Hi Tashee, Welcome to the forums, Looking at the Sony website I only find
drivers for 64bit
Sony eSupport - VPCEE21FX - Support ,Have a look in the device manager ,go to the network adaptor ,right click on it and select "update
driver" see if windows update will find a driver for you

Have a look here also
