I was heading down the wifi radio route as I was just reading this thread, glad you got it sorted. @ogiewon had a good post with a diagram somewhere I found quite useful, explaining good channels to use.
I would try Hubitat on Zigbee channel 15. Put the Hue hubs on channel 20 and 25. As long as you use 20MHz channel width for your 2.4GHz WiFi on channel 11, it should be alright. I would not use Zigbee channel 26, as it is limited to lower power due to FCC regulations, IIRC.

Zigbee Channel 11 is often not very ideal, as it conflicts with 2.4GHz WiFi channel 1. What WiFi channel(s) are being used by your home network?
It is always best to make sure your 2.4GHz WiFi network is only using channels 1, 6, and/or 11, with a 20MHz channel width. This will create three distinct non-overlapping gaps that Zigbee channels 15, 20, and 25 will work with minimal interference.

This is not to say that 2.4GHz WiFi interference is the source of your issues. Howe…
