I knocked two stars off for the following reasons... 1. You can get better speeds on 802.11ac with a different card (if you're using an AP that is 4x4 capable) 2. The included antennas are mediocre at best (I was able to get an additional 100Mbps using my ASUS PCE-AC88 antenna array, which is mountable with a magnetic base)
My access point is a UniFi nanoHD which has 4x4 MU-MIMO 802.11ac. My previous network card was a ASUS PCE-AC88 which is also capable of 4x4 802.11ac. I bought this knowing that I wouldn't be able to take full advantage of it, since my access point is not WiFi 6 capable. However, I was looking to add Bluetooth 5.0 to my tower PC and I thought I would "future proof" myself a little with this card for when I did get a WiFi 6 AP.
Long story short, I went back to the ASUS PCE-AC88. I was pulling down about ~200Mbps with this card (after upgrading the antenna), and my ASUS PCE-AC88 could pull down ~350Mbps. That being said, I also decided to keep this card for the Bluetooth 5.0 capabilities. I now have both cards installed and the wireless network interface of this card disabled through device manager.
I'm sure if I had a WiFi 6 AP I could have realized better speeds, but I'm not there yet and the 802.11ac aspects of this card weren't as good as my previous ASUS. I'll keep this card around for the Bluetooth 5.0 features and maybe I'll try it again once I have a WiFi 6 AP.
