@mrjgardiner well I jinxed it. Had been working fine for a week and then I woke up to every 2.4 GHz device disconnected

@mrjgardiner try turning off AX for 2.4 ( you can leave it on 5 GHz). That seems to have solved it for me

@bowb4myfeet I assume nobody has found a fix yet. I have until August 17th to return this so I was hoping to find a solution. I also had issues with Archer AC4000 so maybe it's time for me to abandon...
