All,

I was in my roof space over the weekend and I noticed that the cable from the demarcation point of my house first goes into my alarm and THEN into the master socket. (This was like this when we brought the house, I have only just noticed. The alarm is not monitored but is configured to call my cellphone when it goes off).

I have always had slow ADSL (1.2MB downstream but 800k+ up) and wondered if this could be related to the way the cabling is done?

I am unsure of my distance to the exchange, I am in Ranui and I think I am on a Massey exchange. ISP is Vodafone and I am scheduled to be part of the Red network this month.

Many thanks!

Ranui is not that close to the Massey exchange, but close enough to get better than 1.2 down. If you have a monitored alarm (includes self monitored), then you should have had a full install. I can assist with sorting out your cabling and installing a master filter if needed. Can also pretest to see what speed you will achieve before starting such work.
PM me if your would like some help.

This can definately cause issues. Odds are that even if you don't pay for monitoring the alarm will still be regularly "phoning home". This was the standard way of wiring an alarm (to try and make it as tamper proof as possible) but unfortunately it means that if you're using ADSL you really do need to have a master splitter fitted or bypass the alarm wiring if you will never use it.

Just an update to this (and to move attention away from the current iPhone frenzy!). I contacted 'coffeebaron' and he came around and did some tests, and found that my current shockingly bad transfer rates (modem was connecting at 200k per second!) could be fixed.

After coming back the next day and cabling from the demarc to a new socket with build in splitter, I was very pleased to see an increase in speeds, the modem was now connecting at 3940k down!

The main cause seemed to be a combination of the phone entering the alarm fist, and also the use of untwisted cabling, all of which was replaced with CAT5 cable.

Many thanks to 'coffeebaron' for his work, it was very professional and he did a fantastic job. Now I can surf the 'net at a decent speeds! (speedtest results to come...)

The alarm causes interferance every time, even when its just listening without trying to call. Alarm guys these days normally seem to carry splitters with them and should install one if you ask about broadband.

Time to find a new industry!
