Fair enough - the last Telstra tech we had here described them that way and indicated the junction box down the street was full of water (which he had to empty!) last time we had problems! > If you are getting interference on ADSL there are a number of sources for > interference. > > 1. Your filter that should be between your phones and the line where the > modem etc are connected. We have tried a different brand of ADSL filters (some Telstra ones) individually in place of the D-Link ones but we can't have any connected at all in order to get the ADSL modem to maintain a connection. The problem started with the ADSL connection dropping out whenever we made calls on the phone, but progressively got worse to the extent that we have to disconnect the phones and filters entirely. When we do plug a phone in and try to make a call, we can hear static and noises on the line for 10 seconds or so then it goes away - it sounds like it may be the ADSL modem trying to negotiate (whistles and beeps a bit like an old analog modem), so perhaps all of our filters may be stuffed after all? Not sure how that could have happened as they have never all been plugged in at the same time. > 2. Your equipment ( Modem, Router etc ) We have a spare ADSL modems at the moment - a SpeedTouch in addition to the D-Link and both of them display the same problem so I don't think it is this. > 3. The exchange interface equipment It sounds like it is either this or... > 4. Possibly an insulation problem with the line. ...perhaps this. We are a bit scared to call up Telstra to investigate the problem for fear of them saying that we are actually too far from the exchange still after all and they can't guarantee a reliable connection! Are we being silly?!! Yes okay - I guess I should call them up on Monday to investigate! :-] > Typically the filters are el Cheapo versions with an electrical " T " shape > instead of an " H " shape.

Lightning in an underground cable ) Ah, sounds like a distinct possibility - can't remember if we had a lightning storm that coincided with the line going bad but entirely possible. > And , by the way, just because your Mac performs Ok at a place like Curtain > does not mean that the Mac is OK. The thing is the Mac works fine when I disconnect the D-link and plug in the SpeedTouch instead here at our house, so it does seem to point the finger at the D-Link modem in the case of the DHCP issue. > Short line connections can hide the problem I see - that would explain it. > I suggest you start by checking the filter. > Martin, feel free to mail direct Thanks Bob - we appreciate your advice. It's great having an ex-Telstra guy like you on the list to tap into! :-) -Mart > Bob Howells -------------------------------------- Martin Hill mailto:[EMAIL PROTECTED] homepages: http://mart.ozmac.com Mb: 0417-967-969 hm: (08)9314-5242
