Sony VGN-AR190G 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. You are better off buying a common WiFi USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. The WiFi in your laptop, if so equipped, uses an adapter in order to talk to your home router. Finding a WiFi adapter is easy because all you need to know is the current operating system on your Sony VGN-AR190G.
Main clues the WiFi adapter is on its last leg
- The wireless adapter driver shows it as not installed
- The WiFi adapter on your laptop cannot see the SSID coming from your router
- The wireless signal disconnects itself during the day
