Amped Wireless ACA1 High Power 500mW Dual Band AC Wi-Fi USB Adapter
Amped Wireless ACA1 High Power 500mW Dual Band AC Wi-Fi USB Adapter Now that Apple has added 802.11ac to its latest MacBook Airs and AirPort Extremes, it’s only a matter of time before the next-generation Wi-Fi standard makes it to the rest of the Mac lineup. Owners of current-generation machines have an option, too: Amped Wireless has just introduced the ACA1 High Power 500mW Dual Band AC Wi-Fi USB Adapter ($90). Large thanks to a couple of brawny antennas, ACA1 adds 802.11ac compatibility to machines without it, and boosts transmission distance by up to three times.ACA1 connects to your Mac over USB 3.0, and can either clip onto the screen, or rest on a flat surface next to it. After you’ve installed a driver, it’s ready to go, allowing you to move further away from an 802.11ac router without losing signal—though with the standard 802.11ac caveat that transmission speeds drop as you move further away from your router. It’s backwards-compatible with earlier 802.11 standards, as well.
