RAX200: poor WIFI performance
not sure why my primary post was deleted... I bought the RAX200 thinking I would have nice perf with my iPhone 11 Pro max and my iPhone 11, although I managed to get 800Mbps max maybe one time,...

But I can't believe that a 802.11ax is getting worst performance than a old 802.11ac router, that's make no sense for me.--If you're getting 590-700mbps and so is your other gear, its doing what it should. If you had a 3x3 or 4x4 antenna ax device (I don't know of any made other than routers), your speeds would be faster. Or even a 2x2 that supports 160hz wide channels. (which the iphone doesn't). Here's how it works: 4800mbps= 160 hz and 4x4 antenna. Iphone has only 80 hz support so max connection would be 2400mbps IF it had a 4x4 antenna. with a 2x2 antenna, max connection would be 1200mbps. Wireless AC was fairly refined by the time wireless AX came out so they were getting the best out of them because it'd been optimized through several generations. Wireless AX is first generation and just passed certification 1-2 months ago. I expect optimizations from both the router and wireless manufacturers.
I actually don't know what the settings (channels wide) for 5Ghz
as you can see on the screenshot, 2.4Ghz I have a option "Enable 20/40 Mhz coexistence" but no other option and nothing at all for 5Ghz---Thats correct for the 2.4ghz. The 5ghz channel width is set by the "up to ***** speed. 20hz=600, 40hz=1200, 80hz=2400, 160hz=4800)
I found some screenshot online but my web interface since different, for example in "Mode" it won't actually tell me the mode but just "up to 4800Mbps for the first 5Ghz channels and 2400Mbps" for the second (not sure why they are different value by the way, can both 5Ghz channels work in the same mode? Not sure why you can't set the 2nd 5ghz radio for 4800mbps. I have the rax200 and I can set it for 4800mbps. It does require the use of dfs frequencies to allow. What region are you set in? Some don't allow dfs frequencies. Have you tried setting it up? I think its default is 2400mbps for the 2nd band.PS , thanks for the articles, quiet interesting, didnt have time to read all but will definitily read that today

Last quick question and I'm probably saying something stupid, but why I can't see any 80Mhz channel but only 20MHz whatever mode I use
e.g 100,104,108,112,116,120,124,128 from what I remeber they are 20 Mhz channels no?
nevermind that was very dumb question actually.

this is what webGUI current design.
all these shown are 20Mhz band which will be used for when your devices can only support 20MHz band (legacy devices) or backward compatible channel when you're away from RAX200.
But I don't get it why I only have this channel avalible, my MacBook Pro / my iPhone, and other clients are able to handle 80Mhz

160hz channels needs to use dfs channels. which is the 50-144 channels. You might select channel 100 but it has overlap.
