Hi everyone,

Two phones in the house (one is cordless in the main room) and sky connection.  In my office, broadband and office phone on one jack (with filter of course).  Anytime anyone picks up the phone (to answer or place a call) my broadband cuts out for about 1 min.  It does comes back, even if someone continues to use the phone.

I don't have filters on the phone in the main room or on the sky connection.  Could this be what is causing the dropouts?

I had a sparky install a new jackpoint a few months back but I don't this is related because I didn't notice the problem until weeks after it was installed.  It *could* be source of the problem, but wanted to see if anyone has had this problem.

Unless you have a central splitter hooked up giving you a designated jackpoint for your ADSL connection then *every* phone or device hooked up needs it's own filter. This includes phones, Sky, dialup modems and alarms. If they don't have a filter you will find your ADSL drops out just like you are experiencing.

Itis highly recommended approach on self-installs/connection only installs to place filters on every POTS device on the landline.
Unfiltered devices can cause interference as you have described.

Normally with modem packages, Xtra (other ISPs may have different amounts) sends out 2 filters...

Splitters filter all jacks bar your one for DSL and thus are generally easier to use if you have a managed alarm, lower than normal signal, or a large amount of POTS devices.

Cheers :)

Well, have got filters in all phone ports, but still have broadband dropping out whenever someone picks up the phone.  Damn.  Must be something in the wiring?

Try removing all devices bar the modem (try swapping the filter too) and add each device on to see whether it is a specific device/jack thats causing it.

How many devices do you have running on your line?

3 jacks in total in the house:

1. phone/ADSL splitter, into which is a wired phone and ADSL modem
2. Dick Smith DSE ADSL Line Filter BT and Sky TV
3. Dick Smith DSE ADSL Line Filter BT and cordless phone.

What i need to buy is a DSE ADSL Line Filter BT + RJ11 filter to replace the DLink and the methodically test as you say.
