Perhaps the filtered faceplate is failing. It has been known.

I followed the instructions after confirming once again the chipset and apparently the router does not allow this.

In what way did it object?

Had you changed its IP addy from default 192.168.0.1? In which case you will need to modify instructions accordingly.

It did nothing. Didn't give me anything. I get a blank page on Firefox and a "page not found" on IE. Telnet didn't bring me any joy either, so I'm assuming it didn't work.

It could be that, but others in my area have bad speeds also. The notspot broadband site claims there is a big 'black spot' near my residence but I have no idea if it would even be linked in terms of the infrastructure.

I will certainly not rule out this possibility until I have done the test socket.

try following the instructions on Kitz for the other chipsets in case its not a Broadcom.

I didn't get anywhere. I did some more searching and apparently it is a Broadcom but in the latest version of the firmware (the one I'm using) telnet is not enabled. :/

You're clearly not daft, so I'm just checking a mistake most of us have made in the past - your OS is telnet-enabled? From Vista onwards, maybe even XP (I forget) the default is not.

Seems to be a pig of a problem .

Yes! Is telnet locked on DGN2200 router? It is!

First step.

Restart router and grab stats as soon as possible after that. If the Noise margin downstream is 11 to 13dB, then they probably have slowed the line down a little to improve stability, and it may be worth getting onto AOL support to ask them to speed things up, in geek speak 'can they lower the target noise margin'

Also monitor the noise margins over the course of a day, if rock solid and never alter probably not a line issue, if they vary a lot, then test socket which disconnects any other wiring in the property. An unused socket can still pick up noise, the wires act like a radio antenna.

On the neighbours, ask for their stats, if everyone is bad speed, but good attenuation it points towards something in the area creating RF noise e.g. a badly operating security light.

I did as you asked. Posted below are the typical results as of 20:00 today after monitoring since your post. The noise hasn't changed significantly (range of 11-12db) from the original data (11.8db).

ADSL Link Downstream Upstream
Connection Speed 2481 kbps 428 kbps
Line Attenuation 33.5 db 15.8 db
Noise Margin 11.8 db 11.5 db

As for your last point, would the source of RF noise not have to be very close to the telephone cable? The telephone cables around here are entirely underground. There is only one telephone socket in our residence. The telephone cable into our residence is located near possible sources of interference, but turning said sources off doesn't seem to do much. Sorry if I have picked this up the wrong way but I'm not clear on how radio noise works in this case.
