Have an old hp Nc4000 and replaced the Hard drive after it failed, running XP pro all up and running and can connect to web thru Ethernet connection but wireless is causing problems, connects to modem easily [currently have another laptop connecting to web wirelessly without problem] but gets stuck when ''acquiring network address'' , anyone know what boxes I have to tick to solve this one? Seems it does not have IP address and cannot remember how I solved similar problem last year.
