Poor line stats, lots of crc errors.

Hello

Ive been having this ongoing problem for as long as i can remember as well as previous isp's, i seem to get an unsually high number of CRC errors, which i think is the result of having intermittent connection problems, and playing games online i get unusual lag spikes and stutters.
Ive tried to investigate where the problem might be on my line, ive physically detached the wires linking to all the phonelines in the house and even used different routers, ive also tried changing the MTU value then back to 1500.

My snr is usually very low, during the morning and afternoon, does it rarely go over 9.0db, during the evening however it drops sometimes to as low as 4db.

Im currently using a Netgear DG834GT, (having used a DG834, and Speedtouch 585 before)

Ive attached a picture of DMT tool screenshot to illustrate my connection stats which i took a few minutes ago notice the uptime to the errors.
Also where the line is coming in (the black box, which looks a bit suspect and very old) which feeds into a bt socket (next to it) which then feeds off to the adsl line upstairs, as far as i know the wiring is connected so the upstairs adsl box is the master and all other phone lines are filtered off this.

What do you think i should do to improve line quality, maybe getting a bt engineer to inspect my line ?

Ive also emailed this to aquiss.

your wiring looks like a mess to me,

id remove that crappy old black junction box and connect them grey pairs directly into an new NTE5 socket id, also do away with any of that exstention wiring unless you really need it

Same. You're not meant to touch it as it's BTs' property but when are they ever going to check?

yeah its simple to be honest, plus them grey pairs look healthy, nice guage, looks like copper too

Also, so many BT engineers do work on the sly that they are unlikely to be able to prove who re-wired the socket - their records just aren't that great!

Any ideas ? :<

just checked crc errors

Total time = 1 days 1hours 37min 32sec
SF = 25735356 CRC = 445209

:O

as said before you need to get rid of that black junction box

Fit a filtered master socket in place of the black junction box. See if there is anymore cable available to be pulled thru the window - but even as it is it should fit ok below the sill. When threading the incoming cables into the new backplate tape their ends so that there is no danger of them touching eachother or anything else! It does not matter where the c 2 cables go A or B.
Then check out the rest of your wiring making sure its cabling is all ok

Hello, can you elaborate on what wires should go where etc
