Works with Linux - mostly...

This is one great wireless device! Works out of the box with Ubuntu 18.04 and works with Debian 9.4 / 9.5 as long as you download the non-free firmware iso on the Debian site. Additional info for Debian and all ran as root (or sudo): Once the OS is installed, you will need to run the following command: ln -s /dev/null /etc/systemd/network/99-default.link This will disable the auto rename of the interface that invariably "confuses" Debian and renders the nic useless. Once this is symlinked, simply reboot and bingo. Alternatively, you can edit /etc/default/grub Look for the line: GRUB_CMDLINE_LINUX="" and change it to: GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0" Then run: update-grub then reboot This does the same as the symlink and probably a lot cleaner UPDATED 7/22/2018: After running this for a few days. I am seeing much of what some of the others have been saying. I am seeing serious lags with this device. For example, accessing a share on my locale network will sometimes take 1 to 2 minutes before there is network activity and eventually produces a simple listing of a directory. The same goes for accessing the internet for that matter. Mind you, I have any and all sleep/hiber/power saving modes disabled. This does not happen when I remove this device and use my old Panda PAUO5. So there is something with this nic.

Windows-10 Software Updates That Work!

I recently upgraded my old Windows-7 laptop to the “free” Windows-10 promotional offered from Microsoft. Even under Windows-7 the WiFi interface had been problematic and the issued continued under Windows-10. Given the advanced age of the laptop, I didn’t want to invest a lot of money fixing the WiFi. In reviewing Amazon’s USB WiFi solutions, the Edimax EW-7811Un appeared to be likely low cost solution were it not for the large number of negative reviews which were offset by the still larger number of positive review. I decided to take a chance and ordered the Edimax EW-7811Un. When the Edimax EW-7811Un arrived, I was able to use the default Windows-10 and Mini CD-ROM to install the driver and support software; however, neither solution worked for longer than several minutes before failing. Most troubling was that the Edimax EW-7811Un “ALMOST” worked. When I read the current product reviews, as they pertain to Windows-10, I realized that my experience was not unique and there were a number of unhappy people who ordered the Edimax EW-7811Un for use with Windows-10. In reviewing several USB WiFi solutions on Amazon, I noticed that the Windows-10 upgrades were more problematic. This could be caused by (1) older and slower hardware or (2) the Windows-10 upgrade image was not quite the same as a native Windows-10 image. For several days I considered writing a scathing review while devising alternative solutions but kept returning to the fact that the software was almost on the cusp of working. Finally, I called the Edimax support number, expecting technical support Hades, only to be quickly connected with a knowledge support technician. When I described the problem, the technician indicated that the wrong software was being distributed for Windows-10 and provided guidance on where to find the correct software, which was not on the primary Edimax website. As Amazon doesn’t support the posting of URL’s, the following navigation is provided on where to find the correct software: Navagation: edimax.us | support | download drives On the “Driver & Manual Download” page, go to Section 7 and download the ZIP compressed driver EW-7811Un Win v1.0.1.4, which is the first entry in Section 7. I used a tablet to download the file EW-7811Un_Windows_driver_v1.0.1.4.zip and then transferred the file to Windows-10 using a USB interface. Un-ZIP the file, using Windows-10, and then run the program “Setup”. This not a GUI and runs under a DOS shell, so just wait until it completes. As Edimax Support recommended, reboot your Windows-10 system, and you should be good to go! A few off-the-cuff observations: (1) A built-in laptop WiFi generally has a hidden and sometimes large antenna under the case. The Edimax may not work in WiFi marginal areas of your home. There are Edimax products with large external antennas but these will not have the small form factor of the Edimax EW-7811Un. If the connection is very poor the Edumax is flagged as “Turned Off” and you may have to use Windows-10 to re-enable the WiFi. This could be a bug! (2) I noticed that the Edimax EW-7811Un sometimes appears to go to sleep. Turning Device “Power Management” OFF may correct that problem. I have now run a four hour series of serious stress tests and, with the exception of marginal areas in my home, the Edimax EW-7811Un has performed well. I am giving this product “Five Starts” because of the good performance at a very affordable price point. Yes, Edimax’s software quality control was troubling in this case, but I would give their Technical Support “Six Stars” without a second thought. Microsoft Windows-10 upgrade policy was highly innovative and has given new life to older hardware and after market upgrades such as the Edimax EW-7811Un. Edimax and Amazon have to do a better job of communicating the good news to their customers.

