The Edimax EW-7822ULC Wi-Fi adapter operates on 2.4GHz and 5GHz frequency, and delivers combined speed of up to 1200Mbps (300Mbps on 2.4GHz + 867Mbps on 5GHz).

The EW-7822ULC runs ultra-speed 802.11ac Wi-Fi that’s almost three times faster than 802.11n. Upgrade your laptop or PC to sport 802.11ac Wi-Fi so you can enjoy online video streaming and multiple data transfers at the fastest speeds.

General information

Beamforming Wi-Fi

The EW-7822ULC’s 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.

Overall Review: I would give it no eggs but it won't let me.

Pretty good 3/22/2018 8:08:48 PM

Pros: Faster than 802.11n. Dual band. Fairly small. Plug and play with Windows 10 1709. No issues with heat. No issues with reception on either band.

Cons: Slightly larger than Edimax's previous nano wifi adapter (EW-7811). As other people have mentioned, even though its an AC1200 adapter, it's built on a USB 2.0 platform, which has a maximum throughput of 480mbps. So don't get this if you're expecting it to operate at the full speed your router may be capable of.

Overall Review: I did some testing with the program LANtest to see what kind of throughput this thing gets.
Compared it to the built in wifi adapter and the previous Edimax nano wifi adapter.

Testing was done from a Lenovo Flex2 using the USB 3.0 port (4th gen i5). All tests were done connected to a Tenda AC1800 router. Device on the other end of testing was a DS218+ NAS on a wired gigabit port.

Pros: -Excellent speeds
-Small Form Factor so you can leave it in your machine

Cons: -Gets extremely hot
-Loses connection after 30 minutes due to over heating even when just web surfing not downloading
- actually throughput is 25% of total bandwidth even in an area of low interference

Super easy Wifi. Windows 10 just runs with it. 4/30/2017 9:45:34 AM

Pros: Tiny, low power consumption, fast, effective. It's the whole package !

Cons: Don't know what the range potential is, that might be a drawback, but works fine in all the situations I come across.

Overall Review: Use this with USB 3.0 or 3.1. USB 2.0 will limit your speeds to a fraction of what it's capable of.

If you have a machine that needs wifi, this is a great, non-intrusive, easy solution.

Don't have a heat problem like some others. If one of these gets anything more than slightly warm, there's an issue for replacement.

Don't waste your money 4/13/2017 4:41:55 PM

Pros: It did technically connect to the internet, but....

Cons: I got a whopping 1.2 Mbps download speed using Google's speed test. I bought a different adapter and it jumped up to ~35Mbps.

Overall Review: I'll be returning this product.

Dear customer,

We appreciate your feedback about our nano AC1200 wireless adapter.

What is the operating system of your computer? Maybe we have a newer driver available for your opeating system.
Do you connect the nano ac1200 wireless adapter to 2.4Ghz WiFi or 5Ghz WiFi? Usually 5Ghz WiFi is faster than 2.4Ghz WiFi, however, 2.4Ghz WiFi can have longer range than 5Ghz WiFi.
How far is it from your computer to your WiFi router?

We need more information to assist you.

For any further assistance, please contact our technical support at 1(800)652-6776 or write an email to "support@edimax.us" during our office hour M-F 9am to 5pm. Our tech support team will assist you with the issue.

Didn't notice these were USB 2.0 until too late 4/11/2017 6:07:54 PM

Pros: Might be faster than what you have if you have an old computer / wifi adapter.

Cons: USB 2.0 interface is definitely a bottleneck on these. I should've just stuck with my built-in Wi-Fi adapter, these were no faster because of the 2.0 USB spec that I missed when ordering

Good product. Works great! 4/10/2017 11:03:39 AM

Pros: Small. Easy to set up. Connects every time.

Cons: None

Overall Review: Connected to my router flawlessly and had speeds that I am happy with especially when you consider it is USB 2.0. I did not measure the speed; however, it is comparable to my ASUS U8B-N13 external adapters for performance. Not gaming. etc. with this, just surfing, updates, downloads, etc. so I am very pleased because of it's price, performance and concealment; no need to worry about breaking it away from the USB port. Never had any issues with heat even after downloading a 300+MB file. I used this on the back of a Windows 10 computer in my basement and the gigabit router was on the floor above me and a good 45 feet away at that! I would definitely recommend this a for anyone that casually uses the internet.
