DSL Connection Problems - Help!

I have a problem connecting to my ISP DSL account which started recently. I have spoken with my ISP who were as helpful as they could be, considering that they did not supply the router or the telephone line.

Up until 3-4 days ago there was no problem. I've only ever had a few short periods of no service over a 4-5 year period with my ISP Demon. Now I cannot get connected at all.

The phone line works fine. Demon have checked that there is no problem with the network, line, exchange and equipment.

I have a Belking wireless router feeding 2 directly connected PCs and a couple of laptops. I've tried another (Speedtouch 716WL) router on the line also but that doesn't connect me either.

I've tried connecting with the other PCs and laptops - these don't work either; which also rules out any software / virus issues that might have been affecting any of the PCs.

I've tried connecting to the test account as per my ISP's instructions - still no joy.

I've tried using another microfilter and cabling into a different phone socket - still no connection.

Normally the common suggestions like checking wiring, etc in the house would be looked at but as it has all be working for so long I can't imagine there is a problem there.

The only remaining possibility I can think of (cluthcing at straws!) is that I did move my phone line provider from BT to Talk Talk last month but the line / services remained the same and this change happenned 3 weeks ago so I can't see a reason why it would work fine until now.

I would really appreciate any suggestions / past experiences from anyone that might help here.

Some line statistics from your router would be a starting point to see if you have any connection at all.

Talk Talk are well known for slamming (moving connections without consent) so it could well be possible that they've moved you to their BB kit aswell as the phone. If so it is well documented that it's a royal pain to get back and will cost you money.

It could well be that they(talktalk) have put your line on their LLU which means that you cannot have broadband services from any other isp, so if you want talktalk for your calls & line rental you will have to also have their dire bb service if you want bb,unless you ring bt and ask for return to donor if this is the case your are now Fully unbundled FMPF full metallic path ,one of the joy's of being with talk talk, if you wanted there line rental rather than bt's then this would give them the nod to llu it

Thanks Tommy45.
I spent a long time on the phone to my ISP (Demon) who carried out tests and they say there is no problem with the path through the network and BT exchange equipment.
If Talk Talk had moved it over to their own equipment would this not have shown up when Demon did the tests. Also I know that my local BT exchange has not yet been unbundled, I doubt if I would be able to get the full BB package. Would Talk Talk not have needed a MAC code from Demon to transfer the service?

Just spoke to Talk Talk and no surprise they of course say that there is no fault on their service.

What kind of statistics do you mean and how do you get these?

When I spoke with my ISP (Demon) they say the tests they carried out showed that there was no problem with the DSl path across the network and through the BT exchange and equipment and that the line was still capable of a DSL connection.

Ok, The attenuation figures are as follows

Upstream Downstream
Noise Margin 27db 10db
Ouput Power 12dbm 20dbm
Attenuation 6.5db 13db

Does this mean anything to anyone?

It means you are connected, you have a short line, and your sync speed could be a lot better. It doesn't really confirm whether you are connected to Demon or Talktalk however.

any ideas on how I can find out?

I think you need to check the router logs to see if and how the connection is set up.
