This product works very well... when it decides to actually work... When I initially installed the product, it worked like a charm. After the first day or so, it began to frequently disconnect(multiple times per day). Once disconnected, it would not be able to re-connect to the network even though it was showing a strong signal strength the entire time. Sometimes it would reconnect on its own in a few minutes, other times I had to either unplug the adapter and plug it back in, and sometimes I even had to reinstall the driver for it to work again. I work in the IT industry, so I know quite a bit about troubleshooting faulty hardware/software. I tried changing some settings in the device manager, searching for new updated drivers, and modifying router/network settings but to no avail. I tried searching the Netgear forums, as well as other tech support forums, and discovered this issue is very widespread and has no known solution.

Unfortunately, I saw on Newegg that this product had received overwhelmingly poor reviews with a majority of reviewers reporting they faced the exact same issue with frequent disconnects and have not been given any resolution from Netgear. It's never a good sign when you google the product name (Netgear A6200) and a popular related search for it is "Netgear A6200 keeps disconnecting".

To be fair, I was able to get it to stay connected perfectly with the 2.4Ghz band (orange light)...which is why I gave 2 stars.... but I bought this because I wanted a DUAL-BAND adapter. It seems to have terrible issues maintaining a stable connection to the 5Ghz band (blue light) and will give you nightmares trying to reconnect to that same network even though it is showing maximum signal strength.

I returned this for a refund and bought a TP-Link Archer T4UH(similar price point) and it has worked perfectly for me since, and is actually able to stay connected to the 5Ghz band like it is supposed to...

I just got the WNDA4100 yesterday and here are my first impressions. First, I am using the WNDR4500 Netgear router. I have been using it for about 3 months and have been very happy with the router. It has been very reliable since the last firmware update (v1.0.1.6). My router and PC are on opposite corners of the house, about 60ft and 8 walls. I know 5GHz does not do well penetrating walls but I wanted to see what it could do. My laptop with 802.11n and a single antenna at the same distance gets 72Mbps, the max it can get with 1 antenna. My desktop PC (Dell Inspiron 531/Windows 7) has a 802.11g PCI card adapter and gets 54Mbps. I wanted to upgrade since I have been working on some large video files that take 15mins or more to backup. I also wanted to try out 802.11a (5GHz). With 3 antennas in the adapter 2.4GHz max is 216Mbps and 5GHz max is 450Mbps. The WNDA4100 is a large USB adapter. It won't fit in my PC directly so I had to use the connector cable. Using the cable is a good idea since I could easily hit the adapter if it was plugged in upfront. I installed the software from CD and everything installed correctly. The router has an SSID for 2.4GHz and one for 5GHz. I disconnected from the 2.4GHz SSID and connected to the 5GHz SSID. I was not getting the expected performance. I was getting 54Mbps. I started inSSIDer to see what was going on. I rebooted and it did not fix it. I was finally able to connect at 162Mbps. I think inSSIDer was causing problems with the connection. I was only getting 3 bars (-80db) with 5GHz so that explained the 162Mbps and proved my concern about 5GHz penetrating walls. I then disconnected at 5GHz and connected at 2.4GHz. I got 4 bars (-60db) and connected at 216Mbps, the max. I then tried to ftp a 1G file to my NAS server.Read more ›

Size: AC1200 Beamforming+ Vine Customer Review of Free Product ( What's this? )
The NETGEAR A6210 comes with a desktop dock with a nonslip bottom that is useful to place the adapter in different positions, while looking for the best one to catch the strongest signal. It also includes a disc with the NETGEAR Genie software making the setup easy. The software can be also downloaded from the NETGEAR website. For the purpose of this review, I double checked and only drivers for the Windows OS are provided.

The most important part during setup is `not' to plug the adapter until the software asks you to do so. Other than that, the setup process is smoothly and easy.

The NETGEAR A6210 USB 3.0 interface is backward compatible with USB 2.0, and with 802.11 a/b/g/n routers.

I own a few wireless adapters and I must confess that I'm impressed with this adapter because of how fast and steady its signal is. In the same laptop I used to get speeds between 108 Mbps and 162 Mbps with another ac Wi-Fi adapter with a USB 2.0 interface, now, with the NETGEAR A6210 I'm getting between 263 Mbps and 300 Mbps, mostly the later. Very steady and so far no hiccups. This is from a room that is exactly 30 feet from the router, and two floors above of it. Of course, the speed will also depends of the router one is using and the strength of the Internet service said router is connected to.

So, if you are in the market for a Wi-Fi adapter, I highly recommend the NETGEAR A6210.

~Highlights~
***** Convenient Design
***** Lightning Fast
***** Reliable
***** Durable
***** Hinged USB Connection

I've tried several different USB Wifi adapters over the past couple of years (Linksys, Belkin, Startech, Netgear), and of all of them, the Netgear ones have been the best by far. They are both the most reliable and the most durable. The AC1200 Wi-Fi USB Adapter High Gain is better than even my previous Netgear adapter, with an even MORE durable design and a hinged USB connector! No more concerns about breaking it where the USB connector attaches to the adapter! Netgear has made that a thing of the past. It is at least as fast as my Linksys AC1200 and my Startech AC1200 adapters, yet more reliable than either of them.

If you want to make an investment on an adapter that will both last and be reliable, you can't lose with the Netgear AC1200. It outperforms the rest by a wide margin, without being more expensive. I highly recommend this for anyone with a USB 3.0 computer, AC band availability, and only a N-band adapter built into your system. This will speed things up exponentially, and offer you reliable, fast access to all of your favorite online activities.
