Sony PCG-F640 Wifi

It is cheaper and easier to purchase a common WiFi USB adapter and install it, than it is to replace any type of OEM adapter you might have. Most new Wifi adapters are simply plug and play, in that you just plug it in the USB port and the operating system will take care of the rest. Buying a USB wireless adapter is quick and painless because all you need to know is the operating system that is installed on your Sony laptop. WiFi, or wireless internet, uses a piece of hardware to send and receive signals to and from your router and modem.

What are some indications that my WiFi adapter is almost dead?

The wireless adapter in your Sony laptop does not connect at all
The laptop wireless driver suddenly shows as uninstalled
Your WiFi signal drops multiple times during the day
