EDiMAXEW-7822ULC - AC1200 Dual-Band MU-MIMO USB Adapter

Okay, so this is a real small WiFi dongle that still manages 867Mbps on the 5MHz band and a decent 300Mbps on the 2.4MHz band. So far it's worked flawlessly! There's not much more that I can add to this, it works, and it works well!*Update! Well, I can update my review a little bit. I've been connecting with this to an Asus RT-AC68U, and my results on the 2.4MHz band are..... Surprising, as it can establish a stable 400Mbps connection, and has on occasion peaked above this - that's actually higher than the specs suggest is possible!

I bought the Edimax AC1200 WiFi Adapter because the internal wi-fi card in my mid-2009 MacBook Pro had stopped working. Apparently its a known problem on this generation of MacBook but fixing it is fairly difficult or very expensive. The card itself is built into the hinge of the laptop and a fair amount of dismantling is required to get at it, hence the cost.The mini-CD included with the AC1200 cannot be used on a slot loading Mac but the up-to-date driver was available on the Edimax site so I downloaded it. The instructions said to delete the existing wi-fi profile. This can be found and disabled in System Preference/Network. I then installed the Edimax Driver, plugged the mini-dongle into a USB port, rebooted and a tiny icon appeared on my top bar. Click on this icon and a fairly familiar sub-menu appears showing all the wi-fi signals within range. It works!I don't know how long it will last and I don't know if the technical specs are better or worse than the Mac's original AirPort card but I DO know that it was a quick and cheap way to keep my MBPro alive. NB: The mid-2009 MacBook Pro can only support up to Mac OS X 10.11.6 so there were no issues with OS compatibility for me.

Wireless broke on mac after 6 years of use. Decided wireless dongle would be the best option. Tried another product before this and had problems connecting, and it was also too large. This was a little more expensive but reviews online were good. But overall the price was decent compared to a repair. Very nice size, barely noticeable next to my laptop and my laptop still fits its case so that it doesn't have to be removed. 3 issues: signal strength is weaker at range than my original wireless, however moving closer to the router and this is no longer a problem. Occasionally, it does not connect by itself, however clicking on the wifi network manually has seemed to solve this almost instantly every time. It also runs quite hot, which might be expected due its size, however I've not had any problems because of this so far. Insurance was bought just in case. Overall I am very happy with this purchase and this solution and it has saved my beloved macbook pro.

I purchased this for a Hackintosh and it works really well with it. I had tried others but the drivers never worked properly with them.

Fast, reliable, small, unintrusive, always connects, never drops out. Perfect. Revived my macbook wifi.

Heads up. If you have Mac OSX Catalina Edimax do not have a driver that will runs this adapter . I bought one which arrived today, and will be returning it. Companies that do not keep drivers up to date with new system software updates do not deserve the custom.UPDATE: I have managed to find a work around for those trying to use this with MAC OSX Catalina. Go to this link and follow his instructions carefully. Also, watch the video he has posted for catalina. Then Download his Release V7 ➤ Wireless USB Adapter.pkg This all works OK but hopefully Edimax will post a proper driver at some point.

There are two types of 5GHz bands, two channel groups.- One group is, for example, channels 44-46-48 ["Band 1"]- The other group is, for example, 147-163 ["Band 4"]This WiFi adapter can only receive the first of the 5GHz bands. So if that is a limitation you'll be forced, like me, to fall back on the 2.4GHz signal instead. So much for the term "dual-band".I have confirmed this with EdiMax support.Even if, like me, you checked the EdiMax specs for this model, you are expected to have realised thatFrequency• 2.4000 - 2.4835GHz• 5.150 - 5.825GHz*FCC: Band 1: 5.150~5.250(GHz)Band 4: 5.745~5.850(GHz)CE: Band 1: 5.150~5.250(GHz)means"FCC" - the version they sell in the USA [it is not just saying that these FCC specs are met, they are saying it is a different product]"CE" - the version they sell in Europe [it is not just saying that these CE specs are met, they are saying it is a different product]So I now have an EdiMax router [BR-6478AC V2] and this EdiMax WiFi adapter that cannot receive the 5GHz WiFi signal that is my internet connection and both limitations hid behind this reference to FCC & CE standards about which we were supposed to be clairvoyant.I am never going to buy another EdiMax product.

Good product
