Sony PCG-R505DC Wifi
Finding a WiFi adapter is easy because the only thing you have to know is the operating system that is installed on your Sony laptop. A lot of newer wireless adapters are plug-n-play, which just means that you only need to put the adapter into an available USB port and the operating system will take care of the rest. It will be easier to buy a common WiFi USB adapter and install it, than to replace any built-in adapter your laptop may have. The WiFi in your laptop, if so equipped, makes use of a wireless adapter in order to talk to your wireless router or modem.
What are the signs that the WiFi adapter is about to fail?
- Your wireless internet connection goes in and out every day
- The WiFi adapter driver suddenly shows as uninstalled
- The wireless adapter on your laptop will not connect to your router anymore
