Lenovo ThinkPad T43 Wifi
It is cheaper and easier to purchase 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 operating system will take care of the rest. Buying a wireless adapter is quite easy because all you need to know is the operating system that is installed on your laptop. The WiFi in your laptop, if so equipped, makes use of a wireless adapter to communicate with your router and modem.
