I have a Time Capsule that uses both the 2.4GHz and 5GHz bands. I want to create a Guest Network. When I go to Internet > Internet Connection I change the Connection Sharing to Shared IP Address. When I click on update I receive the following message the dhcp range you have entered conflicts with the wan ip address. Any suggestions on how to resolve this issue will be appreciated. I am willing to reset the defaults if that is an easy solution.
