Sony VGN-SZ770N Wifi
Finding a WiFi adapter is easy because the only thing you have to know is the current operating system on your Sony laptop. You are better off buying a common WiFi USB adapter and install it, than to replace any built-in adapter your laptop may have. Most USB wireless adapters are plug-n-play, in that you just plug it in the USB port and the OS will handle everything from there. WiFi, or wireless internet, makes use of a wireless adapter to communicate with your router.
Symptoms your wireless internet adapter will need to be replaced
- Your WiFi signal goes in and out during the day
- The WiFi adapter in your Sony laptop does not connect at all
- The WiFi adapter driver shows it as not installed
