I have an AirPort Express and Comcast High Speed Internet, and it's a dynamic IP, or so the guy who set it up told me. I found my range of IPs on a WHOIS site and was wondering if I could modify AirPort to lease them to users instead of sharing the same one. Whenever I type in my range in the AirPort Admin Utility thingy, it says "Sharing a rance of DHCP addresses requires the base station to be configured using static IP addresses". Is there any way I can use all of my IPs? The reason why I want to lease several IPs is because the coverage in my house shrinks and the internet becomes slow whenever I have guests and the rest of my family comes here.
