Yesterday, we shared a tip to make use of an external USB WiFi adapter on Apple Mac computer's for better wireless experience. Luckily, the experiment Killed Two Birds with One Stone as it made the 40Mhz wide WiFi width usable in 2.4Ghz spectrum which is not made available with the built-in WiFi card. As evident from the screengrab posted below, the external USB card also makes use of full 300Mbps bandwidth resulting in faster file transfers over wireless link.
