Query: Good for one PC, not useful for a network

I failed to read the description deeply enough and bought this before I figured out that it doesn't support PPPoE, which is used by most DSL providers. This is not a problem if you have one Windows box, because you can just run a software PPPoE client and all's well.However, if you have more than one device (e.g. your VoIP phone, or other computers), this will probably not work for you. I'm not sure about PPPoE software for Macintoshes, check for yourself.
