Sony VPCCB490X Wifi
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. The WiFi in your laptop, if so equipped, uses a piece of hardware to communicate with your home router. Finding a WiFi adapter is easy because the only thing you have to know is the current operating system on your Sony laptop. Most new Wifi adapters are plug-n-play, in that you just plug it in the USB port and the system will install the drivers automatically.
What warnings should I watch out for to know if my WiFi adapter is not working properly?
- The WiFi adapter driver gives errors when installing
- Your wireless internet connection goes in and out every day
- The wireless adapter in your Sony laptop does not connect at all
