Sony PCG-FX250K Wifi
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 system will install the drivers automatically. The WiFi in your laptop, if so equipped, uses a piece of hardware to send and receive signals to and from your home router. Buying a USB wireless adapter is quick and painless because the only thing you have to know is the operating system that is installed on your laptop. It will be easier to buy a new wireless USB adapter and just plug it in, than it is to replace any type of OEM adapter you might have.
Symptoms the wireless card is in dire straights
- Your WiFi in your Sony laptop will not connect to your router anymore
