If your DSL service does not require you to login using a username and password, then the mAX system will work with your DSL service.  If your DSL service is still using older technology known as PPPoE which requires you to login using a username and password, then the mAX system is not compatible with your service.

I frequently seen users use their provided dsl modem/router from their isp. They then connect their max system to that router. You can either put the max systems ip address into the dls routers DMZ or put the max in access point mode.
