Sony VPCF12CFX Wifi
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. WiFi, or wireless internet, uses a piece of hardware in order to connect to your router. Most USB wireless adapters are plug-n-play, which just means that you only need to put the adapter into an available USB port and the OS will handle everything from there. Buying a USB wireless adapter is quick and painless because the only thing you have to know is the operating system that is installed on your Sony laptop.
Simple signals the wireless card should need replacing
- The WiFi goes out randomly during the day
- The wireless adapter driver gives errors when installing
- The wireless adapter in your Sony laptop cannot see the SSID coming from your router
