Im even using a D-link adsl filter for my D-link DSL-604GT which i am selling to buy a netgear modem which also comes with an adsl filter I have a question I know Broadband modem do sometimes affect the connection and speed of the broadband Is there such thing as a bad adsl filter? I know most people would say as long as the adsl filter work its fine But like broadband are there specific brand of adsl filter which is reliable and fast?	Ninjabear (2948)

I used to use DSE filters, and when we went to the hard wired filter i didnt notice much change, so maybe the dse ones are decent, tho not exactly cheap..	Dannz (1668)

Just under $14 ascent.co.nz have a Dynalink available (with tail), their $13 generic is out of stock last time I checked. Some ISPs provide these at $9.95 for their customers thou such as Telstra PDQ. In my experience if you are having issues with disconnection or losing connection, try to use all the cables from your BB modem supplies you incl its modem cable for the telephone jack. B/c you are using a non BT plug, you would need to use a line filter even when the phone is not being used in that room. The line filter accommodates a 2 wire style while a telephone BT is a 4 wire by the side it connects to your mode, could be why, dunno. I am experimenting as I don't use a phone in my room so I have used a dialup modem cable becos it goes from the modem straight to a larger BT plug, I get disconnections with my Linksys modem but I have yet to test the filter more thoroughly, it appears I don't get them with it. In my exp, with the dialup cable, I get page does not open, MSN becomes unconnected, I have to turn on/off the modem router and sometimes I need to do a system reboot. Sometimes I get this after some hours, sometimes after 15 mins. On my modem when this happen, the DSL light would turn off, I have 2 lights, one for DSL and the other for its activity. Both are off.

512395	2007-01-03 12:43:00	nope you only need a filter for the PHONE not the modem.....the connection thru the filter to the adsl modem...is just a 'dumb' connectoin as far as I understand and the connection to the phone thru the filter actually filters the adsl signal so that the phone doesn't get upset......	drcspy (146)

Interference with the phone is a secondary issue at best, if the adsl integrity of the line is adequately protected then the phone will also be protected as an incidental outcome. Most filters are adequate, they are very simple devices and not rocket science to manufacture. If in doubt, try feeding the phone through two filters in series, it won't hurt the adsl signal. Having said that, you get what you pay for, so buying the cheapest may not be the best idea. Cheers Billy 8-{)	Billy T (70)
512397	2007-01-03 23:36:00	Why are you selling your current modem? I been linked up to router today for around 2.5hrs. I sat here last 30mins and (continuously) surfing via webpages. I got disconnected. The DSL connection light was off and then blinking and the light for activity was off. I left it for 10mins and it connected by itself. Before I couldn't open webpages. My thinking is this is fishy. I will now grab a line filter off a phone and use it with my cable with my BB modem and see how it goes for a couple of days.	Nomad (952)

You can't use a filter with your modem, it doesn't need a filter! The filter is used exclusively to isolate your phone from the incoming phone line at ADSL frequencies. If you feed your BB modem through a filter you can expect performance to suffer badly, and that's provided it works at all. Refer to my previous post in this thread.

512399	2007-01-03 23:48:00	When I bought filters, DSE sold me Nokia ones from "out the back", they were not an officially stocked item (but the price was the same). They said that the ones on the rack were not as good as the Nokia, however as they now sell DSE branded ones I have no idea if they are the Nokia or not. I use a single Nokia in-line filter modified to filter the whole house "phone" line, with only the router connecting before the filter. Works just fine for me.	the godfather (11663)

You need a filter on each outlet if using the Telecom wired system. You cad have trouble if your wiring is a rats nest, and may then need an incoming line filter. Telstra's cable connection is something else, and does not need individual filters [here in Wellington].	PENTIUM (426)

Cheers Billy 8-{) :rolleyes: I mean I am using the filter but leaving the phone socket empty. So I am using the modem cable provided with my modem. Instead of the dialup modem cable which goes straight to a BT.	Nomad (952)
