Here's what I'm after: I want to avoid getting my TCP/IP settings by DHCP at work and home, but the networks are different (one is a 192.168.1.xxx subnet and one is a 192.168.0.xxx subnet) and have different gateways and DNS servers. Is there any way for OS X to automatically apply these, without me manually selecting a profile from network settings? i.e. when I connect to WorkWiFi, OSX assigns an IP Address, DHCP, DNS server, etc. When I go home and connect to MyHomeWiFi, OSX assigns a different IP Address, DHCP, DNS, etc.?
