Highspeed Cable set up for 2 PC’s using

I have 2 computers, main one using Windows XP, 2nd one using Windows Me. I had internet using ADSL with no problems using a hub for the 2 PC’s. Switched to Cable today and main PC (windows xp) looked great with good internet connection. I later found that the 2nd PC using Windows Me is not connecting to the internet. I have confirmed with my internet supplier that 2 IP’s have been released to the account. I assumed all settings would be identical from ADSL to CABLE. Anyone have any idea’s? Thanks
