On Hostname/DNS, under Name Server 1, I set it to 192.168.1.1. And
tried "Use Default Policy", "Only Manually", and "Use Custom
Policy" with Custom Policy Rule set to auto or static. I've also
the entire time had the name sever of 192.168.1.1 in the
/etc/resolv.conf file. The Gateway I set to 192.168.1.1.
Once again, if I unplug the router and plug it back in, with the
above settings DNS does not work until switching to DHCP, then back
to static. If I leave it on static with the above settings, unplug
the router, and then plug it back in, DNS does not work. I can
access the router at 192.168.1.1, but can't go to any web address.
With static settings, unplug the router, reconnect, then do:
ip addr
ip route
cat /etc/resolv.conf | egrep -v "^[[:space:]]*$|^#"
Then,
ping 192.168.1.1
ping 8.8.8.8
ping google.com
then, change to dhcp and back, and repeat all the above, and post all
that back here.

I will plug a Windows laptop with a static IP assigned into the client
bridge router later to see what happens. Once again, I have a DD-WRT
client bridge router with DHCP shut off that I plug the ethernet cable
into. That router talks wirelessly to my main router which is thr DHCP
server and which is connected to the cable modem. But if that were part
of this whole problem, I don't see why Wicked and DHCP work fine and
static addressing doesn't, unless this is some odd bug. Maybe someone
can set a static IP and test, unplug the router and plug it back in and
see if they still have DNS?
