2 out of 5 eggsNo ESD protection

Pros: Works well before it fries. Excellent driver support in even basic Linux installations

Cons: No ESD (electro-static discharge) protection means fried adapter if indoor humidity is too low. I touched the enclosure of my PC and the external ESD ended up frying this adapter and the same happened to 2 other Edimax adapters in separate hardware configurations.

Other Thoughts: It's cheap and works well in perfect environments, but you've been warned

1 out of 5 eggsWell Packaged

Pros: Whoever did the copy writing for the item took incredible shortcuts.
I own it.

Cons: The adapter is said to be "Linux compatible". It's only partly true so that means it's only partly a lie. I contacted the manufacturer's rep and others to find that my level of expertise in updating my kernel is insufficient to actually USE the adapter for connecting my Linux Mint OS to the internet-or any other wireless router.

Other Thoughts: I'm keeping it in case the one running my Windows 7 machine screws the pooch.

Manufacturer Response:

5 out of 5 eggsWiFi Adapter

Pros: Distance is very good with this. I did have to use the extension usb cable to get the best signal, but, that is what it is for. My old G adapter would only get 18Mbps. I can get 120Mbps with this one to my N router. If I upgrade to an AC router, I would expect this to go up quite a bit.

Easy install, using the CD drivers that came with it. Worked right out of the box with no problems.

Cons: So far none.

3 out of 5 eggsGreat if....

Pros: Works really well for wireless N. It works almost as well as the tl-wn772 for wireless N.

It looks really cool and uses a dock which is included as well.

I would of kept it IF I only needed a wireless N device.

Cons: The annoyingly bright blue led light that faces you. A flashing light does not make me think it's working but rather wondering how to block it.

The installation for this is horrible. Has no plug in play usb support, you must install the disc software first. Oh by the way don't lose that disc because you'll never be able to get the driver again period. That's right no drivers, wireless client software, or anything else on their website. Just some more useless pdfs of the papers you get in the box. If you plugged in hoping for plug and play support you now get to restart.

So if you installed the driver with no adapter software which did work on windows 7 x64. Now you will soon realise how do I connect to the 5ghz band. Well I could see it wifi analyzer programs but never through windows. Not sure if I could of done something else but according the the software I was using it got a lower 5ghz signal than my samsung galaxy s2 phone.

Other Thoughts: It is draft ac but should theoretically work close to the same as other ac adapters. I think the antennas for the ac are weaker than the wireless N ones.

Manufacturer Response:

Dear customer,

We appreciate your feedbacks about our EW-7811UAC.

The blue LED indicates that there are traffic through the wireless adapter. Maybe you have a vertical USB connector so that the LED of the wireless adapter faces you. If you have a USB extension cord, you may use such extension cable so that the wireless adapter does not need to plug into to the vertical USB port in your computer.

EW-7811UAC is our newest AC adapter so that the driver is not included in Windows 7. If the CD disk is damaged, users can download the driver from our HQ site at or from our USA site at

EW-7811UAC has 4dbi antenna for 2.4Ghz network up to 150mbps and 6dbi antenna for 5Ghz network up to 433Mbps. tl-wn772 is a 2.4Ghz adapter with 4dbi antenna up to 150mbps.

If you need any further assistance, please contact our tech support at (408)988-6092 or write an email to " ". Our tech support team will more than happy to assist you.

Best regards,
Edimax Tech Support Team
