if you tried the drivers from the manufacturer's website and it didnt work you have a few options:
1) use the system restore partition to factory restore the computer to a working state
2) install a different lan/wireless adaptor in the computer.
3) contact HP for tech support
Would you be willing to tell me how to use the restore partition? In "RECOVERY (E " I have HP_WSD.dat, when I open it win 7 cant open it. I have a folder called restore, in that folder, there is _CNBRP.FLG, (error when attempted to open) HPRP.txt, lang.cfg, and TypeList.txt
