A WL300N-USB driver is an important program for your Jaton laptop or computer, as it promotes correct functioning of your Toughbook device. Moreover, a driver can promote correct functioning of any other device, e.g., a printer, a scanner or a display card. As a rule, your Matrox DVI unit is already furnished with a CD with the proper 228PCI-Twin driver set. If the CD is lost, please take advantage of the Matrox DVI link for 228PCI-Twin downloading.
