Constantly Disconnects 7/29/2019 10:37:39 PM

Pros: Small, and non obtrusive.

Cons: This thing always gets disconnected. It disconnects every time i restart my computer so the browser pages do not load. I always have to disconnect it and reconnect to network. Theres a 50/50 chance it prints to a network printer. It usually shows that printer is offline when it isn't - this is fixed by restarting the computer everytime i need to print something. Just a horrible user experience. Advice: just shell out the extra cash for a legitimate network card.

Overall Review: I wish the money i spent on this thing was spent a legitimate network card.

Comically Bad 3/18/2019 4:35:33 PM

Pros: It's low profile

Cons: -It constantly disconnects from the internet.
-It's simply not reliable

Overall Review: -I used this for about 2 years before I was finally able to hook up Ethernet. I was a fool and purchased a MoBo without anything but ethernet.

broke in a week. 10/26/2018 8:52:34 PM

Pros: cheap.

Cons: oh man where do I start with this thing. wifi connection dropouts when my desktop was literally beside the router, it was terrifyingly slow. like, the highest connection speed it maintained (acc to windows 10) was 72 Mbps. no, thats not downloading anything at 72 megabytes a second, it was like maybe 112 kilobytes per second. this thing is really, really just terrible. please read other for my recommendation on what to actually get

Overall Review: just go with the Fenvi usb wifi adapter. thats all you have to type in the search. norm its like $50, but they almost always are on sale for under $20. it's black and yellow and has 2 antennas (that are dope)

We are not sure whether there is any WiFi interference nearby.
This nano adapter has a very short antenna wire inside. Therefore, a wireless adapter with external antennas can work better in such an environment.

It is also possible the adapter is defective. We have 2 years warranty for all of our products.

3 Strikes. I've lost confidence in this brand. 10/22/2018 4:56:31 PM

Pros: I've had good luck with PREVIOUS plug-and-play adapters from Edimax. For some reason the two of these I purchased--AND the replacement I received for one of them--ALL failed.

Cons: Bought two of these adapters. Both triggered "USB Malfunction" errors in Windows on different systems. I unplugged one from the usb port and it felt warm for some odd reason. RMA'd one of the two; when I received the replacement, I received the same errors. Tested on different PCs and they all simply would not work.

Overall Review: I will NOT be recommending EDIMAX wireless adapters any longer. All 3 units would not work as intended. I can't believe that I got a 3-in-a-row bad batch of them.

Dear customer,

We are sorry for the difficulty you are experiencing.
We appreciate your feedback and would like to help you solve the problem.

We are sorry that the replacement unit did not resolve the issue.
This is odd because all the RMA replacements have passed our tests before shipped to customers.
It seems you are using the adapters with Windows computers. Can you please make sure your computers have the latest Windows update?

For further assistance, please contact our tech support and so we can investigate this for you.
