It is much simpler to buy a new USB adapter and install it, than it is to replace any type of OEM adapter you might have. WiFi, or wireless internet, makes use of a wireless adapter in order to talk to your home network. A lot of newer wireless adapters are plug-n-play, which means you simply plug it into a USB port and the operating system will take care of the rest. Buying a wireless adapter is quite easy because the only thing you have to know is what OS you are running on your laptop.
What warnings should I watch out for to know if my onboard WiFi has gone bad?
- Your WiFi signal disconnects itself over and over again
- The wireless adapter on your laptop cannot see the SSID coming from your router
- The WiFi adapter driver shows it as not installed
