Awful speeds wow!!

[#1]

Ive been getting ridiculously poor speeds for 1 week now. Speeds do not for the majority of the time go above 2mb. Even though stats below shows sync speed is 10mb which means i should be getting something close to 8-9mb at the least.
Uptime: 4 days, 20:50:49

This is a bit concerning
Error Seconds (Local/Remote):  5,652 / 0
FEC Errors (Up/Down):  0 / 36,627,663
CRC Errors (Up/Down):  1,149 / 12,226
HEC Errors (Up/Down):  1,151 / 109,433
Thats a hell of a lot of errors.

Is the phone OK with no background noise?

telephone has line has always been fine. dial tone has always been there without any crackling.
Just some background info, 2 months ago a BT engineer arrived and he replaced the master socket face plate into a split by openreach one, he also disconnected the adsl connections for the 2 other sockets in the house which as a result boosted sync speeds up and for the first time ever speeds were hitting 8-9mbs as they should've done all the time since I joined plusnet 4 years which however that wasn't the case since I I experienced poor speeds through out my time with plusnet being lucky to hit 4mbs at times.
I am happy with the fact I now know for sure my line is able to hit its sync speeds as it has done for the last 2 months but feel the job is only half done and that the remaining half to be solved now is what causes somany connection drops and errors on my line once that problem is solved I feel my line will never drop speed and I'll always have constant 8-9mb speeds. These constant connection losses and errors are hurting my speeds badly and it really is frustrating. I've tried getting plusnet to reply but they seem to ignore me every time.

You've had numerous threads on speed issues this year...

Since your (defective?) internal wiring was disconnected the stats you have posted have shown a consistent 10ish Mbps synch rate.  In one of your threads you reported that a BTOR engineer suggested that the internal wiring installed in your flat complex might not be up to standards - that is an issue which you might need to take up with the landlord.
Sight of all of the information requested in the speed issues thread (see below) would be very useful please.  Are the speed tests being done over a wired connection or WiFi?  Which router are you using?  Have you tried a different router?  Do you get the same result if you plug the router into the test socket?  (You will need a standard filter to do that.)
