i used to be able to set up my mox with a 2 and a 5 GHz radio (older systems connected to the slower and newer ones could get the faster one). unfortunately, something changed and the second radio seems to never actually connect to clients.
that’s a great idea. i did that, and there was no effect … (although, with the reset i was able to see the new WPA3 options and the disable management frame protection switch (which also had no effect if on or off))
here are some screen shots to try to answer some of your questions. it seems interesting to me that the radios have different hardware, and that the marvell chip seems not to be working as expected.
i don’t know if this means i need to replace the second radio in some way. thanks for taking the time to look at this and offer your thoughts.
Did you reboot after wifi reset? As peci1 said, it is weird. Maybe your wifi hardware is broken. You should try as a last step, to reset you router to factory settings or better, try to reflash it from latest medkit.
