New computer can't access cable network

I have a new computer running Windows 98 and an old computer running Windows 95. When I connect the new computer to the cable modem and run Explorer, I get a message that it cannot display the page. I also do not get an IP address or default gateway from Adelphia. But if I attach the old computer to the cable modem, everyting works fine.

All of the Network Neighborhood settings match between the two computers.

 

Check your settings in Internet Explorer. Go to tools>internet options and the connections tab. Click the LAN settings button and make sure none of the boxes are checked for proxy server.

 

the computer name should be different, workgroup name the same

walk through the practically networked set up, see if there's a step missed or incorrect setting

can each PC ping itself at 127.0.0.1 ?

[edit: doh - i'm assuming a PC network - but sounds like you want each PC to access the internet separately? or is there a hub or router somewhere?]
