RAX80 Wi-FI very slow

[MadBrewer62]

I have a RAX80 with firmware V1.0.4.120_1.0.61 the wired wifi is around 896 MBs while the wi-fi on 3 diffrent devices is arounb 280 MBs this is with either 2.4 0r 5 Gh connections, I have swapped aroung channels with no diffreances, It does not matter id QOS is enabled or disabled.  The device os are windows 10, Apple 14, and  Android, which are all arounf 200-280 MBps.  how to I fix this to make it consistent

you told us the operating system you're testing on but not the device you're using. 

That's kind of key as mosts devices are either 1x1 antenna devices or 2x2. 

Also, I'm impressed if you're hitting 280mbps over 2.4ghz. I've been maxing out around that 90-110mbps over the 2.4ghz on a RAXE500, RAX200, and my CAX80. So I'm curious how you're testing your speeds since 2.4ghz is a much slower network.
