It will be easier to buy a new wireless USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. Most USB wireless adapters are simply plug and play, which means you simply plug it into a USB port and the OS will install the drivers on its own. WiFi, or wireless internet, uses an adapter in order to connect to your home network. Searching for a new adapter is simple because the only thing you have to know is the current operating system on your Sony laptop.
Major clues your internal WiFi will need to be replaced
- The WiFi goes out randomly throughout the day
- The WiFi adapter driver shows it as not installed
- Your WiFi on your laptop will not connect to your router anymore
