Gigabyte GC-WB867D-I REV 4.2/Wireless AC/B/G/N Band Dual Frequency 2.4Ghz/5.8Ghz Expansion Card,blue

Was going to get the v2.1 version with the 7260 card in it, but this became available on the exact day I went to order it, so I decided to chance it, and haven't been disappointed. In the three weeks I've had it, it's been very reliable and fast.The card has only a full height bracket, so unless you feel like modifying the bracket to make it fit a half height case, I would advise finding a different card.The antenna cable is only about 2.5', so if your PC is on the floor, the antenna won't go much higher than the top of your desk surface.Installation of the card is no problem. It fits snugly enough in the slot, but it still needs to be secured. Once the bracket is secured it's rock stable. It comes with the USB header cable which is used to connect Bluetooth. It also has a convenient USB port (you need your own A-to-A cable for this) to plug into if you don't have a free USB header to enable Bluetooth. If you don't want Bluetooth you don't need to connect the USB header or port. You have to connect one or the other for Bluetooth to work though.Drivers are included on a CD, though I didn't use it and just downloaded from Gigabyte's site. The WiFi and Bluetooth drivers were easy to find, though they appear to just be stock Intel drivers anyway. I recommend using the Intel ProSet software, which requires you choose the custom install when installing the WiFi drivers. Otherwise it just installs the driver and leaves Windows to manage the connection. The ProSet software works better than letting Windows manage it, plus it gives you a tray icon that when you hover your mouse it will show the SSID, signal strength (which is also conveyed by the icon), link speed (nice!), and Internet status.Performance has been great when connected to an ASUS RT-AC68U on 5GHz only at about 40 feet through 2 walls. I can't quite manage the full 667MHz link speed (though another three feet closer and I can, but I can't keep the antenna there), but I still see 585Mbps 100% of the time. File transfers between this PC and a Gigabit wired PC are about 40-60MB/s on 2TB 5400RPM drives. So I'm peaking at about 480Mbps transfer rate on file transfers, which is acceptable, considering the rotational drives and network overhead. My Internet peaks at only 150Mbps, so I have no issues with Internet. Ping times are the same as my Gigabit wired PC to within three tenths of a millisecond, and I've not had a single loss of connection. I frequently access my PC from my phone via VPN, and this is usually where I would see problems on other wireless devices, yet the connection is stable, even for streaming 1080p media over the VPN to my phone.This card also supports both the lower and higher channels for 5GHz AC. I bought this card to replace an ASUS card that wouldn't connect to the high channels for 5GHz AC, as it turned out it wasn't supported.All in all, it has been exactly what I needed. I don't need AC1900 speeds, so for 1/3 the price of those cards this works perfectly. At about half the speed of Gigabit, it's more than acceptable. Great setup.

After using the Gigabyte Bluetooth/WiFi Expansion Card for a couple weeks, I can say that this card does the job very well.Pros: easy install, plug n play, great signal strength, bluetooth works fine, magnetic desk/pc mount, price for performanceCons: I have had no issues with it, so noneOther: I built a computer for gaming and streaming performance, and was worried about signal strength since I was unable to drill a hole through my wall for an ethernet connection. There has been no lag, although I am not far from my router, about 8-10 feet on the other side of a wall. I actually have done some testing, and found that my download speed with this thing was the same/if not a little better than an ethernet cable. For the price, this was the best WiFi card I could find, and it seems to go out of stock everywhere quickly. The bluetooth also worked instantly with my Jambox Mini portable speaker and Galaxy S6. I am not sure about the distance factor for either since that wasn't a concern for me. 10/10, would recommend.Edit: If you are having any problems, make sure to download the latest drivers from the Gigabyte website. Also, any bluetooth audio problems with your phone should be fixed by getting the Qualcomm Atheros BlueTooth driver Version V8.0.1.326

The Gigabyte GC-WB867D-I Rev 4.2 has met my expectations, and perhaps exceeded them.Pros:- Great range; using from upstairs while the router is downstairs through a couple walls and a floor.- Easy installation; While this is technically an adapter for a laptop component, it comes already setup in the box, just plug it in to a PCIe slot.- Drivers are good if you get them from the right source; Using Intel's driver detection utility will make installation a breeze and get you the latest, most compatible version of the driver software for this adapter.- Speeds and ping are decreased; after being relegated from using ethernet to using a USB wireless adapter, the effects of said switch were disheartening. Moving to this adapter has made the shift to wireless a lot more bearable.- Bluetooth 4.2 support; I've tested file transferring from my Galaxy S4 as well as using my Wii Remote (Wii Motion Plus vers.) and both worked with no difficulties. Great pick for Wii emulation with proper hardware.- The magnet on the antenna is commendable; while not the greatest antenna design, it is foldable so it can lay flat on your PC case's side, or upright on top of your computer as well.- PCIe compatible; it can plug into any available PCIe slot on your motherboard.- Well packaged; packaged in a way that the card doesn't move around. Anti-static bag.Cons:- Included driver disc is way outdated, which is not surprising.- Drivers on Gigabyte's site are also outdated, I find Intel's drivers to be better.- Antenna might be ugly for those trying to have a slick looking rig; you can cheaply buy a dual antenna or two antennas to go on the back of this card, though.- Requires a USB Header free for Bluetooth usage; didn't affect me, but I'm sure it might make some people have a different opinion of this card.- Intel's drivers may install software that some will consider bloatware if they don't use an advance installation method.
