Windows 8 is not supported on some Pavilion G6 models (HP have no Windows 8 drivers for those models).
For supported G6 models only, you can download Windows 8 drivers from the HP website, but you'll need to know the exact model number of your laptop (look underneath it). Go here:
Hello,
i updated my hp pavilion g6 to windows 8 and now my wifi isn't working. how can I fix this?
I said previous to connect to www.hp.co.uk I have just realized you have no internet connection.The only solution is to buy a usb wifi dongle adapter.I have seen one advertized at Amazon for £3.49.You can connect to the internet with that.You can then download all the drivers you need from the website.
