    Problem resolved.

    I had Orbi cancel the "Parental control" feature.      This gave me back the "Access Control" section on the web administration page.  Once I turned off all the Access Control, the problem went away.   Now I need to learn a bit more on how Orbi's access control works.

I agree.   Those devices that pick up 192.168.2.0/24 work fine.   Some devices are picking up something completely outside that address space.   Those devices can't access internet.     I can't figure out how or why they are picking up wrong IP range.

169.254.x.x/16 is a "Link Local Address" which a device creates for itself when it does not receive an IP address through DHCP:

I would try to connect these devices to the primary WiFi SSID and "see what happens".

Is it possible that Access Control has been enabled on the system?

(perhaps without meaning to.  you laugh, but it has happened to me.  Spent an hour fighting with a device only to find that Access Control was ON and set to "Deny Access to new devices")

    Excellent information!  I didn't know about Link Local Address.

     

    Now to turn off the Access Control.    I enabled Parental Controls for thee trial period.    I found its more trouble than it's worth.    I have requested customer service to turn it off since it's only controlled through the app now.   I tried to get rid of all profiles and make sure everything has full access but my devices still aren't happy on the guest network.   I'll keep messing with it.

    Thanks again for your help and getting me on a potential track to a solution.
