Have I been restricted on this line? should I be getting more?
please find my line stats below:

Your sync seems appropriate for your attenuation.
|
|
|
I think you're looking at the wrong bandwidth Downstream sync speed of 3834 kbit is 3293 kbit slower or 54 percent of the average for connections with the same downstream attenuation of 44.5dB

What stats do you get if you plug your router into the test socket within your BT master socket?
|
|
|
|
using test socket and restarted router
but still the same
|
|
|
No, but that's some pants statistics, you got all your filters in place ? Got a noisy line maybe ?
|
|
|
|
|
|
|
Likely some line issue, but may be worth trying a factory reset of the O2 Box

i will try do a noise test on the line.
if its noisy what does that indicate? and how to fix it? by BT?
|

switched the router off..
did a noise test this morning, and sounds clear..
switched the router back on
heres my line stats (its sure looks different)

Does a corded phone work? Could we have a photo of the wiring in your master socket/detachable faceplate?
|
|
|
|
i will need to get back to u about the faceplate.
gotta go to work now, its my last day today anyway =)
|
|
|
Lucky you! 
|
|
|
After just less than 4 minutes, all those HEC errors look bad .....
HEC Errors (Up/Down): 10,143 / 1
They would appear to be mainly upstream also, possibly an issue with the card in the exchange ? Something is causing the downstream sync rate to be low for the reported attenuation. You say you have already tried in the test socket, and I guess with a good know working micro-filter. Next step is to push for Be to get an engineer out.
|
|
|
|
The upstream errors will be cumulative - they don't reset with the router - so the number of upstream errors versus the router uptime isn't really relevant.
John.
|
|
|
But there were none on the first set, and a fair few on the second, 4 mins later..... ? The router is either reporting them wrongly, or they have been clocked up in the first 4 mins.
|
|
|
|
The set of results with no HEC errors was very shortly after router restart. Perhaps the router hadn't been sent the exchange HEC errors at that stage? I'm not sure how often the local/remote end exchange error stats.

i'm back from work.
I've took a picture of the socket
socket pic
the error figures seems to reset everytime i reboot, it does look like a lot of errors?!
and my stats below (after 7 hrs)

To be honest, them stats look fine for the uptime
Ignore the Up HEX errors.

Any chance of getting a photo of the wires within that box? It may just unscrew.
You could try setting your line to standard ADSL (g.dmt) rather thanADSL2+. It may be better on your line and some routers allow you to select that setting.
Did you do the quiet line test? Dial 17070 option 2.
|
|
|
|
Yes i did the quiet line test which i posted.
my router is just the standard o2 supplied router so i dont think i can switch to adsl from adsl2+
the fact that its now sync at 7MB ish is in line with what estimates says so thats fine.
unless of course i could get more? but i dont understand the line stats whether it can give me more speed.
is it necessary to open the socket further to see the wires?
what am i looking for? and what does the wires tell me/u?
|
|
|
The speed looks ok and not really massive amount of CRC errors.
You tell me whats wrong with them?

I'm on O2 but use my old Netgear (O2 still in its box). I don't know if the O2 box can be overridden.
The 7 Mbps sync is in line with your attenuation. You have more CRC errors than I'd like suggesting noise on the line.
I was wondering if you had a poor connection or missing wire, but given that your phone works that seems unlikely (ADSL only needs one wire connected, albeit much degraded, phone needs both).
Consider RouterStats http://www.vwlowen.co.uk/internet/files.htm to monitor your line to see if a noise pattern emerges.
I switch my router off overnight.

Normal for O2 (or BE) with broadcom at both ends on ADSL2+ interleaved.
The O2 router (speedtouch) is just reporting the corrections, and its reported to have bugs in the display part too.
For comparison here's my stats, on slightly older firmware (BE) that doesn't try to predict (badly) potential speed:

I've took a picture of the socket
socket pic That looks fine. We see the external drop-wire coming in through the wall and it is directly connected to the NTE5A. You have no extension wiring at all. Am I correct?
There is no need to look inside the back-box (which, of course, is the domain of OR) but if you are really inquisitive and wish to satisfy John's curiosity, just undo the two screws, lift the front part out, take a photograph and carefully put it all back again!
