Sony VGN-FZ470E Wifi
Most new Wifi adapters are plug-n-play, which just means that you only need to put the adapter into an available USB port and the OS will install the drivers on its own. 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 Sony laptop. The WiFi in your laptop, if so equipped, uses an adapter in order to connect to your home network. It is cheaper and easier to purchase a common WiFi USB adapter and install it, than to replace any built-in adapter your laptop may have.
Indications of a bad wireless card
- The WiFi adapter in your Sony laptop does not connect at all
- The wireless adapter driver suddenly shows as uninstalled
- Your WiFi signal disconnects and reconnects every day
