Pass.

Mine start off 113 Max with 38 Max but now down to 98 Max and 32 Max

In reply to a post by adslmax:

Easy fix - turn off openreach modem for 24 hours. Turn off modem main socket first and then unplugged from the master socket. DO NOT USE IT for 24 hours.

Then plugging in the master socket and switch on openreach modem, it will now get maximum max downstream / upstream rate.

I did mine and it worked a trick!

That, I believe, is nonsense, and was a pure fluke in your case.

Adding my recent experience, on 28 June at 0400, my sync speed dropped from about 72Mbps to 60Mbps, where it has remained. Prior to this it had been running at a low SNR margin of around 3dB for a while, now it is back up over 6. I don't know whether this is due to crosstalk but I can't think what else might have caused it. Interleaving was off both before and after the resync.

I would imagine that you had some crosstalk that forced the SNR margin to go down to 3dB, eventually for whatever reason the line dropped (I'd imagine because of the low SNR), this then meant that the SNR went to the normal 6 and as such you lost the speed.
In a way you lost the speed when you had the SNR drop (not in reality but your max attainable would of dropped when your SNR dropped to 3 and as soon as a resynced kicked in the speed drop would happen).

That seems a fair assessment - my max attainable had been below actual for some time due to the low SNR margin, but I was surprised at the magnitude of the drop. The line had been stable at the higher speed (my highest ever sustained speed) for over two months. I am now (apart from a brief fault condition) at my lowest ever speed.

My line did something unusual.

At 1am one morning, quite a while ago now, the line went off, for a few minutes then came back up, it came back with a 4db snrm.

Now i would expect with a 6db target snrm, the possibility been my modem synced before others did so reduced crosstalk temporarily and then as the others synced up my snrm dropped. But my attainable speed matches a target 4db margin. So my sync speed of 75.7mbit, also had an attainable of 75mbit with a current snrm of 3.9db.

Lately the attainable has lowered a bit tho to 74mbit but I think with a 6db margin my sync speed would be way below that back into the 60s. The line has held like this, error rate not enough to upset DLM and uptime of over 3 months.

When I first got mine, got full 75mbps....

Now getting 50mbps @ around 200m - 250m from the PCP... Won't be surprised if it goes down further......

Yep affecting me a lot!

Full on 79.4Mbps on day 1 with 19.8 up.

3 months in down to 56Mbps up but still 19.8 up.

Two Openreach engineers have been out and test the line to the house and internally and see no problems. They asked BT to switch me to a different port in the cabinet but BT refused.

Had fttc since nov 2012 and for around the first year used to get a fairly consistent 76/19 Mbps, now i get 68 -70/18.5 Mbps