Works well....

Works, but as for me it doesn't pickup my 5G Ubee modem/router it only seems to see the 2G. That is fine for me and I'm not going to take off any stars for that... I didn't see it claiming 5G... For some reason my Dell Latitude E6410's built in Intel(R)Centrino(R)Advanced-N 6200 ANG wlan chip wouldn't connect easily to my home network. It always took several attempts and even a reboot to get it to connect. I decided to give this Edimax a try and it works perfectly. Connects to any network now on the first attempt. Not eight attempt + plus a reboot like before. :-( I suspect since this is a very old laptop Intel didn't bother to update the drivers and since I bought this laptop from a certified refresher whom installed a licence copy of Windows10 Home for Refurb PC's --- the laptop is running an operating system it didn't originally ship with. So that driver probably didn't work well with either Windows 10 or the newer Ubee modem/routers... Either way this fixed the problem and was a cheap fix. This Edimax is using REALtek chips and drivers... So it seems to work perfectly...

Perfect to tether cell phone to tower computer.

I needed to link my cell phone as an internet hot spot and wanted the freedom of cordless connectivity. Unfortunately my tower computer didn't have a WiFi card so I ordered this little 7811un USB dongle. Installation was effortless; just inserted the mini-cd and let it install the drivers, rebooted and plugged the Edimax in, Win7 installed the device and there we went, good to go. Phone provided the password from Settings> Mobile Hotspot and Tethering, computer liked it and the connection was running. Now I could get some work done before the ISP came this Friday for their install here on Gilligan's Island. Some users have mentioned a limited range concern, considering that there is no large antenna and it's running on 5 volts from the USB bus, but as far as my needs go, a limited range is a bonus for security, the fewer other computers that this dongle can reach, the better. Though I've had it for only a couple of days, this little WiFi unit has paid for itself already by saving a trip to town to use a library machine (and how secure are those, sitting out in plain view?) There's a little LED that blinks to show the connection status. The device does get a bit warm but not dangerously so. There is a small flange around the end of the device to help afford a grip to remove it from the USB socket. I'd say the only downside is it'd be really easy to misplace because it's so small. Altogether it was trouble free to install and an inexpensive unobtrusive answer to retrofit an older tower machine for WiFi.

Great product for the price and easy to use.

Very easy to use and works great for my older desktop computer that did not have WiFi capability. Make sure to install the driver software first and reboot the computer and then plug the adapter into your USB port. Give it a minute to search and it should show wireless networks that are available. I am using on Windows 10 Home version. Follow instructions and you should be fine with installation.

Perfect for Linux - Updated

The original review below was for the Edimax EW-7811Un 150Mbps 11n Wi-Fi USB Adapter, Nano Size. It worked so well I decided to buy the AC1200 model. That review is at the bottom. I don't know where I bought this. I thought I bought it on Amazon but I guess not. Anyway I have had it for about a year. I use it on various laptops because it is always faster than the internal Wifi and it is so tiny that I can just leave it plugged in and not worry about it getting snapped off. You may have to install the drivers on old Linux kernels. However, it ran out of the box for me on Manjaro running kernel 4.14. When I plugged it into my Linux Mint 19 (Linux kernel 4.15) the Network Manager did not see it. It did show on a lsusb so I started to look for the drivers. While getting ready to install them, it just started working. It also ran straight away on a very old, very small Acer running Peppermint 9, also with Linux Kernel 19. It connects at 150 mbs every-time on every machine and Linux. I plan to buy the dual band version of this. I am very happy with Edimax. Edimax AC1200 Wi-Fi USB Adapter Supports Web 2, MU-MIMO, Nano Size Lets You Plug it and Forget it, for Windows, Mac OS, Black/Silver (EW-7822ULC) I installed this on my Linux Mint 19.1 laptop. It sees it in lsusb right away but does not start up. I searched for the driver based on the id # in the lsusb and found the Edimax website with very clear and straight forward directions, giving each command necessary. However it was not for mine. You need to make sure that you search for the EW model number. There are several and they use different drivers and apply to specific Linux kernels. You may want to search before you buy to make sure it supports the kernel you are using. I plan test it on the latest Manjaro, I am running the 4.14 kernel there as it is the most stable for the system it is on. I will also test on LMDE Cindy. While I am a fairly experienced Linux user, anyone who is comfortable with terminal commands and knows what lsusb is, why I don't explain it here, then should have no problems. Read the install directions first, before you buy, and decide. for yourself

