Lenovo M4400S Wifi
Searching for a new adapter is simple because the only thing you have to know is what OS you are running on your Lenovo laptop. Most new Wifi adapters are plug-n-play, in that you just plug it in the USB port and the system will install the drivers automatically. The WiFi in your laptop, if so equipped, uses an adapter in order to talk to your home network. It will be easier to buy a new USB adapter and just plug it in, than to replace any built-in adapter your laptop may have.

- The laptop wireless driver suddenly shows as uninstalled
