I have purchased 2 different wired DSL routers from Fry's and my Mac G4 OS X 10.4.11 will not recognize the IP address of either router. I have called their respective tech support services and gotten no relief. One actually said that my computer has the wrong IP address. Is that even possible? Unfortunately, the other computer that I want to put on the network is a PC, but is a work computer and work will not let me have the access code to upload anything. What is the problem? Thanks.
