Most of it works just fine. Yeah its nice to have a modem and wireless gateway all in one but it doesn't always work with my setup.I have a voip phone. It is the only thing plugged into the modem. Everything else is wireless. Whenever the phone rings all wireless connections are dropped. I would assume this to be the case with any wired connection that causes a jump in bandwidth use. This is extremely obnoxious! I'll probably send it back and go back to my old modem and router setup.
