I never thought I'd say this, but... I need gigabit WiFi speeds, or at least close to it to not bottleneck my connection. I have a Netgear Nighthawk X4S router, and its keeping up with my connection, but my WiFi adapter is not. So, I'm looking for a USB 3.0 WiFi adapter that can maintain 400 mbps easily on 802.11ac 5 GHz. The adapter is not going to be far from the router, so range isn't an issue. I can not use a Cat6 cable to my PC because my motherboard's RJ45 port is broken.
