It is possible there is no driver that will work. However, it is more than likely there is one,. You just need to be able to find it.
First try to install the Win8 driver
Device manager, expand the network driver item, right click on your device, Choose the Details tab
Choose Hardware ID under the Porperty drop down
That first line of characters is the hardward ID. Copy it to the clipboard
Do a Google search for that ID
Now you have to be partly detective and partly a cautious person. Try to find a device that fits yours.
Remember to set a restore point BEFORE you do any installs.
