Re: Low download speed

Hi Jojo
I left the router in the test point for the last 3 days.  I have done a speed test today at 18.00 as below.  Can i now take the router out of the test socket(The other half is moaning at me as i have the cat5 cable running down the stairs) Grin

Re: Low download speed

I suggest leaving the router in the test socket until Jojo has had a chance to check your connection again tomorrow.
It looks like your sync/connection speed is dropping again causing reduced speeds. Without router stats like those you attached in reply #2 I can only guess the cause of this will be target noise margin increasing again, potentially indicative of a problem.
If you want to post router stats there is no need to attach an image, it's usually easier to press the left mouse button while you drag the mouse over the page entries from left of Uptime to right of the HEC Errors value, then right-click in the highlighted area and select Copy, right click in your reply post and select Paste.

Re: Low download speed

Yes, that's much easier to read.
I think these show your target noise margin (SN Margin) will have been increased by the DLM at the exchange to 15dB (the maximum on maxDSL). At the moment your noise margin is well above that target value, suggesting the source of noise could be intermittent. Do you have a feel for how noise margin varies through the day? Recording the history of this using RouterStats can be helpful. The full version of RouterStats works out-of-the-box with the TG585, just select the ST585 v6 or v7 radio button (it works with the v8 too) and enter the admin login information. A guide to configuring RouterStats is given in this post.
The CRC and HEC Error counts shown for 1¼ days connection represent significant rates even now - whilst plugged into the test socket. This suggests the source of the problem is not related to internal wiring however I suggest you remain in the test socket over the weekend.

Re: Low download speed

Hi there,
It looks like it's stayed connected solidly over the weekend, could you try disconnecting and reconnecting (via the router's interface - don't just pull any cables out or turn the router off as it'll look like a line fault if you do that) and see if the profile improves at all?

Re: Low download speed

OK, so i disconnected from the internet and then reconnected using the router interface at around 19:00 hours.  The stats just after that are as below

Re: Low download speed

Well the profile's updated recently to 3000 so should be performing alright, though if your sync speed stays where it is (or ideally raises slightly) your profile should uplift to 3500 though the SNR is quite high. The connection is fairly stable so an SNR reset might be possible, though that'll reset the training period - it should retrain at a faster speed with a lower SNR though.

Matt
Not sure what you are telling me regards the figures, but initially when Jojo reset the S/N i got the results as in reply # 11, but since then it seems to be gradually slowing down again.  I have just run a speed test again as below at 16:55.  Can i now take the router out of the test socket as i don't think the problem is in the house wiring?

Re: Low download speed

I think that should be fine though you may lose a bit more speed. I'm not too sure why it's dropped so much since the reset but there must be something going on for the profile to waver like that, the only issue is that the speed you're getting currently is regarded as absolutely fine by BT so it's unlikely we'll get any faults accepted.
It should be interesting to see what difference there is on the line with the internal wiring in the equation though.

Re: Low download speed

Well i thought i would leave this a bit to see if things improved.  Having done a speed test it appears not to be.

Re: Low download speed

Is that with the router plugged into the test socket or a normal socket?
The current sync speed is very low again, looks like line conditions were noisy when re-sync occurred. Did you initiate re-sync or was it a connection drop?

Re: Low download speed

Thats with the router back in its normal socket.
Did not re-sync so must have been a connection drop

Re: Low download speed

Your sync speed appears to be significantly lower where it is connected at the moment than when connected to the test socket.  Really you should aim for your line speed estimate which is 5000kbps.  Can you reconnect your router to the test socket so that we can re-check the sync speed there?  I think you have an internal wiring issue.

Don't understand what you are telling me re the sync speed!
How do i aim for 5000kbps?
Have reconnected the router into the test socket with the following results
