If your computer's operating system doesn't install the driver of the TL-WN725N automatically after plug-in, you just need to install the driver from the bundled CD or from TP-LINK's website. After the driver is installed, you can use the built-in wireless utility in your operating system to connect to a wireless network. If you want to use advanced features of the adapter such as Soft AP, you can install the TP-LINK utility to access those functions.With its miniature size and sleek design, you can connect the nano adapter to the USB port of your computer and leave it there, similar to how you use a wireless mouse. There's no need to worry about blocking adjacent USB ports or that the adapter may fall out when moving the connected computer.
