Well the BT engineer arrived at 9.15 this morning and has just left:
He found a bad connection at one of the line boxes in the street, after he remade the connection my sync speed immediately jumped up to 7616kbps.
Latest test on speedtester showed:
Test1 comprises of Best Effort Test: -provides background information.
IP profile for your line is - 135 kbps
DSL connection rate: 448 kbps(UP-STREAM) 7616 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 100 kbps
And the router is showing
ADSL Link Downstream Upstream
Connection Speed 7616 kbps 448 kbps
Line Attenuation 29.0 db 16.5 db
Noise Margin 15.0 db 23.0 db
The Noise margin has been 14.8 to 15.0 for the last 10 mins.
So now just need to wait a few days for the bras ip profile to reset.
Well done to BT very impressed with the service.
