BT 2Wire/BT2700HGV dropping connection

Evening all.

ISP: Demon Internet
OS: Windows XP Pro sp3

I have a BT 2Wire/BT2700HGV router running Singtel branded firmware, the router will drop connection within a few minutes of being on or sometimes it can be a couple of hours.

I have a spare Netgear DG814 (which used to be my original router) before I went WiFi on a few devices. The netgear performs fine and does not drop connection like the 2wire does.
The DG814 does not connect at the same speed the 2wire does, the Netgear has a lower connection speed.

Some details from the routers

When the 2wire drops connection, sometime I see a red light on the router, other times I do not.
Here is the error that is shown in the diagnostics
DSL Synchronization: UP
G.DMT Signal: UP
PVC Connection: Could not find an ATM circuit
PPPoA Service: Unable to connect to login service
PPP Authentication: -
IP Connection: An Internet address could not be obtained
DNS Communication: Unable to contact the Domain Name Server

I have tried setting the MTU to the same as the Netgear and still get the same issues.

When the connection is dropped(or get a red light) as soon as I plug in my Netgear the connection springs to life and stays stable.

I have 4 WiFi connected devices, Wii, 2xSamsung phones and a XP tablet.
I have 2 wired connections
All devices experience the same issues.

The router plugs into a BT master socket with a built in filter which has a CAT5 and a RJ11? connection on the face plate

Any ideas people?

Thanks
John

In the 2Wire try forcing it to use ADSL2 mode, rather than ADSL2+ which for your line stats may be less stable, than the slower mode. If that still gives problems force down to ADSL mode

The 814 will be slower as if memory serves me right, that is an ADSL only device

What does the full sync log page show? It has the last 20 events listed.

In reply to a post by MHC:

What does the full sync log page show? It has the last 20 events listed.

Can you point me in the correct direction for the location of the Log file?

The router has been stable for a good few hours today after I changed the Upstream MTU setting to 1475

I did find this log

Where do I find this setting in the 2Wire?

Try this link
http://192.168.1.254/xslt?PAGE=C_5_3

if version 6 firmware

Ian

I am on version 5.29.117.3 of the software and the link didnt work due not being on the same firmware.

home/xslt?PAGE=C_5_3 was where I would suggest ... but with V5 you may not find it!

Not haveing a v5 here I cannot check either and it is not in use in my other home - put a v6 in there now!

But if you can try <settings> <diagnostics> <dsl> - if it exists!


One of the best places to try for 2700 advice is: http://www.idnetters.co.uk/forums/index.php/board,25... several there know quite a bit about the v5 and worth asking for assistance from there.

Have you just changed provider as my 2wire did this as soon as i joined adsl24.
Just does not like the new kit for some reason

Similar problem 2 years ago. Although the 2wire seemed to be working (showing red light) the connection would drop. switch off at plug and reboot would solve for a while. IN FACT IT WAS THE 2WIRE POWER BRICK FAULTY. Usrd a new power supply (same output etc) and all good.
