I have another router, same make/model. I have already tried using it but the figures still come out the same.
If i try to raise a speed fault i go through all the checks and then it tells me that everything is alright. Can you tell me if i can bypass this and just ask PN to ask BT to lower the noise margin?
Regards

I was under the impression that raising a speed fault wasn't necessary to get the noise margin lowered given that a speed fault requires 3 BT speed tests which are a waste of time
