Cannot connect iPhone 6S to Apple Airport Extreme Time Machine Guest Network

I recently created Guest Network [Guest 'Name'] with Apple Airport Extreme Time Machine. The existing local area wireless network ['Name' Network] works OK - connections are fast and stable for 3 iMacs and iDevices.

However, the Guest Network will not connect, as reported by iPhone 6S. The iPhone 6S readily connects to the The ['Name' Network] and signal strength for both ['Name'] networks is 3 "bars" as as reported by iPhone 6S. I waited several minutes for the connection [a few feet from Airport Extreme Base Station], but it never happened.

Airport Utility returns the messages

"WI-FI Self-Assigned IP"
 
"Wi-Fi has the self-assigned IP address 169.254.87.8 and will not be able to connect to the Internet"

What am I missing to get the connection working? Different/None IP Address?

Will this work?

A 192.168.xxx.xxx address is usually not self assigned. Self assigned would be 169.254.xxx.xxx addresses, which appear if a computer could not complete DHCP. It could mean that the computer is not using DHCP, but is instead set up with a Static IP in this case.
 
Check to make sure DHCP is enabled by going to System Preferences > Network > select Wi-Fi / Airport > select Advanced. From here, select TCP/IP, and make sure "Configure IPv4" and "Configure IPV6" are set to "Use DHCP" and "Use Automatically" respectively. Then, go to the DNS tab. Clear out any servers you see here by selecting their IP Addresses and clicking the Minus sign.

169.254.x.x is the (almost) universal ip address generated by the PC or device when DHCP negotiation fails and it won't have any internet connectivity.
Is the airport extreme in bridge mode?
What is set for the DHCP options in the router (that is where the problem is)?

Yes, selecting DHCP and NAT allows connection of iPhone 6s to LAN on Guest Network.

Cannot select DNS Server 193.168.0.1 and Minus sign is greyed out.

However, the network Sharp MX-2300N [aka fc2785sharp in Printers and Scanners] is now off-line. Apparently the printer is CAT-5 connected as there is a CAT-5 cable connecting the printer to a wall CAT-5 receptacle.

Restoring the Bridge Mode reconnects the printer- without Guest Network connection as before.

In both conditions, the IP/LAN IP address is 192.168.0.13.

So, maybe cannot have both Printer & Guest Network? Hope I somehow can!!

If so not, that explains why the Guest Network has not been working - likely since the printer was installed.
"Cannot select DNS Server 193.168.0.1"  It should be 192.168.0.1
But; no, I general, Guest networks are isolated from the main LAN so you get to choose which you want, Guest or printer.