Great Range & Throughput

I'm personally very weary about UB WIFI adapters. My parents had one of their personal PC at home and they would call me up to help them reconfigure it occasionally. The firmware was a nightmare, the support was lacking, and for some reason the little device ran insanely hot. Overall it left me with a bitter impression for USB WIFI adapters. Fast forward to present day, I needed a USB WIFI adapter for my Raspberry Pi 2. I decided to pick up this model after doing some research and comparing reviews to other-like devices. I could not be more pleased with the results. The range is surprisingly good. The one my parents had could barely get two bars going through one floor - this little guy gets dang near 5 bars all over my 2 story house. To put in perspective: my router is in my attic on the 3rd floor, I can go to the basement and still have a strong enough signal to work. That is simply amazing. Throughput is also another surprising factor. The one my parents had you could tell was struggling. Loading something as simple as Amazon would take a century. This device is lightning fast and allows as much throughput as your ISP/Router is designed to throw out. Overall I am extremely pleased with this device. If you are looking for an adapter for your own PC or something for a Pi device like I did - buy this.

Great little Wi-Fi USB Adapter; 100% Raspberry-friendly

I have three primary reasons why I like to use this WiFi adaptor with my older Raspberry Pi boards which don’t have onboard WiFi, such as the Raspberry Pi 2 or Raspberry Pi Zero v1.3 boards: 1) This WiFi adaptor is incredibly small, not much more than the connector, and hence doesn’t tend to get in the way at all once plugged in. 2) The Raspbian OS, and other OS’s I have used have the appropriate driver support built-in, so there’s no muss, no fuss in getting this adaptor to work with Raspbian. 3) But there’s also a more subtle benefit in that if you boot into the NOOBS loader, there too that limited system will recognize this adaptor, as it would for built-in WiFi on the Raspberry Pi 3 or Raspberry Pi Zero Wireless boards with their onboard WiFi support. This means that you can boot into NOOBS Lite which requires network connectivity to download a system, and work completely wirelessly without the need for an Ethernet connection as would otherwise be the case (on the Raspberry Pi 2 board). Great adapter!

Inexpensive, Easy Install, High Quality, Very Durable, and Extremely Reliable

Some how my son managed to kill the WIFI network in his laptop computer. Rather than face an expensive repaired and being without the system for an extended period of time, I ordered one of these and in two days he was back up and running and it has never missed a lick. Sometime later, I had loaded one of my older laptops to my ex-wife, and again somehow the internal WIFI interface managed to die. Edimax to the rescue, I ordered my second adapter and gave it to her when it came it. Not very technical, she managed to install the device and drivers and configure it for her home WIFI network. This makes the third one I've ordered. Not due to a failed interface, but a desire to have my desktop system wireless. I decided to move my cable modem/WIFI router combination to another room rather than were my home office is located. So I installed this is my desktop system and now it's off and running wireless. Eventually I will be setting up another system for my younger son and it to will have one of these and be wireless as well. A few months have past and I'm continuing on my process of making all the devices in the house wireless. Been doing some reading and was wanting to get more speed out of my wireless connection on my primary desktop. As it stands, it this Edimax has plenty of speed for browsing, YouTube videos and most of the time Streaming Videos. I do a lot of remote desktop to work and on occasion I was getting some lagging and have upgraded this one to an Inamax AC1200 which I will review over there. I've moved this one on the another system in the house. Great performer and never misses a step.

Works with El Capitan

As of 09/06/2016, the Edimax N150 (Model #: EW-7811Un) is Mac compatible under OS 10.11 El Capitan. I had to call technical support to get it working though. If you're on 10.11, download the latest v1.0.1.4 Mac driver, released on 02/24/2016, at: [...] Unzip the file. Install the driver. Restart your Mac. After restart, plug in the Edimax dongle. Make sure there's a flashing blue LED. You'll see a prompt for an install, I don't recall the name. Input Admin credentials, and in System Preferences > Security make sure to allow installs from all developers. In the menu bar, you should see an icon that looks like a USB flash drive. Once you click on that icon and choose a network and input the password, that will change to a green icon of 5 bars, similar in looks to what you'd see on an iPhone for reception.
