BT Broadband signal keeps dropping

[LTGoldman]

Hello BT community,

I have BT Broadband and the signal keeps dropping.  For your information:

• I am using a Draytek 2850N with firmware version:  3.6.2_2471201
• I am not sure whether the line is ADSL or ADSL2+
• The exchange is Chobham and has exchange code:  THCH
• I am 1.2 miles from the exchange

The symptoms of the problem are simply that we loose the signal and cannot browse the web.  I have bought a brand new ADSL Filter and the router itself is brand new (replacing the BT Home Hub 1.x).

The strangest thing is that when the connection drops I can get it back by dialing out on our telephone which used the same line as the broadband and after a few seconds of listening to the time (I dialled 123) the router re-synch's if you leave the router to do this on it's own the connection does not reform; which I think is quite weird.

If you telnet onto the router and run log -wt I can see the following:

5:56:13.150 ISDN1<<<<PPPoE (WAN-1) Len = 45
    Protocol:CHAP(c223)

Can anyone tell me if this is BT's problem as I have replaced all of my kit.  Coult it be BT's NTE or even their network?

Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal

try this link as well as it may also help you http://forumhelp.dyndns.info/speed/speed1.html

your line length is 2.2km from the exchange

I have done the quiet line test and there is a slight hissing and crackling noise.  There is one master socket with a microfilter which goes out to the phone and router there are no other line extensions or phones.  The master socket is not one that has a test socket so cannot try using the alternate socket.

you need to get the line noise fixed as that is affecting your broadband phone BT Faults on 151 and report the line noise but do not mention broadband in the call once the noise is resolved tnen your broadband will improve
