RAX80 as access point Wi-Fi slow over CenturyLink Fiber - Second attemt at assistance

[brianebrown79]

Stuff I have tried:

•     Updated to most recent firmware (V1.0.1.70_1.0.30)
•     Did a factor restart
•     Turned on/off QOS/WMM
•     Enabled/unenabled Beamforming
•     Enabled/unenabled MU-MIMO
•     I currently have WPA2-PSA security (also tried it with no security)
•     AX enable/disabled (currently is enabled, but do not have anything with an AX card to test)

Bandwidth I have gotten per item/chip:

•     Apple Iphone X - 314 down/450 up
•     Laptop with an Intel AC 7260 chip, connected at 866 Mbps (AC80mhz 2X2) - 250 down/300 up
•     Desktop with an Intel AC 9260 chip, connected at 1.7 Gbps (AC160mhz 2X2) – 480.66 down/902.95 up
•     Desktop wired connection 940 down/up

Anything else you can think of, to help me get closer to the speed I feel I should (866Mbps on Iphone and Laptop, and 940Mbps on Desktop)?
