- satysin 11y agoI just use the driver supplied via Windows Update. It works out of the box but there is also a driver update available if you manually upgrade the driver from device manager. Card is Intel Ultimate-N 6300 AGN Driver is 15.18.0.1 Date 30/04/2015 The only drivers I had to install were for the SD card reader (Ricoh) and an update for Audio from Lenovo as it is a later version than from Windows Update for some reason.
