LAN Settings SXR80 Orbi Pro

Hi - 

I have one SXR80 and 3 SXS80 Orbi Pro devices, and I am trying to set them up.

I have upgraded to the latest firmware on all devices, and seem to have the wireless part of the network working.  I have assigned all IOT devices to WIFI 3 using the IOT VLAN.

However, I cannot seem to get the wired Ethernet ports to work on the router.  I have three ethernet cables plugged into ports 2, 3, and 4 on the router (SXR80), but I cannot seem to get any internet to them.  Ethernet port 1 is used for the WAN connection.  

I have ethernet cables plugged into the port 1 on two of the satellites

On the LAN setup page (Advanced/Setup/LAN setup), there is NO drop-down menu (for LAN 2 and LAN 3) in the VLAN profile field, that comes up for me to change the VLANs for those LAN numbers.   If I try to disable a LAN number is tells me I cannot do that because the LAN is in use.  

What am I missing?
