You are better off buying a new USB adapter and install it, than it is to replace any type of OEM adapter you might have. Most USB wireless adapters are plug-n-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 a piece of hardware in order to talk to your home router. Buying a wireless adapter is quite easy because the only thing you have to know is the current operating system on your Sony laptop.
Major indications of a faulty WiFi adapter
- The wireless signal goes out randomly over and over again
- The wireless adapter driver cannot be installed
- The WiFi adapter on your laptop is unable to find a signal from your router
