Hello,
I have an hp pavillion dv6-6c11nr Notebook that I recently downgraded from Windows 8 to Windows 7 Ultimate x64.
When doing so I re-formatted the harddrive and lost all drivers. I downloaded them one by one from the hp website (on another computer) and installed everything, but the only network adapter showing in network connection is the one which requires an ethernet cable. My wireless adapter seems to be "missing" somehow. In the device manager it shows Network adapters -- Realtec PCIe Family Controller (drivers up to date), and under Other devices--- Network Controller (no drivers installed)
The "internal network adapter" is ENABLED in BIOS.
