Sony VGN-FW480J Wifi
WiFi, or wireless internet, makes use of a wireless adapter in order to talk to your router. It is cheaper and easier to purchase a new USB adapter and install it, than to replace any built-in adapter your laptop may have. Buying a USB wireless adapter is quick and painless because the only thing you have to know is what OS you are running on your Sony VGN-FW480J. A lot of newer wireless adapters are plug-n-play, which means you simply plug it into a USB port and the OS will handle everything from there.
Key symptoms of a barely functioning onboard WiFi
- The laptop wireless driver cannot be installed
- The WiFi adapter in your Sony laptop is unable to connect to the internet
- Your WiFi signal disconnects and reconnects all the time
