Hey...Sarah is Back!
How could I control the shared internet access thru wifi connection? Can I get control of it?
Your question is oddly phrased. If you are asking can I share internet ? Yes you can via a router. If your asking can I share the allocation of bandwidth to those sharing an internet connection -- no you cannot via a domestic type router. If you are asking about the Internet Connection Sharing feature of Windows XP, you should repost more clearly.
