Sony VGN-B3XP Wifi
It will be easier to buy a new USB adapter and install it, than to replace any built-in adapter your laptop may have. WiFi, or wireless internet, uses an adapter in order to connect to your home router. Searching for a new adapter is simple because the only thing you have to know is the current operating system on your Sony VGN-B3XP. 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.
Red flags your internal WiFi needs replacing
- The WiFi adapter driver gives errors when installing
- Your WiFi in your Sony laptop is unable to find a signal from your router
- Your wireless internet connection goes in and out over and over again
