Either the 2.4GHz or 5GHz frequency band can be selected with top speeds at 300Mbps and 867Mbps respectively. Surf the internet and check emails on the longer-range 2.4GHz band, or use the high-speed 5GHz band for online gaming and YouTube or Netflix HD streaming.
11ac Wave 2 Compliant MU-MIMO
The latest 11ac Wave 2 MU-MIMO (Multiple User - Multiple Input Multiple Output) technology runs four streams and serve multiple devices simultaneously, for the fastest speeds and uninterrupted Wi-Fi connectivity to all devices.
MU-MIMO for Non-Stop Streaming
Instantly upgrades your older laptop or PC to the latest 11ac Wave 2 speeds with MU-MIMO functionality. Everyone in the room can enjoy smooth surfing, streaming and gaming at the same time when paired with a MU-MIMO router.
Beamforming Wi-Fi
Beamforming enables your Wi-Fi signal to be targeted at your adapter for a stronger, more reliable and efficient Wi-Fi connection when it paired with any beamforming router. Meanwhile, beamforming generates directional-targeted Wi-Fi signals, instead of standard Wi-Fi which radiates outwards. This means better audio quality and HD video streaming as you explore your digital wonderland.
Small, Travel-Size For Laptops
Featuring a nano, lightweight design that can be plugged into any type of laptop for more mobility and convenience. It's so tiny that it feels like nothing to carry around, and can always be with your laptop.

Rating: 5/5 Fast response, such a great item! July 4, 2018 I was looking all over for a simple, and cheap AC adapter. I could not have choosen a better product! Downloaded software, pluggged in, and zoom! This thing took off on my AC router. Easy use, just turn off WiFi card, and turned on this adapter, and it is fast. Has an icon to turn on adapter which is so easy to identify and use. Great addition to my Macboom pro.

Rating: 3/5 Be careful and read the directions before use. November 26, 2017 I bought two. The instructions for use are not clear and the setup is a bit of a fiddle. Once correctly configured and installed on my MacBook Pro, the device works as advertised. Requires the user to download and install the correct software. After turning off your internal wifi, one can use the icon on the menu bar to control the device. Software does not have the usual fit and finish one expects in the Apple world. So, it works as advertised. But the device is quite small and would be easy to lose or misplace.

If my laptop or desktop had no other wifi this would be a useful device. I find the inconvenience of using it outweighs the speed advantage. It is not in use currently.

Response from OWC, Call Center January 17, 2018 Hello! Thank you very much for your feedback and concerns with the Edimax AC1200 USB Adapter. I'm sorry to hear that your expectations may not have been met with the product. I would suggest reaching out to Edimax to see if they have any updated software available that may work a bit better for you.

Rating: 5/5 Smooth wifi connection all around! July 29, 2017 Brought this Edimax AC1200 Dual-Band MU-MIMO USB Adapter for my daughter's Macbook Pro 2012 Unibody which is limited to wireless 802.11b/g/n standards. Thus, she need to stay in our hall to get that smooth wifi connection. Hwvr, with this great product, she can now stay in her room at the other corner of our house to do all her studies & etc in comfort with air condition during our hotter months of the year in Singapore. Easy installation with the down loading of the driver form the Edimax home support page. Strongly recommended!

Rating: 4/5 Makes a difference April 7, 2017 Had a little difficulty installing this adapter - at first it would not find my network, even though it was finding my next-door neighbours' networks! After googling the problem, and with help from OWC support, I worked out that I received the US version of the adapter and that the channel I was using for my network (I am in the UK) was not compatible with the adapter. I changed channel and hey presto the adapter worked! It makes a difference to my mid 2012 MBP so I am happy.
