Hi:
For the g6-2244ca...
It can have one of two wireless cards, so you will have to post the hardware ID for the Network Controller device so I can tell which model it is.
If you do not know where to find the hardware ID, please read the guide at the link below.

Now for the rest of the drivers...
First, install the AMD chipset driver and reboot. First file listed.

Try the graphics driver from the HP Probook 6475b
Then you can use the rest of the drivers and software from the g7z-2100.
