Sony PCG-FX390 Wifi

Buying a USB wireless adapter is quick and painless because the only thing you have to know is what OS you are running on your Sony laptop. It will be easier to buy a common WiFi USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. The WiFi in your laptop, if so equipped, uses a piece of hardware to communicate with your router. 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.

Major clues your wireless internet adapter is failing

The wireless adapter in your Sony laptop is unable to find a signal from your router
