Sony VPCZ11DGX Wifi
You are better off buying a new 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 to communicate with your router and modem. Buying a USB wireless adapter is quick and painless because the only thing you have to know is the current operating system on your Sony laptop. Most USB wireless 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 handle everything from there.
What happens when my onboard WiFi has gone bad?
- Your wireless internet connection disconnects itself every day
- The wireless adapter on your laptop will not connect to your router anymore
- The WiFi adapter driver gives errors when installing
