Buying a USB wireless adapter is quick and painless because the only thing you have to know is the current operating system on your laptop. 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 a piece of hardware in order to connect to your router and modem.
Clues to watch for to know the wireless card is in dire need of a replacement
- The WiFi adapter on your laptop is unable to find a signal from your router
- The WiFi adapter driver gives errors when installing
- Your wireless internet connection goes out randomly every day
