Default ADSL connection dropping



Hi there.

My connection drops out every few hours for about 30 mins. I have tried a
new router, but get the same.

Are these setting to high / low? Any thoughts would be appreciated. BT
have been informed, but still waiting for an eng visit.

Thanks in advance.

Did you try changing your filters?

Tried 2 different filters, and also the unit direct into the main box - no
better.

this is on the limit (I assume the - sign is a typo)

http://www.yarwell.demon.co.uk/longlines.html has some ideas and
links.

try connecting directly to the master test socket.

Remove the front plate of the master socket. Behind which you will find
another socket.
Connect your modem to this using a regular modem lead (BT on one end RJ11 on
the other)
If it sync with better SNR margin, your internal wiring is to blame. Get a
filtered face plate either from a BT enginneer visit via your ISP, or DIY
from Clarity, or ADSL nation.

Looks suspiciously like a 3Com OfficeConnect if I'm not mistaken. Mine also
displays negative figures very occasionally (5 times out of 3000 samples)
when the noise margin is particularly poor.

Please report back on what the BT engineer has to say.

Using my extension wiring my downstream noise margin ranged from 9-14db I
still used to get regular failures - typically every evening when ADSL
usage is at its peak.

Connecting directly to my master socket and isolating my extension wiring
with a filter gives me a downstream margin of about 20db and a completely
stable connection.

So your issue is simple to solve. Get a faceplate filter from BT, Clarity or
ADSL Nation.
