I've just installed OpenWrt and followed the directions up until it said to ping openwrt.org. That fails with the error message "bad address."
I figure if I can get ping to work I'll be able to reach the rest of the Internet as well.
My router is a Netgear R6350 running OpenWrt 22.03.5, if that helps.

How do you connect to the Internet? By default, OpenWrt uses DHCP on the WAN port.
The message suggests that there is no DNS configured or the configured DNS is not responding.
Please run the following commands (copy-paste the whole block) and paste the output here, using the "Preformatted text </> " button:
Remember to redact passwords, MAC addresses and any public IP addresses you may have
ubus call system board; \
ping -c 2 1.1.1.1; uci export network; \
uci export dhcp; uci export firewall; \
ip -4 addr ; ip -4 ro li tab all ; ip -4 ru; \
ls -l /etc/resolv.* /tmp/resolv.* /tmp/resolv.*/* ; head -n -0 /etc/resolv.* /tmp/resolv.* /tmp/resolv.*/*
I had forgotten to set up the DNS servers. Finally found the place to do it and set them up, and now when I ping openwrt.org I get 100% packet loss. Not ideal.
I tried entering your commands but there's no ubus command. What should I install to get it?
Nothing. If there is no ubus command, you are either not running an official OpenWrt build, a very ancient version of OpenWrt or your installation is broken.
And just to be sure: You need to run these commands on your router, not on your computer.
Oh. Thanks for the clarification; I was trying to run that on my laptop.
In a terminal session enter: ssh root@192.168.1.1 enter your OpenWrt password (likely null at this point).
Should end you up at this screen:

Hope that helps!
Your WAN and LAN are in the same subnet. Change one. Routing 101: every subnet must be different.
Also, don't use a subnet address as an interface address.
The IP address 192.168.1.0 is wrong here and conflicting with the lan IP.
You already have a public IP set in Internet interface, but there are no gateway or dns. Also the additional interfaces do not belong to any firewall zone.
