xbox wireless adapter

[frequency]

i wanna purchase the xbox wireless adapter cause i want the freedom to move my xbox around the house without the need of wires everywhere. i have a dsl router and a switch which i use to connect the xbox with a rj45 cable to transfer games via ftp. i heard somewhere that its not possible to connect an xbox wireless adapter if u have those dsl routers that has the phone line connected to it or something like that. i have a VisionNet model #708EUR. i know first if its compatible with the xbox wireless adapter b4 i tend to fork out the cash and buy it.
