YouHua WR1200JS 5Ghz slow speeds

I have three of these units CAT6 hardwired, running as simple access points, in my home. My hardwired speeds are fine on these devices (525/25). However, my WiFi speeds are pretty bad, at only 150/25. I'm fairly certain, it is a driver issue.

I'm currently running, OPENWRT Firmware 19.07.2 from here:

I also have webcams connected on these, using mjpg-streamer, so using the latest openwrt firmware is not an option right now since the current mjpg-streamer crashes.

That being said, anyone using the YouHua WR1200JS can point me to firmware for this device with updated wireless drivers that are capable of full wireless speeds?

        option hwmode '11a'
        option path 'pci0000:00/0000:00:01.0/0000:02:00.0'
        option htmode 'VHT80'
        option txpower '15'
        option channel '44'

config wifi-iface 'default_radio1'
        option device 'radio1'
        option network 'lan'
        option mode 'ap'
        option ssid 'sr_guy-5Ghz-Den'
        option encryption 'psk2'
        option key 'password'

No problems with my 2 * WR1200JS
