1 out of 5 eggsHorrible speed. Not worth your money

Pros: - It is small
- It did connect me to the internet

Cons: - I only got 2.5Mbps down, while my laptop sitting just beside the desktop could get 30+Mbps down.

Other Thoughts: Don't waste your money. Buy a different product.
I have my router in the basement, and the desktop just above the router (total distance under 2 meters) separated by just a wooden floor. All my other devices (2 cellphones, 2 laptops) are getting good service all around the house. I just built a new desktop with the Asrock Z170M Extreme4 motherboard, which doesn't have on board wi-fi, so I bought the dongle rather than drilling the floor. Latest drivers downloaded from Edimax's website and still horrible speeds. Not worth your money. I'm gonna try returning the product if I can.

Manufacturer Response:

Hi Vladamir,

Thank you for your feedback.

The actual download speed will vary depending on your environment. If you have the adapter plugged in the back USB port, I would recommend using it on the front USB port. Since this is a Nano USB adapter the antenna will differ greatly from a laptops antenna. You can try to change the channel on your router to see if this helps, since some channels can be congested with other Wi-Fi networks.

If you have any questions, please feel free to contact us at 1(800)652-6776 or email us at "support@edimax.us"



Best Regards,

3 out of 5 eggsYou get what you pay for

Pros: - Great value
- No major catastrophic problems

Cons: - A little slow; did at times throttle my already slow connection speed
- Sometimes requires a reset to be able to connect to the internet (but not the network, oddly enough)

Manufacturer Response:

Hi Lucas,


Thank you for your feedback.

Since some channels on the 2.4GHz wireless settings maybe congested, you can try choosing a different channel between 1-11 on your router. In addition, you can force it to run at 40MHz for faster speeds.

If you have any questions, please feel free to contact us at 1(800)652-6776.

4 out of 5 eggsWorks very well on Mac and PC

Pros: Plug and play with Windows 10. Works very well with Mac OS 10.11.4 (El Capitan). Small.

Cons: Over 10 meters the signal become weak.

Other Thoughts: I recommend this product for Macbook Pro, if your Airport card is broken.

5 out of 5 eggsGreat upgrade for an old laptop.

Pros: Very easy to set up in Windows 7 and has been working well for over eight months. Easy replacement for a failed 802.11G unit in a 2007 laptop.

Cons: None

Other Thoughts: This has a blue LED built in which blinks with wireless network activity.

4 out of 5 eggsWorks well on my Raspberry PI 2 b

Pros: Good solid connection using LINUX MATE

Cons: I got this because it was advertised as compatible with the Raspberry PI. While this is true there is no documentation on how to install drivers etc. I was able to get it to work using the native LINUX MATE configuration.

Only 4 eggs for lack of documentation.

Other Thoughts: This appears to be a good low price solution to WiFi for the RP 2. (I now see the RP 3 is out with WiFi built in.) I would buy this again and recommend it to others.

2 out of 5 eggsworks to a degree

Pros: got me a wireless internet connection

Cons: says it supports up to 150 Mbps i was only able to get on average .70 Mbps with a 10 Mbps internet connection from my ISP and that's only with one wall between me and the router with me 20 ft from it. It also would stop working from time to time.

Other Thoughts: no man should be forced to watch youtube in 360p

Manufacturer Response:

Hi Thomas,


You may want to try a different channel on your router between 1-11. You may also want to try setting the channel frequency to be 40 MHz. In addition, maximum performance, actual data rates, and coverage will vary depending on network conditions and environmental factors.

If you have any questions or concerns, please feel free to contact us at 1(800)652-6776.

3 out of 5 eggssmall adapter small signal

Pros: It is a very small adapter that can fit almost anywhere without making an infringement on space. The install was very easy and the edimax software interface works well. It also functions with my Ubuntu setup.

Cons: The signal reception for this adapter is quite low. If you are in the same room as your wireless router or not too far away it is great, but if you go through too many walls, across too large a distance, etc... the signal drops pretty low. I am on a campus with an extensive wireless net right now and it only pulls in a signal strength of about 46 - 50% which is passable and but not good. My internal 802.11b/g wireless adapter on my laptop has better reception.

Other Thoughts: For home use in the same room this is great, but if you want to take it mobile or across the house get something with better reception.

Manufacturer Response:

Dear Customer,

Thank you for supporting Edimax.

Since the EW-7811Un is a Nano USB adapter, the antenna's coverage will decrease if there is a lot of interference.

If you still have any questions or concerns, please contact our customer service at 1(800) 652-6776 or write an email to "support@edimax.us ".

5 out of 5 eggsEasy to install

Pros: I love these things! You need no extra drivers in Linux, including Raspbian. I bought three so I could have one to carry around just in case of emergencies and one extra.

Cons: Not sure about range. I haven't really tested it, but I suspect it won't go the range of a PCI card. Of course, that isn't why I bought them.

Other Thoughts: Well, they are small and easy to lose. I had this same type before I moved, and who knows where it went?
