Kudos to @SpaceAntelope for guiding me in the right direction. I also did some testing with some changes and found the following. ASUS' firmware is poop. Any deviation will make 6GHZ not work!
1. Download firmware 3.0.0.4.388_23759 for your version, install that firmware on ALL the ROUTERS!
2. On node unit, turn off via switch.
3. On MAIN Unit, Factory reset via WPS method. Turn off unit. Push and HOLD WPS button, one light will come on then another. Once that light goes off let your finger off the WPS button. Youll notice the light stays off. Thats OK! Turn the unit back on.
4. On NODE Unit(s), Factory reset via WPS method. Turn off unit. Push and HOLD WPS button, one light will come on then another. Once that light goes off let your finger off the WPS button. Youll notice the light stays off. Thats OK! (Dont turn on unit just yet)
5. Setup main router. Whatever you do, do NOT use/enable SMART CONNECT. Do NOT use anything else other then WPA2 for your 2.4 and 5ghz signals. I dont know why, but these settings have to be as I described. You can mess with pretty much any other setting, but I dont know if that will kill your 6ghz signal at your node. Trail and erro come into play. Also the firmware is VERY finicky. So if 6ghz stops working you may have to repeat the steps above. Again, I dont know why, but that was my experience. ONCE YOU DO ALL OF THAT DISABLE AUTO FIRMWARE UPDATE!
6. Ready for some fun now? Because ASUS' firmware is literal CRAP, do whatever you have to do to get your node to link up to the main router. Once you do the node will be in the spot where you want it or you can place it where you want it. Keep in mind, if you are using a WIRELESS backhaul the 6ghz might not work because it MIGHT be used has your backhaul. Other then that ENJOY your 6ghz on the node now!
UPDATE: After tweaking with it (again) now im regretting it. 6ghz isnt popping up on the node. I factory reset everything (again) and I couldnt quite get the 6ghz to work on the node, but i rebooted the entire network via system settings (within AIMesh) and it seems to work again. This is crazy. I just don't get it but whatever. Fix it ASUS!
I sent asus emails and gave them logs. Now its time to FIX IT!
