Review: Great product however, drivers provided are old and out of date. - Card is easy to install but before you purchase check your motherboard for an open F USB 2.0 head to power the card. Max WIFI speed increased from 58 Mbps per sec. to 144 plus Mbps transmit/receive, a substantial increase. Blue tooth has increase range and I can now walk around my office without losing connection to my headset. What a pleasure that is not being tied to my desk while listening to music and videos. I was disappointed that the provided drivers were out of date and had to search for updated drivers. No link for driver updates were provided. Other than this issue, the card is a definite improvement over the AC 7260 half size wifi/bluetooth 2 x 2 card it replaced. I'm very satisfied with this purchase, the price and ease of installation and no more dropped connection frustrations.
Review: Works in Ubuntu 18.04 LTS - Works in my Linux distro, no setup fuss, just plug it in and fire up the system. My 10 year old BIOS apparently doesn't support booting from PCI express (was hoping to boot a live distro through this card, but I can still boot via onboard USB 2.0).

### ⭐⭐⭐⭐⭐ Did exactly what I bought it for
*by B***D on September 8, 2018*

I bought this card because we recently got an Oculus Rift and the audio intermittently would stop working. I was almost ready to return the rift. I read an article that said it could be an issue with the USB 3 on the motherboard and to try an add-on card. I figured for less than $20 it was worth a shot. I stuck this card in a slot of the Z77 motherboard, plugged the Rift’s USB into it and powered on the PC. So far, so good. The audio has been working correctly. I didn’t install any drivers (Windows 10 PC) and I didn’t plug in the power connector on the card. It is working great. It’s nice having a few extra USB ports as well. Definitely worth the money.
