Hi, I recently installed Windows 8 Realase Preview but I can't really use it because I don't have internet connection.

Material : Hercules Wireless N USB Key (HWNU-300)
Realase Year : 2008
Recent Driver for Windows 7 : HWNU-300_V3.7
Statuts on Windows 8 : Plugged on USB but still turn off

Where can I get recent adapted driver for my wireless key please ?

You may not be able to. Many if not most manufacturer's of devices have not developed or at least released Win 8 specific drivers yet. The actual release of Win 8 is still 3 or 4 months away. I would suspect as time goes on more Win 8 specific drivers will be released.

Congratulation.
I installed driver HWNU-300_V3.7 / Uncompressed file : setupUSB : in "Windows 7" compatibility mode.
Wireless USB key worked after 1 reboot.
It's quiet unstable but it's enought in order to use Windows8 with internet.

It is possible new drivers will be released, or perhaps this device is old enough that the device manufacturers will not be developing Win 8 drivers.

It seems that this device, as well as other Hercules branded wi-fi products, is becoming outdated. After a quick search on the company, it looks as though it's gone in another direction, the multimedia one.

Those products are much more current than their networking ones.
