Lenovo ThinkPad T420SI Wifi

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 operating system will take care of the rest. Finding a WiFi adapter is easy because the only thing you have to know is the operating system that is installed on your laptop. WiFi, or wireless internet, uses a piece of hardware in order to talk to your router. It is cheaper and easier to purchase a common WiFi USB adapter and install it, than it is to replace any type of OEM adapter you might have.

What are the indications that my wireless internet adapter is in need of a replacement?

The WiFi adapter in your Lenovo laptop is unable to find a signal from your router
Your wireless internet connection goes in and out over and over again
The WiFi adapter driver gives errors when installing
