Sony PCG-GR270K Wifi
Buying a USB wireless adapter is quick and painless because all you need to know is what OS you are running on your laptop. Most new Wifi adapters are simply plug and play, which just means that you only need to put the adapter into an available USB port and the OS will install the drivers on its own. You are better off buying a new wireless USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. The WiFi in your laptop, if so equipped, uses a piece of hardware in order to connect to your home router.
