Sony VGN-AR790U Wifi
It is cheaper and easier to purchase a common WiFi USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. 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 VGN-AR790U. 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, makes use of a wireless adapter to send and receive signals to and from your router.
Major symptoms the WiFi adapter will have to be replaced
- Your WiFi signal goes out randomly over and over again
- The WiFi adapter driver suddenly shows as uninstalled
- The wireless adapter in your Sony laptop is unable to find a signal from your router
