Sony PCG-F650 Wifi
It will be easier to buy a new wireless USB adapter and install it, than to replace any built-in adapter your laptop may have. The WiFi in your laptop, if so equipped, makes use of a wireless adapter to send and receive signals to and from your home router. 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 laptop. A lot of newer 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 install the drivers on its own.
How do you know if your wireless card has gone bad?
- Your WiFi signal goes out randomly during the day
- The wireless adapter driver gives errors when installing
- The wireless adapter in your Sony laptop will not connect to your router anymore
