Sony PCG-FX340P Wifi
It is cheaper and easier to purchase a new wireless USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. Finding a WiFi adapter is easy because all you need to know is what OS you are running on your laptop. The WiFi in your laptop, if so equipped, uses a piece of hardware in order to connect to your router and modem. Most USB 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.
Some warnings to watch for in a failing WiFi adapter
- Your wireless internet connection has trouble connecting every day
- The wireless adapter driver gives errors when installing
- The wireless adapter in your Sony laptop does not connect at all
