Thanks Cali Cat.  I have done the factory reset on both devices with the same result.  I am not using WPS …. am using the app from each supplier to them set up.  They accept the same SSID and PW for the 2.4 and 5.0 ghz bans separately ….  that doesn't seem to be the issue.  The error message asks if the router utilizes an Access Control List and if it does it gives the MAC address to enter.  I tried to resolve with TMO customer service but got no real help. 

That indicates that the TMO router is not passing back an IP address. Since there is no ACL feature on the TMO router, there is some other compatibility and or setup issue you are having.

You might want to try using ethernet to your extender and try AP mode to see if that works. If it does, then you definitely know the wifi to wifi connection in extender mode is the problem - security standard, wifi standard, etc.

I personally use a mesh system connected via ethernet to the TMO gateway and it works both in AP and  DHCP mode.
