Buying a USB wireless adapter is quick and painless because all you need to know is the operating system that is installed on your laptop. 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. Most USB wireless adapters are simply plug and play, which means you simply plug it into a USB port and the OS will handle everything from there. The WiFi in your laptop, if so equipped, uses a piece of hardware to communicate with your home network.
Major clues of a defective wireless card
- Your WiFi on your laptop is unable to connect to the internet
- The WiFi has trouble connecting over and over again
- The wireless adapter driver gives errors when installing
