Review: Low expectations, fantastic outcomes so far - I really was expecting these to be a failed purchase. I thought I'd give them a go almost as a novelty... I feel silly now, as they are brilliant. Driver dependency is heavy, don't expect to just plug them in and go as some of the larger clunkier ones would allow with onboard drivers or the ability to use generics. But really it would be kind of giddy to assume otherwise with these things that are so small as to seem unlikely to be effective in any real-world applications. I would do a pro / con, but have no cons.... Perhaps because I just expected the worst, leaving me with nowhere to go but up. - Size: Tiny - I can *almost* close the USB flap on a Dell Duo Convertible with the thing in. I would forget they were in a USB hub if not for the flashing LED. They are practically nonexistent in a tower USB port, front or back. - Reliability: I have used them in odd situations, and have yet for them to be the source of an issue. Mixed NIC environments present the usual hazards, but nothing additional that I've noticed. - Range: Again, I have had low expectations, and so I used them mostly so close to the wireless source that I couldn't judge fairly. They have fit the bill at 25+ feet from the nearest active AP handily. Walls and obstacles have not buggered the connectivity. That's more than I would have expected, your situation may differ. - Price: Cheap, especially considering the awkward situations that they can be used to resolve temporary issues and the time sink potential in those situations if you don't have a quick-and-dirty answer. I will likely keep a small stack of them around indefinitely. So far I have used these in scenarios like: - Emergency connectivity for DNS server mishaps on domains - A replacement for troublesome hard-connections in nearby Win 7 64 workstations - As a makeshift NIC array via a USB hub for Windows 2008 R2 Datacenter servers requiring multiple connections but lacking the hardware - Onboard fail-safe connection (by pluging one into the unusually placed USB slots on Dell and Supermicro server boards, just leaving them there,disabled or otherwise inactive, just in case all other options are bunk) - Near invisible wireless connections on Netbooks, Dell Duo Convertibles, Legacy laptops. I can't attest fully to their cross platform usage yet. But I have several unusual server and wokrstation builds across the SUSE and Ubuntu spectrum that I will certainly be giving them a test on. I have a pretty fair expectation that as long as the drivers install as expected, they will be effective there too... I have used them as a guest captured NIC for Linux and Windows virtual appliances and servers with some success, but as there is a significant abstraction layer there, that doesn't seem like an overall statement about their usage in a standalone environment. So this is one of those times when a shot-in-the-dark actually has paid off in volume... I would (and will) purchase more of them, either for specific applications or more likely as a brilliant addition to my "what if" toolset. If there is a downside, I haven't found it yet...and I have used them in some pretty weird circumstances so far... There may well be better out there, I just stumbled on these, didn't really invest in thorough product research. I grabbed some of these along with other variant wireless and USB NICs for emergencies and peculiar issues. These are the ones I have used almost every time. The rest of that collection of variants remain safely boxed on the shelf.
Review: 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 desertcart’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 desertcart, 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 desertcart 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 desertcart have to do a better job of communicating the good news to their customers.

## Questions & Answers

**Q: dolphin**
A: are you wondering about the dolphin wii emulator then yes it does work you might need driverpack solution 14.0 or above

**Q: Does this work with NOOBS/Raspberry Pi?**
A: Yes, works great.  I didn't use NOOB.  Rather I dd'ed the image directly to the sdcard.  I've used both the vanilla raspian as well as wheezy-octopi raspian images.  Both work fine on the A and B+ models.  To disable the power saving feature of the device do this.  If you don't the rpi will turn the wifi device off after a period of time:vi /etc/modprobe.d/8192cu.confinsert into this file:options 8192cu rtw_power_mgnt=0For static IP addresses, edit /etc/network/interfaces, replace the contents with (adjusting IPs as required):auto loiface lo inet loopbackiface eth0 inet staticaddress 10.100.100.100netmask 255.255.255.0gateway 10.100.100.1auto wlan0allow-hotplug wlan0iface wlan0 inet staticaddress 192.168.100.100netmask 255.255.255.0gateway 192.168.100.1wpa-passphrase yourpassphrasewpa-ssid yourssidThen reboot.  YMMV....

**Q: is this mac compatible?**
A: I just installed it on a white MacBook running 10.8.  Edimax has drivers for all modern Mac OS versions including 10.9.  I was able to connect to my home wireless which uses WPA2-AES.  You don't use the regular drop-down to control like you would with the built in WiFi (Airport) card.  Edimax supplies a program called Wireless Network Utility.  Works fine but not as snazzy as the built in methods.I downloaded the software from here:http://www.edimax.us/html/english/frames/b-download.htm

**Q: What kind of range does this have?**
A: Hard to say, but it is better than the range of my built in Intel(R) PRO/Wireless 3945ABG Network Connection.  When I use my laptop outside on campus, my built in adapter has trouble connecting but this EDIMAX adapter stays connected and with higher bit rates.  This could be because this adapter can see 802.11.n whereas my built in one could not.  I can walk about 40 feet away from any campus building and still have a decent signal with this Edimax adapter.  But range really depends on how powerful your router is, and how many walls/objects the signals have to pass through.

### ⭐⭐⭐⭐⭐ Review
*by D***D on August 3, 2013*

Compré este USB wifi para añadir funcionalidad wireless a mi RPi. Funciona perfectamente en las distribuciones que he probado: Raspbian, XBian y Openelec. Puntos a favor: - Funciona directamente sin necesidad de instalar drivers ni tocar demasiadas configuraciones (en las distros que he probado) - La velocidad és muy aceptable, se puede reproducir videos a 720 por streaming desde otro PC via wifi y no hay saltos (obviamente, en mi caso no había mucha distancia ni paredes por medio). En contra: - Nada me viene a la cabeza ahora mismo
