Summary: Fast, solid connection but... driver issues. I would get intermittent lag while playing games online. Turns out the driver version available on their website is dated 9/19/2012. If you search for Atheros AR938X drivers, you should be able to get a newer version dated 12/11/2014.
Summary: I had one of these for my HTPC and decided to build my Sister a new computer. She needed wireless, so I bought another one for her. I bought this one because I have had such good luck with mine. Mine picks up a strong signal form the upstairs router.
Summary: After using it for at least a month, this have given me one of my best experiences with my WiFi. It was really easy to install and lightweight. It was about the size of my palm and it was pretty sturdy too.
Summary: Truly a great WiFi card. I picked it up on sale, but after seeing its fast, reliable performance, I'd easily pay full-price.
Pros: Great speed. Plug & Play. The package came with a drivers CD, but I was impressed to see that I didn't need it for my Win8.1 build. I've had this hooked up to my computer for about two weeks now, and I've not had it drop a connection once.
Summary: I have had this less than 3 months, and it has been nothing but a nightmare! I stream games often, and have never had a problem with my previous wireless card. Ever since I switched to this one as an "upgrade", my speeds are slow, constant disconnecting and my streaming has had to stop.
Summary: No lag on any of my games, and I live 2 stories above my router.
Pros: Honestly I wasn't expecting this wifi card to pull in data so well. I got it on sale which is the only reason why I bought it, but I probably would pay $30 for it anyway now I know how well it works. I'm not sure if it's worth to buy if you're planning on going ethernet anyway, but if you need Wi...
Cons: There hasn't been any cons yet but I'll update if anything pops up.
