Sony PCG-R505JS Wifi
It is cheaper and easier to purchase a common WiFi USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. Most USB wireless adapters are simply plug and play, which means you simply plug it into a USB port and the OS will install the drivers on its own. The WiFi in your laptop, if so equipped, uses an adapter in order to talk to your home router. Searching for a new adapter is simple because the only thing you have to know is the operating system that is installed on your laptop.
Key clues of an unhealthy WiFi adapter
- Your wireless internet connection drops for no reason during the day
- The laptop wireless driver gives errors when installing
- The wireless adapter on your laptop is unable to connect to the internet
