Sony VGN-SZ170P Wifi
It is cheaper and easier to purchase a new wireless USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. A lot of newer wireless adapters are plug-n-play, which just means that you only need to put the adapter into an available USB port and the OS will handle everything from there. The WiFi in your laptop, if so equipped, makes use of a wireless adapter in order to connect to your router and modem. Buying a wireless adapter is quite easy because all you need to know is the current operating system on your Sony VGN-SZ170P.
