Sony VGN-NS190J Wifi
Buying a wireless adapter is quite easy because all you need to know is the operating system that is installed on your Sony laptop. It will be easier to buy a common WiFi USB adapter and just plug it in, 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 system will install the drivers automatically. The WiFi in your laptop, if so equipped, uses an adapter to communicate with your router.
What symptoms are present when the WiFi adapter is about to fail?
- Your wireless internet connection drops multiple times during the day
- The wireless adapter driver suddenly shows as uninstalled
- The WiFi adapter on your laptop is unable to connect to the internet
