Acer Aspire 9120 Wifi
Most USB wireless adapters are plug-n-play, which just means that you only need to put the adapter into an available USB port and the OS will handle everything from there. You are better off buying a new wireless USB adapter and install it, than to replace any built-in adapter your laptop may have. The WiFi in your laptop, if so equipped, uses an adapter in order to connect to your home router. Buying a wireless adapter is quite easy because the only thing you have to know is the operating system that is installed on your laptop.
