Wretched bandwidth -- 0.07Mbps

When I signed up for broadband in Nov 2011 my estimated speed was 1.5Mbps.
At the 14 day point it was measured at 1.25Mbps.
From https://portal.plus.net/my.html?action=data_transfer_speed my current line speed is 0.25Mb
From the BT Speedtester I get:
Quote
Download speedachieved during the test was - 0.07 Mbps
For your connection, the acceptable range of speeds is 0.05 Mbps-0.25 Mbps.
Your DSL Connection Rate :2.62 Mbps(DOWN-STREAM), 0.45 Mbps(UP-STREAM)
IP Profile for your line is - 0.14 Mbps

Other broadband speed testers rate my download bandwidth at about 0.125Mbps and my upload at about 0.35Mbps (?!)
The modem is an X2000 plugged into the master socket (behind the faceplate), with no phones plugged in anywhere and no extensions connected. The laptop (I've tried a few of them) is on ethernet to the modem-router. Nothing else connected to the modem is switched on, and there are no wireless connections.
Speed has deteriorated over the last few months to be pretty much unusable.
Next steps, anyone?

Re: Wretched bandwidth -- 0.07Mbps

I suspect that you have had a lot of disconnections and on one of them your speed was horrible
As you appear to be on 20CN it can take up to 72 hours for the profile to increase
As a start can you post your router stats - noise margin, speed and attenuation.
Also can you advise how your router is connected to the telephone system - at the master socket, another socket in the house, a long connecting cable, etc.

Re: Wretched bandwidth -- 0.07Mbps

Yes, I certainly get a lot of disconnections, which manifest as a DNS lookup failure. The router status pages often show me as still connected at the time, though not always.
The router shows a downstream rate of 2624 Kbps and an upstream rate of 448 Kbps.
These damned X2000's don't show the other statistics (I'll go give 'em a rubbish rating on Amazon in revenge) -- would the best way to get those to be to plug in a different router?
The modem's plugged into the master socket.
Thanks.

Re: Wretched bandwidth -- 0.07Mbps

It might be better to wait for a rep to pick this up as they should be able to get most of the information and you don't want to disconnect anything while you are waiting for the IP profile to change
Do you have any other telephone points in the property and is everything filtered - specially Sky boxes
DNS lookup failures where a retry finds it isn't a disconnection problem - I get this quite frequently and I have no idea why

Re: Wretched bandwidth -- 0.07Mbps

The line is also erroring quite badly:

Hmmm next time I'll give it a ping 8.8.8.8 to see if i really am disconnected. Rebooting the router seems to be the only thing that fixes it though.

Would that be an issue with the physical line itself?

Re: Wretched bandwidth -- 0.07Mbps

Potentially.
Errored seconds are often caused by internal wiring problems. However as you've said (and Jim missed) you're connected to the test socket.
I'd suggest swapping out the filter and/or router if at all possible to see if you see an improvement.
If no joy after that, it's a quick trip to http://faults.plus.net
I take it the drops shown in my graphs aren't all a case of you rebooting the router, or are they?

Re: Wretched bandwidth -- 0.07Mbps

I'd have a listen to your phone line first with a corded phone. If you can hear crackling or other noises you've got a dodgy phone line which you need to report to your line rental provider as a phone fault (don't mention the broadband otherwise you may get the run around).
It certainly looks like that the line's been under-performing since you joined as the Fault Threshold Rate reported is low. The line ought to be capable of a downstream sync of around 4.5Mbps.
Edit: Which version of the X2000 is it you've got?

OK -- well I have tried a couple of filters, and i'll see if i can borrow a router.
The drops could well be me rebooting, as I keep getting DNS lookup failures that I can only fix with a reboot. Next time it happens (which i guarantee will be soon based on past performance) I'll try an IP-based ping test to see if the connection is down and pull the log from the router to see if that's illuminating. With another laptop i was using OpenDNS though and that had similar issues so i sus[pect that the connection really was lost.
Thanks.

To test if you have an internet connection ping ntp.plus.net

Re: Wretched bandwidth -- 0.07Mbps

I just posted an edit as you both posted and I got delayed! Which version of the X2000 is that you are using?
