When it works it's usually around this speed:

I attempted a TBB Speedtest:

Welcome to the new version of the thinkbroadband speed test.

We encountered a problem
Error Code: 4134 (Suspect download behaviour)
Check you have an Internet connection and try again
retry
Cancel Test
This error occurs when we see no data or there are anomalies.
Check your connection is not busy doing something else.

Turns out the internet connection has now gone completely.

8 - Maximum data rate: 756/444
9 - Noise margin: 11.0/6.4 Given noise margin at 6db, it indicates the line has no extra capacity, so the line is performing as good as it can under the circumstances. Almost definitely points at a fault, should be way over 444kbps at 44db attenuation and 6db noise margin
10 - Line attenuation: 30.0/44.0
12 - Data sent/received: 6.1K/25.0K

My advice - formally raise a complaint in writing (not phone).

Thanks, for the link. The Max data rate has been going up/down all night - so something isn't right.

I�d agree with your diagnosis ... and at the start of the thread weren�t they mentioning their detection of a loop condition on the line ? There�s iffyness on the pair somewhere I suspect.

Thanks for the info. I'll see what they have to say - calling is quicker, the online messages get answered about 3-4 days afterwards.

After a reboot, things seem stable - still waiting for Plusnet to come back to be see what they are going to do. I'm currently in the 72 hour waiting window for someone to action the call!!

They've checked the line again and every 15 minutes there is a consistant error appearing. They are now getting someone to come out and check the fault out tomorrow (which is handy as I'm off).

Fingers crossed you don�t get some �tick the boxes and run� noobie....

Politely earwig over their shoulder and watch the PQ test results come in, ask them to explain each of the results , and don�t be fobbed off with �It�s all green ticks mate�.

I�m hoping the CP has actually booked an SFI visit, not some cop out CDTA task.

Good luck.

Hopefully it's sorted now. The engineer ran a line check and it was displaying a few crosses. He popped to the local cabinet and found the connection to be corroded - he said as soon as he touched the wire it broke off. I'll keep monitoring it, but at the moment it seems fine.

It's been a week and all is well, so looks as if the old Cab connection was the issue. £30 compensation for lack of service is much welcomed.
