5 out of 5 eggsWorks on Mac

Pros: Got it to fix my friend's problem with his air port on his mac. After installing the drivers which I downloaded and followed the clear instructions, it worked well.

Cons: The range is less than the wifi in my phone but the phone only has one bar when the adapter can't see any wifi.

Other Thoughts: It's a nice size device to just leave in all the time.

5 out of 5 eggsI'm impressed

Pros: Tiny, cheap, plug and play with Win8.1 (recognized immediately even during setup process, no 3rd party drivers required), surprisingly good reception for something that's so small.

Cons: None that I can tell!

Other Thoughts: Admittedly my wifi router is only about 15 feet away from this gidget but I'm still impressed that an antenna that's so small works at all!

5 out of 5 eggsExactly what I wanted for my Pi

Pros: Worked great with Ubuntu. Used this with one of my RasPi's for monitoring temp in the kegerator. Was always connected. Does what I needed it to. Did not test speed as that I am only using it for a light weight web page. graphs and stuff.

Cons: Nonz cons

1 out of 5 eggsDifficult to work with

Pros: Small profile, cheap, includes software to make it an access point

Cons: Very difficult to interpret instructions (language problems and outdated 4-year old functionality). Could not get it to work on three different Windows 7 computers although it would detect my network on two of them but only on some of the screens and only for a few seconds. In all cases an old Linksys adapter would start working within a few seconds of being plugged in because Windows recognized it and installed a driver. Support is non-existent.

Other Thoughts: Life is too short to spend a day and a half trying to get an apparently functional device to work on three computers with adequate signal available and not having any success. The device driver came from Realtek, and all three of the computers have Realtek LAN chips.

Manufacturer Response:

Dear Frank,

We are sorry that EW-7811Un does not work well for you.

It looks like the driver of the wireless adapter has been installed properly in your windows 7 computer so that they can see your wireless network. In the case that the EW-7811Un can detect your network sometimes and can not detect your network in a few seconds, the wireless adapter could be faulty.

Please feel free to contact our tech support at (408)988-6092 or write an email to " support@edimax.us " directly.

Best regards,
Edimax Customer Service Team

5 out of 5 eggsThe title mentions it is easy

Pros: Bought this to replace a device from a major networking vendor which you could set your watch by to lose its connection every two to five minutes and never getting beyond four bars. Am thinking about putting it under my tire for the 4th of July and running it over and showing them what I and others think of their device.

As soon as I plugged this into the front of my case and the blue light started flashing like crazy...I knew I made the right decision on purchasing this. Put the disk into the drive...pointed Windows 7 to it and less than two minutes later...I was at five bars. The real test came on whether or not I could keep a connection active when I started up BlueStacks and played my online game. Not only did the connection stay active no matter what I did...but I have not needed to continuously disconnect/reconnect every couple of minutes just to play my game or do anything online.

Having it only about a day and not having the problems I've been accustomed to...may purchase at least one more of these to keep around or to give away to someone who is fooled by a vastly overpriced piece of piece of garbage made by a famous name.

Cons: The only thing I would call a con would be its size. It's barely noticeable in my front USB port. Very easy to lose it if you don't pay attention. My USB PC bluetooth radios are bigger than this.

Other Thoughts: The price was right with 20% off with a promo code. My connection is now stable and at full strength. It does exactly what I and others needed. Will be purchasing at least one more to keep around and will make sure I recommend it to others who discover the name of a major networking vendor doesn't mean they don't put out vastly overpriced piece of garbage.

1 out of 5 eggsTERRIBLE

Pros: Very small and a low price

Cons: Loses almost 99% bandwidth it is terrible I have 30 Mbps download internet and the max that i got is 30 kbps only being 4 feet away from the router.
If you want to do anything on the internet or gaming do not get this product

Manufacturer Response:

Dear Mr. Lopez,

We are sorry that EW-7811Un does not work well for you.

Maybe the wireless adapter is broken or there is some interference from other devices.

Please feel free to contact our tech support at (408)988-6092 or write an email to " support@edimax.us " directly.

Other Thoughts: None

3 out of 5 eggsSlow

Pros: None. I need to get rid of these now, they are worthless.

Cons: This is extremely slow when paired with XBMC on Raspberry Pi.

I regret purchasing this and not the 300mbps adapter.

Manufacturer Response:

Dear customer,

We are sorry that EW-7811Un does not work well with your Raspberry Pi.

Our EW-7811Un uses 2.4Ghz frequency. Therefore, you may try switch the 2.4Ghz channel number of your WiFi router. It may have better throughput.

Please feel free to contact our tech support at (408)988-6092 or write an email to " support@edimax.us " directly.

Best regards,
