It will be easier to buy a new USB adapter and just plug it in, than it is to replace any type of OEM adapter you might have. Most USB wireless adapters are plug-n-play, in that you just plug it in the USB port and the OS will install the drivers on its own. Buying a USB wireless adapter is quick and painless because all you need to know is what OS you are running on your laptop. The WiFi in your laptop, if so equipped, uses an adapter in order to connect to your home router.
Clues to watch for to know your wireless internet adapter will soon need to be replaced
- Your wireless internet connection has trouble connecting over and over again
- The laptop wireless driver suddenly shows as uninstalled
- Your WiFi on your laptop is unable to find a signal from your router
