Lenovo ThinkPad L421 Wifi
Most USB wireless adapters are simply plug and play, in that you just plug it in the USB port and the OS will handle everything from there. Buying a wireless adapter is quite easy because the only thing you have to know is the current operating system on your Lenovo ThinkPad L421. The WiFi in your laptop, if so equipped, 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 to replace any built-in adapter your laptop may have.

- The WiFi adapter on your laptop is unable to connect to the internet
- Your WiFi signal drops for no reason during the day
