Sony PCG-K47 Wifi
Most new Wifi adapters are plug-n-play, which means you simply plug it into a USB port and the system will install the drivers automatically. WiFi, or wireless internet, uses a piece of hardware in order to connect to your home router. Buying a wireless adapter is quite easy due to the fact that all you need to know beforehand is the operating system that is installed on your Sony laptop. It is cheaper and easier to purchase a new wireless USB adapter and just plug it in, than it is to replace any type of OEM adapter you might have.
Major indications of a declining onboard WiFi
- The WiFi adapter driver suddenly shows as uninstalled
- The wireless signal drops for no reason every day
- The wireless adapter in your Sony laptop cannot see the SSID coming from your router
