Here's the BT SpeedTest result from just now:

The trouble is, BT would claim that's acceptable.

I think you need to get on to IDNet on Monday, and get them to check things out.

Weird... Now it's holding up.

It just seems to be wildly fluctuating throughout the day...

I seem to remember that BT provides an ADSL username and password to troubleshoot speed issues - does anyone know what they are?

Glenn · Oct 24, 2009, 23:11:52

Can you download and run routerstats http://www.vwlowen.co.uk/internet/betatesters.htm to see if line noise is causing the problem?

Lance · Oct 24, 2009, 23:13:12

I think you used to need the username and password for a old version of the BT speedtest, but it isn't required any more.

I'm a Mac user, so I can't use it. Is there an equivalent? Earlier in the thread I posted some raw data from the router statistics, if that helps.

No there is nothing like it available, I tried to find something to use on my Dell Mini9 Mac. It constantly monitors your line sync and noise margin, Rik has found it useful in the past to isolate line issues. Is the line losing sync each time the speed drops, or just its PPP session, the router error log should tell you, as long as it doesn't reboot each time?

Sync and profile have remained consistent throughout. Do you know how to obtain the error log for a DG834?

Once you've logged into your router interface, I think it's somewhere like Router Status > "Show Statistics" Button.

LCP: Short for Link Control Protocol, a protocol that is part of the PPP. In PPP communications, both the sending and receiving devices send out LCP packets to determine specific information that will be required for the data transmission. The LCP checks the identity of the linked device and either accepts or rejects the peer device, determines the acceptable packet size for transmission, searches for errors in configuration and can terminate the link if the parameters are not satisfied. Data cannot be transmitted over the network until the LCP packet determines that the link is acceptable.

Can't answer why it's disconnecting, though. Have you checked the MTU?

If you power down and restart your router the date defaults to the time in line 1 above. After the router has connected, it requests the time and date from a time server and resets as in line 2 above. The router does not remember the time if it is turned off.

I believe that Netgears no longer log re-syncs, so you'll only see the PPP coming back up in the log. MTU wouldn't have anything to do with it.

Here's another BT test

Download Speed
1297 Kbps

Download speedachieved during the test was - 1297 Kbps
For your connection, the acceptable range of speeds is 600-7150 Kbps.
Additional Information:
Your DSL Connection Rate :8128 Kbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
IP Profile for your line is - 7150 Kbps

netgem21 · Oct 25, 2009, 14:11:12

Has anyone got any ideas on what I can troubleshoot at home before I call support tomorrow?

Sebby · Oct 25, 2009, 15:42:46

If sync and profile are constant, there's nothing more I can suggest.

What else do you think this could be? Issue with the router? Exchange? Filter? Contention at Exchange?

netgem21 · Oct 25, 2009, 18:20:24

Speeds are now consistently around the 200k region.

I can no longer use the BT speed test - it's completely useless. It didn't pass Test 1 saying 'No of threads are 4' (

) and it then asked me to change my router's login settings, so I opened a new tab in the browser. Went back to the BT tab and it refreshed the page and it now wants me to wait another 3 hours.

I don't know what to do... I can't live with an unstable connection like this.

If it's of any relevance, I have an independent ADSL line with no phones on it. Would I get better connection reliability without the microfilter? Also, could any of this be caused by line noise/poor quality wiring, etc...

I have been with IDNet for a couple of years and my connection has always been above 7Mbit - that's what's confusing me...

What's WBC? All I know is that my exchange's 21CN PSTN switchover target is in Q2 2010.
