Sony VGN-FJ270 Wifi
The WiFi in your laptop, if so equipped, makes use of a wireless adapter to communicate with your home router. Finding a WiFi adapter is easy due to the fact that all you need to know beforehand is the operating system that is installed on your Sony laptop. 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. A lot of newer wireless adapters are simply plug and 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.
General warnings of a defective WiFi adapter
- The laptop wireless driver gives errors when installing
- Your wireless internet connection disconnects and reconnects throughout the day
- The WiFi adapter in your Sony laptop does not connect at all
