You must install at the bare minimum the motherboard chipset and the WiFi driver. You might also have to find HP's APP that turns on the WiFi card.
Many folk can't do this work (I can't because I would need the laptop or same model to write a step by step) and bail out with some USB WiFi.
I am fixing an old laptop for my dad to check his email on. I got it from work. It was brand new in the box but they were throwing it out because they were upgrading to new windows 7 pc's.
It is a HP Compaq NC6000. I installed windows 7 on it myself. I upgraded the ram from 512mb to 2gb. I bought a wireless card for it (hp w500 mini pci) and installed it. Windows automatically found the drivers and installed them. It says it is working fine however no wireless networks show up.
I am stuck. I have verified antenna connected properly. I uninstalled and reinstalled it. I tried downloading different drivers. I don't know what to do.
