DriverLoader is available from Linuxant. DriverLoader can be downloaded here.
Instructions for installing DriverLoader can be found here.
NOTE: Linuxant recommends installing the wpa_supplicant package along with DriverLoader. CDRouter however, uses it's own internal supplicant for managing WPA, and does not require wpa_supplicant. As a precaution, we recommend removing wpa_supplicant from your CDRouter system to minimize potential issues and conflicts.
