Hi Eric
I think I have made some progress on this problem.
I do not have a master socket in the house but I have 4 normal sockets in different rooms. 1 with the Netgear and the other a BT Diverse 4016 base station 1 handset (2 others handsets are though the house) the other 2 sockets are unused.
This has been changed by BT as a result of continuously notifying faulty line.
A BT engineer has change the system to include an NTE5 faceplate in the office. The Netgear is plugged directly into the NTE5. The Dect phone is still attached through a microfilter on another phone point.
I took your advice and tried an old Vanguard phone in place of the DECT but the results were inconclusive however it did confirm that the RingWIRE is still connected.
The current router stats are as follows:
ADSL Link Downstream Upstream
Connection Speed 1152kbps 288kbps
Line Attenuation 53db 15.5db
Noise Margin 25db 23db
I have now much more margin so my line should now support a higher connection speed, whilst having a more stable service. However I suspect that the speed I am getting is programmed (or wired) into the DSLAM. How do I get Pipex my ISP and/or BTw to change this top limit. I am currently on 1Mb because when they upgraded everyone 18 months ago this was my maximum attainable speed.
Any comments would be appreciated.
