My Opinion

[#1]

Use one of the laptops to scan for any other local networks (try that at some point with your router off, not necessarily right now) and pick a channel well away from anything you might find. Might be worth doing that check several times over the next few days at different times.

If you are able to look at your router configuration, using wireless, there cannot be an encryption problem.

[#3]

Didn't suggest there was an 'encryption' problem, want to check there isn't a security or interference problem.

Line Status from the Belkin G
I have changed my Router

[#5]

There's a definite improvement there. How are you connected etc?

[#6]

I am still conected to the test socket, and by the way this morning I was going to take some pictures of the socket next to the NTL box, and I noticed that one of the wires
conected to the main BT socket was loose, so I have disconected the whole thing all together, so there is no point anymore on me taking pictures of it, as there is no
conection between the two....But yes there is some improvement.

[#7]

Well there might still be a point to taking some pics, we may be able to give you some more clues/info about your wiring for future reference. What's the latest stats like?

[#8]

OK Anotherone I will get the done regardless... Here are the latest stats
ADSL Internet Settings
Downstream                  Upstream
1856                                        448
Noise margin
9.6                                       12.0
Output power
16.9                                      12.4
Attenuation
63.0                                      31.5
The noise it's still high, cos I am sure I have seen it on 7.something before, but the download speed there is deffenetly some
improvement and I belive it has to do with the change of router. Infact, the problem where my internet conection drops is still
happening the only difference is that now I am able to disconect the router through the browser not like with the Voyager 2091,
which as you all remember I had to diconect and reconect manually, cos' I couldn't do it through the browser... I will take thoes
pictures some time this afternoon I have some visitors comming shortly for a couple of hours, and I will also post you some more stats.
See you later and thank you for your help!

OK then, I'll look out for your post.

Ok ... This is the picture from the inside of that extension socket next to the NTL box.
Don't forget this extension socket is not connected anymore to the main BT box.

[#11]

It's a bit difficult to see which wires are coming out of which cable as they bunched together. Do you remember which colours you disconnetced from which terminal?
Also have a look at the rear of that bedroom socket and the wiring there - picture again would be useful.
