Lenovo ThinkPad G40 Wifi
Buying a wireless adapter is quite easy due to the fact that all you need to know beforehand is what OS you are running on your laptop. Most new Wifi adapters are plug-n-play, which just means that you only need to put the adapter into an available USB port and the OS will install the drivers on its own. WiFi, or wireless internet, uses an adapter to communicate with your router. You are better off buying a new USB adapter and just plug it in, than it is to replace any type of OEM adapter you might have.
Important signs your wireless internet adapter is dead
- The laptop wireless driver cannot be installed
- Your WiFi in your Lenovo laptop cannot see the SSID coming from your router
- The WiFi goes out randomly during the day
