EdimaxWi-Fi 5 802.11ac AC1200, Dual-Band 2.4/5GHz Adapter for PC, Wireless AC USB 3.0 Adapter Dongle w/ Foldaway Antenna, Up to 867Mbps Fast Transfer, Win11 Plug-n-Play, Mac OS, Linux, EW-7822UAC

With my laptop's onboard network card, I was getting between 20Mbps and 30Mbps. Spectrum says I can get "Up To" 300Mbps.My router is an "ac1750" Dual Band. It says 450Mbps on 2.4GHz and 1300Mbps on the 5GHz side.What I Actually Get: (With this adapter)On the 2.4GHz side, I get 50Mbps. On the 5GHz side, I get 200MbpsRunning across an Ethernet cable, I get 265Mbps.So, I am very happy with my purchase.I will probably buy another and ditch the cable all together. Although; That extra 50 to 60 Mbps I get running over the cable chops minutes off my download times. Decisions, Decisions; Yeah, I get another.NOTE: These are actual download speeds as seen from my computer's "Task Manager" Performance page. If you use an app like "OOKLA" or any other speed test done online, it will show you a speed about 25 to 50 Mbps faster than you will actually be getting. Just saying.

Update; With the new driver for MAC, installation is easy and quick. The most important thing is to toss the CD and go to the correct website, ediman.us for drivers. Once the driver is installed and your MAC restarts, the edimax icon appears in the menu bar to the right of the airport icon. Just like the airport icon, click on the edimax icon, select your network from the dropdown and log in. On many MB Pros the airport card disappears. I'm using these to resolve the issue and recommending them to folks who ask.The directions are not very clear and the drivers on the CD provided are not up to date and are not labeled for each MAC OS. There is some help online and also tech support by email. After submitting my questions by email, I received a call within hours. The most important thing is to use the edimax.us site, not thee edimax.com sight!!! The drivers on the US site are labeled for each OS. 10.10 is the latest OS for which they have a driver, but 10.11 is promised soon. After the application is installed, open the wireless network utility, click on the "available networks" tab, select your network and log in. I downgraded this MacBook pro to 10.11 and it works. I tried on other MACs in earlier OSs and couldn't make it work. It worked smoothly after do a clean install of OS 10. My MB Pro is usable again.These are the instructions Edimax support sent me.Please try downloading the driver for 10.8 from our website at, "[...]". We have separated each OS driver for MAC.1. Once you download the driver, there will be 2 packages inside.2. Please run the "uninstaller package" first, then run the "installer package".3. After you install the driver, please refer to the Edimax Wireless utility guide, to enable your Wi-Fi.The latest driver is available to download with the link below. Once you have the driver downloaded, there will be a file inside that you can run to uninstall the driver.[...]Once you have downloaded the latest driver file, Edimax.dmg, from our web site, please open that Edimax.dmg file. There are two packages inside, USBWireless-install.pkg and USBWireless-Uninstall.pkg.Run the USBWireless-Uninstall.pkg package first.Go through the installation process of it and it will need you restart your computer.After restart, check your \Applications folder.You should not see Edimax Wireless Utility nor any other wireless utility existed in \Applications folder.If you still see a Wireless Utility there, please move it to trash bin.Once you verify there is no Edimax Wireless Utility in \Applications folder, you can go ahead to run the USBWireless-install.pkg file. The installation is quite straight forward.

This is my third AC1200 network adapter. The first was totally unreliable and I returned it. The second had periods of trouble free operation but eventually devolved to dropping the connection and sometimes spontaneously disabling itself at least once a day. By then it was beyond the Amazon return period. I had been using an under $15 AC 450 adapter from the same manufacturer as AC 1200 #1. It worked perfectly. I bought this one as a final try. I decided that if it failed I'd stick with the AC 450. So far so good. It's worked for a couple of weeks. Oddly enough it has the same chipset as AC 1200 #2. The Realtek utility that didn't work at all with #2 works with this one, which didn't include a utility in its software.Beats me what's going on. AFAIK there are 2 and only 2 kinds of chipsets available for wireless AC 1200 USB adapters. I'm assuming there are minor differences in the implementation that have large effects. A network adapter is one of those things that should never be noticed after you install it. It should just deliver the electrons. That appears to be what this one does. I'm hoping it continues to work. The computer I'm using it with is in a room that's too hard to run a data cable to. I don't have much choice but to use wireless. It's faster than 10/100 ethernet so I will be happy as long as it's reliable..

I have a couple of Edimax EW-7811UTC AC600 Dual-Band USB Adapters from the same manufacturer also purchased at Amazon for half the price, and they both perform much more reliably than this AC1200 device and are just as fast in terms of internet download speeds on my system. I pay for a 100 Mbs connection and routinely get 85 with both the AC600 unit and the AC 1200 unit BUT the AC1200 unit varies quite a bit and drops connections. Odd because they seem to basically use the same driver. That's my experience. If you're just using it for the internet, stick with the cheaper and much more compact EW-7811UTC. It is very possible that if you are connecting wirelessly to a home or business network rather than the internet, the AC1200 unit might be much quicker. As usual, your mileage may vary, but that's my experience. Both of these Edimax adapters can be made to function under Linux as well as Windows, but loading the Linux drivers require a small amount of command line coding.
