Both Windows 7 drivers for the Sierra Wireless GX440 are not configured for Windows 7. On attempting to install them we get the error “The INF file you selected does not support this method of installation”.
Try device manager>USB>update driver software>browse my copmputer>let me choose>have disk>browse to .inf file>click or( double click) the.inf file and see if it will install.
