Sony VGN-NS290J Wifi
You are better off buying a new USB adapter and install it, than it is to replace any type of OEM adapter you might have. The WiFi in your laptop, if so equipped, makes use of a wireless adapter in order to connect to your router. Buying a wireless adapter is quite easy because all you need to know is the current operating system on your Sony VGN-NS290J. Most USB wireless adapters are plug-n-play, which means you simply plug it into a USB port and the operating system will take care of the rest.
Major symptoms your wireless internet adapter should need replacing
- The wireless signal has trouble connecting over and over again
- Your WiFi on your laptop is unable to connect to the internet
