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. 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.
Otherwise it just installs the driver and leaves Windows to manage the connection.
I recommend using the Intel ProSet software, which requires you choose the custom install when installing the WiFi drivers.
The WiFi and Bluetooth drivers were easy to find, though they appear to just be stock Intel drivers anyway. 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. If you don't want Bluetooth you don't need to connect the USB header or port. 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. It comes with the USB header cable which is used to connect Bluetooth. Once the bracket is secured it's rock stable. It fits snugly enough in the slot, but it still needs to be secured.
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. 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. I highly recommend this product, plus, the antenna has a magnet on the base, so you can stick it on the PC! Antenna cable is shorter than expected, so you cant set it far from the port, but no biggie Since turning it to only 2.4 I have had 0 problems.If you have any questions, feel free to let me know. My 5G kept dropping, and since it was running on dual-band, this would make the ping drop. Click that and then for the dropdown box on the right I just changed it from dual-band to -options 4- 2.4 GHz b/g. Just focus on the very first option on the left, 802.11a/b/g wireless mode. Once there, go to advanced and there's a list of big words and options. I went into device manager -> Network Adapters -> and then right-click the dual-band wireless and click properties. I looked around the internet and couldn't find anything, so I just tried stuff. Although the drivers weren't updated, I would recommend keeping them installed for maximum efficiency.This did not help me, and I had no idea what to do.
I tried many things, I updated the drivers (the best way to do this is to go into device manager -> Network Adapters -> and then right-click the dual-band wireless and look for an update and install it. Not bad for daily life and browsing and streaming, but for gaming this was not ideal. Once they're on, your wifi signal will go WAY up.Troubleshooting: I had been having some issues with the wifi getting dropped every few seconds or so. It screws onto the two yellow nut looking things on the back where you would expect them to, doesn't matter which is which, just screw them on. Put the PC back together and then make sure everything is good to go and start it up! Wifi kicked on instantly, and the connection was pretty decent.Setup after setup: After you have your computer up and running, it's advisable that you use the antenna that comes with the wireless adapter. You literally plug it into a PCI-e slot on the MB and then connect the USB connector to the MB. The packaging could've been a little more secure, but nothing to worry about! Open it up and it comes with the wireless adapter card, a disk with drivers (didn't need to use), an antenna, a USB connector to plug it into the motherboard, and an instruction manual.Setup: Setup was fairly straight forward. I ordered the product with free shipping, so it arrived in around a week and a half or so.
