Xiaomi Wifi Router 3G - 18.06.x / Wifi issues 2.4GHz + 5GHz

Anyone having issues with speed on the 5GHZ? I noticed that when I do a speedtest using the 5Ghz radio I can’t get downloads in excess of 100Mbps. This is the same for both 18.06.2 and the master branch. When I perform the exact same test using the same settings (down to the channel) on a Hootoo ND-001 (strong 1200 clone which uses the same wireless chipset and SoC) I get the full 200Mbps of my Internet. Additionally when I try this test over wired Ethernet on the Xiaomi it also gives me the full 200Mbps speed. For some reason I’m capped at 100Mbps though over wireless.

I’m trying to use the router as a dumb AP, but it’s useless if I can’t get the full speed. Does anyone else see this problem on theirs?
