Network down when use phone, how to fix?

[PeopleFun]

Hi, I'm using SBC as provider, and Dlink 604 router (wired router) for my network. I have a phone AT&T 2.4gb cordless phone. I set up like this

- dsl line to router
plug - 2.4gb phone
- 900mhz phone

before, I use the 900mhz is ok (when I'm talking, dsl never disconnected). But when I plugin the 2.4g phone, whenever I use it, the dsl router disconnected (I can't browse any more) until I off the phone.

What's the problem? how to fix it?

My 2Ghz phone kills my wireless connection in my house. Do you have wireless in there somewhere?

If you are using an 802.11b wireless connection. The 2.4ghz phone will interfere. 802.11b runs at 2.4ghz and of course a 2.4ghz phone runs on the same frequency (thanks FCC).

Since you stated that you have a wired router, then your problem is most likely a DSL filter configuration issue or a bad DSL filter.
