BenchmarkReviews.com: Built on the same design slate as the black diamond series, comes the ASUS USB-N53 Dual Band Wireless-N300 USB Adapter. The USB-N53 has two built in antennae and can operate on 2.4GHz and 5GHz signals at up to 300Mb/s. On the box ASUS claim that the USB-N53 has a "Superior antenna design for extensive wireless coverage more than 150%" and this does show through in our tests, our testing threw out some good numbers but nowhere near 300Mb/s which is understandable to a certain extent. The ASUS USB-N53 comes bundled with an adjustable USB cable that allows you to position the adapter for a better wireless connection. If you are eager to find out more jump on in and see if the USB-N53 is right for you.
