adsl problem with BT
« on: June 01, 2009, 06:15:29 PM »

PLEASE HELP
I have problems with BT my stats are as ;-
Line state
Connected
Connection time   0 days, 15:25:36
Downstream   1,024 Kbps
Upstream   448 Kbps
ADSL settings
VPI/VCI
0/38
Type   PPPoA
Modulation   ITU-T G.992.1
Latency type   Interleave
Noise margin (Down/Up)   12.6 dB / 20.0 dB
Line attenuation (Down/Up)   47.0 dB / 26.5 dB
Output power (Down/Up)   15.9 dBm / 11.8 dBm

As you can see results are hopeless. in the past I've had connection speeds of 4840 kbps. throughput of 2.3Mbps
Bt maintain that i have a conection and 'put up and shut up' They are now charging me £240 for reporting a fault
and niether calling or phoning me and certainly not testing my line from the house.
ANY HELP will be welcome

Hi and welcome

There are several things you can do to home in on the cause of the low connection speed. Have a read of this and the associated pages. The single most useful part is to connect your router to the test socket, which completely eliminates your internal wiring from the connection. Also, it can be very helpful to install Routerstats if it's compatible with your router.

Just to give you a couple of clues:
1. The below-normal downstream output power suggests poor internal/extension wiring or equipment.
2. The high SNRM suggests there have been problems causing the BT DLM to increase your target SNR to 12db (from 6) in order to overcome interference/instability.
