The history of my problem is in an Apple discussion at http://discussions.apple.com/thread.jspa?messageID=3672296#3672296 Brief summary: I have 2 Mac OS X machines happy on a LAN, but cannot get an old OS 9.2 mac to join the network. TCP/IP seems to be set up right because the OS 9.2 machine connects to the internet at the Ethernet output of my modem, but not at any of the LAN ports of the router. (My OS X machines are happy with any of the LAN ports.) The OS 9.2 computer cannot see the router when the URL http://192.168.1.1 is given to the IE browser. The browser just hangs looking for it. (The OS X machines connect to the router's control panels at this URL.) Multiple cables have been tried (not a crossover cable problem). I have read the article http://www.macworld.com/2000/12/bc/01howtorouter/index.php and followed the steps (except the ones for setting up the router, since that is supposed to be done only once). Any suggestions?
