WiFi internet connectivity issue iPhone 8 Connected to AirPort Time Capsule 802.11ac (network name BZ), which is connected to a new cable modem (just moved to new building/ISP). Internet works fine on other devices (MacBook, tablet). iPhone 8 (iOS 11.4) will connect but says no internet. Airport utility shows active internet connection (see picture). 

I tried restarting phone, forgetting network, and reset network preferences to factory defaults. Still no internet. iPhone will connect to other WiFi networks and gets internet with no problem. Any ideas? Thanks for your help.
Solved myself--Reset default settings on Time Capsule. Setting router mode to DHCP and NAT seemed to be the critical change.
