Yes, that doesn't look right.

I got home, did a factory reset of the router and within 2 minutes of being up (when it let me back in) there were over 37000 FEC connection errors on the Fast Path.

Managed to source a TP-Link W9980 VDSL router for some testing. Plugged it in and ran the setup. Generated about 23000 errors in the first 5 minutes up; been running for 20 minutes now and the errors stopped occurring after the initial first 5 minutes.
Router is detecting the line can provide up to about 55Mb, so guess it's a waiting game now to see if any more error packets are generated and if the line retrains itself to providing full speed. Hopefully a new BB2 router coming in the next couple days behaves better.
Otherwise I'll be investing in a better router!

20 hours up on the TP-Link router and I'm getting very few errors:
Upstream Downstream Current Rate (Kbps) 13713 35000 Max Rate (Kbps) 13838 45260 SNR Margin (dB) 6.2 9 Line Attenuation (dB) 24.6 19.7 Errors (Pkts) 35 23654
Though my max rate on downstream has dropped to 45Mb from 54Mb on initial startup.

Not great, sadly.
Spoke to an EE guy called Dylan yesterday who assured me I was in the queue to recieve a visit from an OpenReach engineer - as his test from yesterday reported a line fault - and he would call me back to book me in. That never happened, so I called EE again.
Another technical support agent had me plug the BB2 back in to run diagnostics, which is fair enough, but when it generated 1.9 million FEC errors in 15 minutes, they had me change the WiFi settings on both 2.4 and 5 GHz channels to 'N' only - claiming it would make things 'go faster'.
And they ran another line test which yielded no faults. Though the positive is the replacement BB2 has been dispatched and OpenReach are coming tomorrow now. (And I put the TP-Link router back on and after an hour its generated precisely zero fault packets)

The Max Rate is purely theoretical & assumes the line is not profiled at all, mainly that the NM = 0 dB at which point it becomes v. unstable. It will increase as the NM decreases. I bet the NM was lower than 9 dB on initial startup.

LOL! WiFi connection influencing router sync speed & error counts! Indeed!

SNR is currently at 9.9. Last night it dropped to around 8
And yeah, although I followed her instructions, I snorted with disbelief when she said that. And when I countered with the 5GHz band being kinda designed for AC (which the BB2 of course provides) and why would I limit it to N when AC is much faster, she didn't really have a comeback.

OpenReach engineer came out this very morning, prompt at 8 a.m. Ran a battery of tests on the line - no fault with the line. His diagnostics confirmed the line was delivering 58211 Kbps but was capped at 34998Kbps - and also detected no FEC errors for the duration of time he was here.
He suggested I phoned EE to get them to remove the cap, who're now sending ANOTHER engineer out this coming Monday to do some fiddling - this person presumably has the power to the phone the OR Diagnostic Centre of Excellence to remove the cap on line, assuming no other errors are generated by my TP router or the new BB2 coming today.
It's all very vexing.

I'd love to get to the bottom of it too - Qube engineer came out on Monday morning to have a poke about. Disconnected an internal slave point (3 feet from the master - new build - don't ask!)
FEC errors seemed to die down, not to zero, but enough for him to be happy and disappear again. Phoned through to EE to get a DLM reset, but was told the fault was still with OR so someone would be in touch.
After the Qube engineer left, I went away for a few days with the fam, came back today and found the FEC count at roughly half a mllion - and that was from a reset this morning as we'd had a power cut! System had been up roughly 6 hours
Interestingly though, the downstream count had increased from 34998 to 49000 (Kbps) and NM had dropped from 11-point-something to about 6 while I'd been away.
Plugged in the TP Link router (again) left it whirring away while I unpacked and after 20 minutes wandered back and found it had generated about 3 error packets.
And so the saga continues - the line is perfect, yet the new BB2 is spamming FEC errors

What are your router stats now?
27-04-2017 05:27 PM
Had to put the BB2 back on as I'd only borrowed the TP and I'm going to be phoning EE again tonight - you must have posted as I was making the swap!

Router reconnected itself at about 9.45 this morning, downstream has dropped from 49k to what's below - DLM doing what it's supposed to. Probably on account of the ridiculous amount errors:
