A lot of newer wireless adapters are plug-n-play, in that you just plug it in the USB port and the OS will handle everything from there. You are better off buying a common WiFi USB adapter and install it, than it is to replace any type of OEM adapter you might have. Buying a USB wireless adapter is quick and painless because all you need to know is the current operating system on your Sony VGN-A290. WiFi, or wireless internet, makes use of a wireless adapter in order to connect to your home router.
