If the device is installed correctly and not showing any !'s in the hardware manager, double-check the drivers are up to date and not showing errors as Win 10 supposedly has a valid driver for that model (I think it should show as a Realtek driver for that Edimax).
If everythng checks out then maybe have a look at what 'ipconfig /all' shows from the command line.
As a last resort you could try downloading a Win 8.1 driver package for it, uninstall the device then install the driver in Win 8.1 compatibility mode.
