I have two wireless ADSL routers sitting right next to each other, each with his own internet connection. I'd like to be able to connect to a computer that is connected to router A from a computer that is connected to router B, while keeping both routers internet connection individually. i.e. If computer A is connected to router A, it will use router A internet connection, and a second computer, call it B, will be connected to router B, and will use router B internet connection. Is this possible?
