There may be a DAC box involved if it was a shared line in the past, that can also lead to the problems you are experiencing.

I didn't think it would work at all if a DACS box was present? If there is one how can I tell?

If you had DACS you wouldn't be able to receive broadband at all.

It's not compatible with a broadband service.

If you drop a ticket number in here, I or a member of the digital care team will be able to have a look.

Hi James. Good to know you are still around. i remember you from the original Metronet days!

I didn't want to trouble plusnet with a ticket without doing a few checks myself and seeking the opinion of others on here. The strange thing now is that looking my current line profile on the Plusnet web site it states that my line speed is currently 3.4Mb. Could it be that while my back is turned its behaving itself? I bet the speed is pants when I get back there on Sunday.

I noticed that the SNR was looking a bit on the high side, so wanted to check for things like banding/errors to see if there was an obvious fix.

I was just after a ticket number so I could locate your account without your having to post a username.

Feel free to drop me a PM and I'll see if there's anything obvious.

The only high number in the errors figure is the number of error seconds.

Please can you turn the router off for about five minutes, then on again, and as soon as it is all up and running give us a new full lot of stats. We need to see the noise margin asap after the restart, so we know its base figure .

James has done something to reset the SN value. I've only just managed to get back here to check the router. Before the power cycle just now the download speed was 1,180Kb and the SN about 26dB. After the power cycle I'm seeing the much improved stats shown below and it hasn't changed after 25 minutes. BT is giving an IP Profile of 3.64Mb but only gives a download speed of 1.01Mbps. Plusnet show my current line speed as 1.2Mb in the Member Centre. Do plusnet have a speed limiter too? Fingers crossed it remains stable.

That looks fine.

Something must have upset it in the past for the margin to be 9.5dB. There is a possibility that if it runs smoothly with that 9dB sync-time margin then the DLM will drop it to 6dB in 10-14 days. Just keep an eye on how it varies 24/7 anyway. In case there are any big sudden swings.

The Current line speed you have quoted is a copy of the BT IP Profile rounded down a bit. They do limit your speed to that.

It gets updated automatically a few times a day so should rise soon. If it is the same this time tomorrow that update has failed and you need to ask them to do it manually. Don't go doing a lot of re-sync's to try to jolt it. That could send the 9dB up to 12dB and cost you connection speed (bandwidth).

Thanks for the quick reply and your advice Bob.
According to BT my IP profile is 3.64Mbps after running their speed test. Actual throughput is 1.11Mbps according to speedtest.net. I'll hold out for it to improve over the next few hours.

As soon as line speed shown in the PlusNet Member Centre catches up with the BT Profile your speed will increase as well. As Bob said, this can sometimes take a day, but it will catch up and once it does you'll be downloading at double your current speed.
