Sony VPCSA21GX Wifi
Searching for a new adapter is simple because the only thing you have to know is the operating system that is installed on your Sony VPCSA21GX. It will be easier to buy a new USB adapter and install it, than to replace any built-in adapter your laptop may have. A lot of newer wireless adapters are simply plug and 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 send and receive signals to and from your home network.
Symptoms the wireless card should need replacing
- The wireless adapter in your Sony laptop is unable to connect to the internet
- The wireless signal has trouble connecting every day
- The laptop wireless driver cannot be installed
