How to connect phone and ADSL modem at the same time

cst1992 · May 24, 2014

Hi everyone.
I have ADSL broadband at my home and I have a UTStarcom WA3002G4 wireless router.
The thing is that whenever the phone starts ringing, I have to switch off the router, but if I have some download or so running, that's interrupted (I know about download managers, so don't tell me that).
How can I have a configuration such that I can use my phone and modem at the same time?
I bought an ADSL splitter, but it doesn't seem to work. I connected the "line" jack to one of the wall phone ports, the ADSL jack to the router, and the "phone" output to a landline phone, but the noise is still there.
I'd really like to discover some kind of main hub so that I could install this there and stop worrying about it, since I have multiple landline phones at my house, and I don't want to switch off the modem at a bad time.

Every phone needs to be on the phone side of an ADSL splitter/filter.

Most recommended is a master splitter, which goes where the phone line enters your house, then you run a separate cable to your modem. This can also significantly increase speeds if you've got old/bad wiring.

You need a DSL filter. For example, http://www.verizon.com/support/residential/internet/highspeed/troubleshooting/connection+issues/questionsone/88044.htm

Do you know how I can find where the line enters?
All I see are phone jacks in my house which I connect wires to.
How about I buy 3 filters for each landline phone in my house? Will it work? I really don't know how this is supposed to really work; all I understand is that the frequencies are different, and the splitter splits the signal in two.

One filter per phone definitely works. You sometimes get a speed boost with a master splitter, though.

If you've got an overhead line, it's pretty easy. If it's underground, look around the sides of the house for a conduit that goes up the wall and then goes into a box, then into the house. Exact construction depends on country.

I tried using it on the main phone that we use, and it was working, but some noise was still there.
Could my splitter be low quality, or is some noise all right? With the modem off, there's almost no noise.

Hmm. It could be a poor/bad splitter, though I doubt it. The phone is definitely on the 'phone' port of the splitter?

The wire coming from the jack in the Line port, the modem in the ADSL port, and the phone in the Phone port.
Unless it's mislabeled, that's how it should be.
