I'm thinking about building a wireless load balancer (if that makes sense). For example, the first wireless card will accept all connections for ip 192.168.1.1 and the second card will serve requests for 192.168.1.2. I know that I can assign both IPs to a single card and all requests will be served by a single wireless card. Would it be better (more bandwidth, more stable connection, etc?) to have two physical cards instead?
