Sony VGN-NR398E Wifi
WiFi, or wireless internet, uses an adapter to send and receive signals to and from your home network. It is cheaper and easier to purchase a new USB adapter and install it, than to replace any built-in adapter your laptop may have. A lot of newer wireless adapters are plug-n-play, in that you just plug it in the USB port and the OS will install the drivers on its own. Buying a wireless adapter is quite easy because the only thing you have to know is what OS you are running on your Sony VGN-NR398E.
Some warnings the wireless card needs a replacement ASAP
- The WiFi adapter on your laptop is unable to connect to the internet
- The wireless signal has trouble connecting every day
- The wireless adapter driver cannot be installed
