I have addae extra photos
(LINK) and will make more sense of my at length description in previous post. I have a cordless phone which has always worked fine.( It is attached to the splitter the hub is conected to as this is my only socket)
Left hub conected overnight to test socket and tested this morning. The blue wire to the faceplate was effectively disconnected/isolated as I was plugged straight into the test socket. Recieved the following stats
Downstream 8,128 Kbps
Upstream 448 Kbps
Noise margin (Down/Up) 9.0 dB / 23.0 dB
Line attenuation (Down/Up) 36.0 dB / 19.0 dB
Output power (Down/Up) 19.8 dBm / 12.1 dBm
Running TB speedtester showed 6.1Meg down which is about double what I have ever got since I was connected in January
Detached the blue wire from faceplate pin 2. (This wire is part of the white line that runs from the single downstairs socket to the upstairs. Further investigation has found it just ends upstairs directly at one socket only but no plate at all yet so this line just ends dead) Anyway detached the blue wire and rerun test with hub pluged into faceplate, obtaining the following.
Downstream 8,128 Kbps
Upstream 448 Kbps
Noise margin (Down/Up) 9.3 dB / 23.0 dB
Line attenuation (Down/Up) 36.0 dB / 19.0 dB
Output power (Down/Up) 19.8 dBm / 12.4 dBm
Then I reconected blue wire to faceplate pin 2 as it had been as left by openreach/electrician and re run test with hub pluged into faceplate obtaining the following:
Downstream 5,120 Kbps
Upstream 448 Kbps
Noise margin (Down/Up) 8.4 dB / 22.0 dB
Line attenuation (Down/Up) 36.0 dB / 19.0 dB
Output power (Down/Up) 19.8 dBm / 12.3 dBm
Finally I disconected the blue wire and with the haub plugged into the faceplate obtained:
Downstream 8,128 Kbps
Upstream 448 Kbps
Noise margin (Down/Up) 9.2 dB / 23.0 dB
Line attenuation (Down/Up) 36.0 dB / 19.0 dB
Output power (Down/Up) 19.8 dBm / 12.2 dBm
So it seems that the attaching of the blue wire to the faceplate causes the problem?
