At first I though it might be due to Thames water digging a big hole in the pavement outside, but I've been running routerstats and I don't see any obvious signs of REIN (I had a lot of REIN last year but that seems - touch wood - to have gone away).
My router is reporting good synch but browsing is horribly slow.

The router is connected directly to a newish BTO faceplate.
Could it be a faulty router?
[Or is this a Plusnet-wide problem?
There seem to be a lot of reports of poor browsing/good synch in the various forums - I just noticed an almost identical thread was opened before I started this one. ]

I haven't detected any obvious interference using the radio test for the last few months (and the speeds I'm getting now are worse than when I had obvious REIN).
I've attached a few recent routerstat graphs if it helps.

If you are clocking up CRC errors at about 5 per second or higher (I'm not sure of the exact rate when it will become easily noticeable), that will be the cause of the slow throughput speed and poor web browsing. Sometimes a graph of the increase in CRC errors since the previous sample can be very useful in displaying the size and timing of the problem.
The high error rate would be some kind of line or interference or modem/router problem. Unless, perhaps the target SNR margin is 3, and that's just too low? Despite the low SNR margin, the speed is still below what could be expected for the attenuation, so it would have to be a below average quality line or an always noisy environment, if the target SNRM is actually 3.
It's a shame you didn't get a 582n in your previous thread, because Plusnet supply the Sagemcom 2704N now, which isn't as popular and apparently doesn't work with RouterStats.

I have to go out now but I might later try disconnecting again and switching off the router for a couple of hours or so before reconnecting again though I'm not sure if it's a good idea to disconnect again at this stage?

Is the line quiet. Dial 17070 option 2.

I tend to believe the TBB result as most sites are still like treacle.
Hmm, I think I will disconnect/ reconnect in a minute.

Quote from: Townman For the attenuation, that synch rate is a bit low.

It was quiet when I tried it earlier.

No disconnects or anything obvious in routerstats (to my untrained eye, at least).
Bizarre.

ping -n 50 212.159.6.9
ping -n 50 -l 1400 212.159.6.9
The problem is visible from the large CRC and HEC error counts in the stats.
The low BT speedtester results should make it fairly easy for a slow speed broadband fault to be accepted, although if it were me, I would try another modem/router first. Or you could just raise a fault to get a line test done, to see if the line test shows some obvious problem for Openreach to fix.
