Acer Aspire 7120 Wifi
It will be easier to buy a new wireless USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. Most new Wifi adapters are simply plug and play, which means you simply plug it into a USB port and the operating system will take care of the rest. Buying a USB wireless adapter is quick and painless because all you need to know is the current operating system on your laptop. The WiFi in your laptop, if so equipped, uses an adapter in order to connect to your router and modem.
