Experience: 1 Years



finally can get advertised ISP speeds.
Bought to replace old trendnet. Speeds almost tripled on the 5Ghz band.

Experience: 5 Months

Decent for the price


--Decent and consistent speed
-Easy setup
-Signal strength is good
-Connection strength can be choppy if you're router is some distance away or is blocked by physical objects (walls, floors)
Only use this to connect to my printer or if I take my pc with me to travel. I would recommend getting a powerline if you picky about speed. Other than that, it hasnt let me down yet.

Experience: 1 Years

What can I say? It works!


-3 Antennas
-Excellent range
-Transfer speeds are very good
-antennas must be kept on
-get in your way sometimes
No problems. Was pleased with the ease of use of this wifi card. Happy with performance as well!

Experience: 3 Weeks

Not great signal, but does it's job. Verified OwnerVerified Owner


-Maintains connection well
-No hassle to use
-Weak signal strength
This definitely worked right from the outset, however I found my download speeds had been reduced to roughly a third of what they were while using a wireless bridge adapter so I switched back to the bridge.

Still a simple solution when you can't connect to ethernet and perhaps in a building without metal framing it would work better.

Experience: 3 Years

2-3 Years of use and here is my review


Average NIC (network interface card)
The 2.5Ghz/5Ghz performance is real
It struggles to perform when you are, I would say, a floor below or above the main modem/router.
So I have been using this card for more than 3 years and those 3+ years I have used it in many houses. Yup, I have moved 4x in my 3+ years. Haha, in fact 4 places. This device works well for me, if your main router is on the same floor as your desktop computer. I don't own a house, im just a tenant, my gaming PC has this card attached to it and thats how I do my internet. I stream a lot, online games a lot. I don't watch TV no more so a reliable internet connection is what I want.This latest house I am living, this device is struggling honestly. It has network disconnections more often. Yeah, I never had problems, with my other houses in the past. Now, I can't play my online games. Maybe the new place I'm staying is not build for WIFI lols. I'm talking about using Steam and, if you're a gamer then you know what im talking about. So yeah, this is a good product if you are near the source router. But if you are floor below or above, good luck with that. Im thinking of using power internet nowadays.

Experience: 2 Days

Good wireless PCI-E Verified OwnerVerified Owner


Easy setup
Strong signal, no lag
The installation CD is not working, have to download driver and software online
I would only recommend this card if you need wifi from short distance.
Singal Strength has been high : 90%-100%, and the speed jumps from 6Mps to 300Mps

El Mahdi_Z
Experience: 3 Months

great product


dual band, 3 antennas.
none for me
I don't know if the 3 antennas help, but in my case the card works as excepted, so no complaints.

Experience: 5 Months


The speeds and the signal strength is very good... if you know how to line it up right.
The arrangement of the antennas(sp?) is very important. If you buy this an install it and find it difficult to get a good signal, play around with the antennas and you'll get some progress.
Not sure why wireless network cards are so finicky for desktops, but you just gotta cross your fingers and just hope for the best with these things. I have to admit, I was surprised by these things being the weakest components of all the things I did my research on.
Good luck!
