Sony VGN-FW375J Wifi
It is cheaper and easier to purchase a new USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. Most USB wireless adapters are plug-n-play, which means you simply plug it into a USB port and the OS will handle everything from there. The WiFi in your laptop, if so equipped, uses an adapter to communicate with your router. Buying a wireless adapter is quite easy due to the fact that all you need to know beforehand is the operating system that is installed on your Sony laptop.
Important signs your wireless internet adapter should need replacing
- The WiFi adapter on your laptop cannot see the SSID coming from your router
- The wireless adapter driver shows it as not installed
- Your WiFi signal goes in and out throughout the day
