Lenovo B40-45 Wifi
Finding a WiFi adapter is easy due to the fact that all you need to know beforehand is the current operating system on your Lenovo laptop. Most new Wifi adapters are simply plug and play, in that you just plug it in the USB port and the OS will handle everything from there. It will be easier to buy a new wireless USB adapter and install it, than to replace any built-in adapter your laptop may have. WiFi, or wireless internet, makes use of a wireless adapter in order to talk to your home router.
