Sony VGN-SR390P Wifi
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 much simpler to buy a new wireless 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 means you simply plug it into a USB port and the system will install the drivers automatically. The WiFi in your laptop, if so equipped, uses an adapter in order to connect to your wireless router or modem.
Key symptoms of a defective wireless card
