Sony VGN-SZ120P Wifi
It is cheaper and easier to purchase a new USB adapter and install it, than it is to replace any type of OEM adapter you might have. The WiFi in your laptop, if so equipped, uses an adapter in order to talk to your router and modem. Buying a wireless adapter is quite easy due to the fact that all you need to know beforehand is what OS you are running on your Sony laptop. A lot of newer wireless 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 handle everything from there.
Hints of a deteriorating WiFi adapter
- The laptop wireless driver shows it as not installed
- The wireless adapter on your laptop is unable to connect to the internet
- The WiFi goes out randomly over and over again
