Ahm guessing you're using Open Transport here, and haven't switched to MacTCP (classic networking)... Two possible points of failure... 1) Your internet connection isn't functional. This covers everything from the modem not able to completely initialize to being improperly provisioned (its MAC addess not being authorized, in your ISPs database, to talk). 2) An inability to obtain a proper IP lease by DHCP. Early versions of Open Transport, particularly those that work with OS 7, had very buggy DHCP Client implementations, making it impossible or very difficult to get a valid DHCP lease from most standard DHCP server implementations. About the only fix for this is to either upgrade your OS or get a static configuration from your ISP. First thing to do is to make sure everything is set-up correctly... 1. Make sure the TCP/IP control panel set to use DHCP. Under the Options button, TCP/IP must be active and *uncheck* Load Only When Needed. 2. Shutdown your Mac. 3. Connect the cable modem to the Mac. 4. Power-cycle the cable modem. Do this by unplugging it, NOT by using its power switch! Leave it unplugged for at least 30 seconds to a minute. This is to make sure it "forgets" its IP lease, the last MAC address it saw, and other parameters. 5. After plugging the cable modem back in, WAIT for it to fully synchronize with the cable system (all lights solid green). 6. Boot your Mac. [I recommend leaving the modem running 24/7. This way the modem is always synchronized before your other equipment boots, and DHCP lease is renewed on a timely fashion. Additionally, if the cable company's DHCP servers should die, you won't be stuck, in the short term, with no connectivity at all (until your lease totally expires).] After your Mac has finished booting, open the TCP/IP control panel and see if it has obtained a proper lease. If it HASN'T, obtain from your ISP a static setup - ip address, hostmask, gateway address, and at least two DNS addresses. (Note that the DNS addresses obtained via DHCP will NOT show up in your TCP/IP control panel - that's a bug Apple never fixed! They're there, they just aren't "visible".) If it HAS, use a ping/trace program to test your connection. (Things like AOL and Nav - are not test tools; they're like slapping a tomato with a baseball bat to see if its ripe!) See if you can ping yourself. If you can, then try to ping your gateway (CMTS/head-end router). If that works, run a trace to your DNS server. ...
