before you buy a new card try the following:

For Win XP

start -> run -> cmd /k ipconfig/all then press enter. What ip address do you get?

for win 98

start - > run -> command (a black boxed windows should open) then type ipconfig/all and press enter - What ip address do you get?

if its a 169.xxx.xxx.xxx or then your netword card is working and the problem could be with the ethernet port on the cable modem.
