Product Description

The Edimax EW-7822UAC USB 3.0 adapter is the next generation of Wi-Fi adapter, compatible with the draft 802.11ac standard and delivering speeds of up to 867Mbps at 5GHz - almost three times as fast as 802.11n. The EW-7822AC is the first adapter of its kind to offer 802.11ac speeds together with USB 3.0 connectivity. Upgrade PC's and notebooks to super high speed 802.11ac Wi-Fi and enjoy streaming video and data at speeds of up to 867Mbps.

USB 3.0 is up to 10 times faster than USB 2.0 and specifies a maximum transmission speed of up to 5Gbps. Providing quicker data transmission times, and backwards compatibility with USB 2.0 (which specifies a maximum speed of 480Mbps), USB 3.0 is the new standard in connectivity - enabling devices to achieve the superfast speeds which 802.11ac can provide.

Dual-band Connectivity
Enjoy better performance and greater flexibility for your Wi-Fi devices, using dual-band connectivity. The EW-7822UAC provides concurrent connectivity for the 2.4GHz band and 5GHz band at speeds of 300Mbps and 867Mbps respectively.

Download and Stream Anywhere
Use the EW-7822UAC to download and stream media from YouTube, Netflix or other services without waiting for buffering, or stream media across your network from a NAS (network-attached storage) at lightning speeds. Streaming HD movies or downloading is faster and more reliable than ever with 802.11ac Wi-Fi.

Adjustable Foldaway Antenna
The EW-7822UAC's sleek design features an adjustable foldaway antenna, allowing users to adjust the antenna's angle for optimum Wi-Fi performance and fold back the antenna to minimize size when it's not in use.

Edimax EW-7822UAC Wireless AC1200 Dual Band USB 3.0 Adapter Review

This adapter is *incredibly* fast for WiFi. I am able to consistently get over 200mbps in a real-world environment (through a wall, adapter located ~18 ft from the router). Needless to say, I am very happy. Note that I am using USB 2.0, which has a maximum theoretical transfer rate of 280mbps - it is possible that this card would be even faster if connected to a USB 3.0 port.

To those of you who were expecting to get 867mbps - Edimax publishes the aggregate full duplex bandwidth number. It can be a little confusing at first, because it's different than what we're used to with wire networking. In wired networking, the 1Gbps advertised speed represents the speed that the adapter is able to achieve in *each* direction. In wireless networking, the industry standard is to advertise the sum of the speeds that can be achieved in *both* directions ... so if wired cards were spec'd like wireless cards, they would be referred to as '2Gbps' (and conversely, if this were a wired card, it would be advertised as 433 mbps). Since this is the industry standard in wireless networking, I think that Edimax's specification of '866Mbps' is fair. That being said, don't expect to get 433mbps unless you live in an interference-free area (basically if you live way, way out in the country) and have a line-of-sight between the router and adapter. Even if you can only achieve 200-300mbps, you're still getting the fastest performance that has ever been available in wifi (as of 6/2013) for a bargain price ($39.99 at this writing).

Another thing to be aware of is that due to the physical properties of 5Ghz RF, it will *never* pass through walls and other structures as well as 2.4Ghz. In general, with RF communications the rule is that as frequency increases, more of the signal will be absorbed by structures. Since this is a dual-band adapter, if you'd like to use it on a different floor than the router is located on, or through some troublesome walls, I suggest using it with a 2.4Ghz network. You'll pay a price in maximum performance, but you'll
be rewarded with a more stable connection.
