Nic Card

my XP internet just stopped all of a sudden. i checked, and there is no missing drivers, all are recognized. it sees the ip address, but still doesnt connect. lastly, i know the internet works because my ubnutu (linux) machine works perfectly. So recently i installed a nic card (and got drivers with linux machine). the card is recognized, but it always says “limited or no connectivity” and an error occured while assigning a network address. what is the fix to this (with or without nic card, i dont care) i just want my internet to work on my windows machine. thank you for all your help.
