What can I say. I gave this adapter chance, after chance, after chance. I have had a Netgear AC 1200 router for about 2 years before I bought this AC 1200 USB adapter for a new Windows 10 computer I built. I built two Windows 10 computers within a 3 month time span. I built a cheaper, "budget" pc for my little sister as a birthday/college graduation present, and used a less expensive AC USB 3.0 adapter from a brand I have never heard of (brand: Netis, for ~ $45).
For my own personal build, I bought this AC 1200 Netgear USB 3.0 adapter, as I thought it would better go with my Netgear AC1200 wifi router, have better compatibility, and last longer/be better quality, and all the other things you would expect from a known name brand. Boy was I wrong.
Unfortunately, all I did was read reviews from this website, and my other favorite online retailers. Just Google "ac 6210 Windows 10". You will see a ton of other people with horrible issues with this device. For many, the drivers for this adapter completely ruined their Install of Windows 10, causing them to have to do a system restore, or even worse, a fresh install of Windows 10. Yikes! Luckily, for me the worst was just an endless cycle of disconnects and freezes every time I tried to connect to my 5GHz network.
I waited 5 months (since November, it is now March) for Netgear to make new drivers for this considerably expensive piece of hardware. This model has been out since before windows 10 launched, and Hardware/Software developers have had early access to Windows 10 since very early in 2015 (Windows 10 launched for retail sale in July 2015). Now, in March 2016, there are still no usable drivers for this device! I can get on the 5Ghz frequency, but lose/gain the signal every 10-15 seconds. This makes streaming, gaming, or even web browsing difficult (on the browsing side) to impossible (on the streaming/gaming side). I installed an AC wifi card in my laptop and one in my gf's laptop 2 years ago (intel 7260) when I got my Netgear AC1200 router, and have had 0 problems the entire time. The "Netis" 5GHz USB 3.0 router I bought for my sister's PC has had 0 problems (built in August 2015).
All of these computers are accessing the same router. It doesn't matter if I am the only one in the apartment and thus the only one accessing the router or not, I still have a constant signal drop/re-acquisition. Netgear has had a very long time to write good drivers for this device, and they have not. They are a huge company putting out very expensive products, especially compared to their competition. For them to have failed to write usable drivers so that I can use their product as advertised, as it is NAMED and AC wifi adapter, and that I cannot use it to reliably connect to an AC adapter, when I have 2 tablets (android & windows), 3 cell phones (2 android, 1 Windows Phone OS), 2 laptops, and 1 other desktop that have ZERO problems connecting is completely unacceptable.
It took me 90 minutes to write this review, by the way, with all the persistent connection issues. I wrote this using the PC in the picture, with the adapter clearly visible. Yes, I know what I am doing/talking about. Stay away from this one. Give Netis a shot. Cheaper, better antennae, and better DRIVERS
