First of all, thanks to everyone taking the time to read this and for all help and advice given. Ade, there are no overhead lines or poles in my neighbourhood, in fact the telephone line is fed underground and into a flush plate in the wall, there are no telegraph poles and I don't know where the nearest connection cabinet is. I asked the openreach engineer yeterday, where it was but he didnt know! This morning I carried out a speed test and lo and behold my ip profile went up from 135kbps to 1500kbps overnight! Here are the latest test results :-

Download speedachieved during the test was - 1370 Kbps
For your connection, the acceptable range of speeds is 400-2000 Kbps.
Additional Information:
Your DSL Connection Rate :1952 Kbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
IP Profile for your line is - 1500 Kbps

I called the post office to ask them if they were continuing to monitor my line and apparently BT have said that they are monitoring the line. I have been advised by the post office to monitor my ip profile and if it begins to drop to call them back. My concern is that the line is by no means healthy, despite the openreach engineer giving it a clean bill of health yesterday. When openreach test a line are they passing it as being fit for speech or data or both? When I checked routerstats this morning I noticed that the rx noise margin is still fluctuating wildly. I have a link to the graph when the latest alarm was triggered:-

And my latest speedtest http://www.thinkbroadband.com/speedtest/results/id/1...

If the rx noise margin continues to be an issue is the only option to switch to a llu broadband providor?
While writing this yet another alarm has just been triggered
Alarm

Does anyone have any advice on what my next step should be and what would cause the rx noise margin to vary so much?

Regards
Derek

Keep a record of the times of these spikes over a couple of weeks or so and see if any patterns emerge. If a pattern is spotted, it may help to pinpoint the cause.

hello, im sorry to hijack this thread, but im having the same issue.

I did the BT test and i got this message Your configured download throughput speed for this service is 250 k

It was fine a few days ago, then it went dead for a day and now i get 250k, i cant browse properly or work. I usually get speeds of 5000!

all day today ive been speaking with AOL, 8 times ive called and they are just uselss. finally i got them to tell BT, now i await to hear from BT.

guess there is nothing i can do =(

What speed is your router currently connected at?

If you've had a low sync event your speeds won't recover unless your sync/connection speed has.

hi, I dont know much about these things im afraid, but this is the info i think you might need that the BT speed test told me...

Download speedachieved during the test was - 191 Kbps
For your connection, the acceptable range of speeds is 50-250 Kbps.
Additional Information:
Your DSL Connection Rate :7616 Kbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
IP Profile for your line is - 250 Kbps

Thanks

7616 is your sync/connection speed which is great

Your speed will increase as long as you can maintain this connection speed or a similar high one. It's all down to BT's IP Profiling system which is a pain for people on a variable line.

Speeds (IP Profile changes) normally increase around 3 days but can take up to 5.

What did AOL tell you was going on?
