Sony PCG-GRZ630 Wifi
The WiFi in your laptop, if so equipped, uses a piece of hardware in order to talk to your router and modem. Finding a WiFi adapter is easy because all you need to know is the current operating system on your Sony laptop. It will be easier to buy a new USB adapter and install it, than to replace any built-in adapter your laptop may have. Most USB wireless adapters are plug-n-play, which means you simply plug it into a USB port and the OS will install the drivers on its own.
Key clues of a bad wireless card
- The laptop wireless driver gives errors when installing
- The wireless signal goes in and out every day
- Your WiFi in your Sony laptop is unable to find a signal from your router
