I've got two internet connections. One is through a work network with a cable modem and series of switches, routers, etc. The other is simply an internet connection from a cable modem and a single Cisco unmanaged switch. My laptop can wirelessly connect to everything, but it can only connect to the work network when I give it a static IP. As soon as I try to obtain an IP thru DHCP on the simple network I get "Unidentified Network" - No Internet Access. Any ideas?
