Replaced my eero router setup with an AX11000 (yes, the big dog TP Link).  I set it up with all the same settings as my eero.  Half of my Kasa switches took to the new router with no issue.  The other half, nope.  Did the 5 second reset and now they just blink green and amber WiFi.  

It's not a distance issue, as the further ones from the router are all connected fine.  Is there an easy fix?  I'm about to take this router back as it has a more serious issue that may not be fixable (DHCP issue when trying to use my Pi-hole server as my DNS...have another thread open on that).
