You are better off buying a new wireless USB adapter and just plug it in, than it is to replace any type of OEM adapter you might have. A lot of newer wireless adapters are simply plug and play, which just means that you only need to put the adapter into an available USB port and the system will install the drivers automatically. Searching for a new adapter is simple due to the fact that all you need to know beforehand is what OS you are running on your laptop. The WiFi in your laptop, if so equipped, makes use of a wireless adapter in order to connect to your router and modem.
