Typically you’d have the VLAN tag set on the modem (assuming the ISP specified this) the router is on the “LAN” so I’d check that first.
Setting DNS on both modem/router to 1.1.1.1 and 8.8.8.8 will rule out any DNS issues.
Finally is the modem set to bridge mode? Can you connect a wired client to the Internet directly into the modem? ping and traceroute are your friend in this situation.

Thank you!
I have set the vlan tag on the modem.
I have set the DNS on the router.
I can't set the DNS on the modem.
I see in the logs:
You have delegated ipv6-prefixes but haven't assigned them to any interface. Did you forget to set option ip6assign on your LAN-interfaces?
Well... Maybe?! 😂 I have seen this error in the logs before but can't find information on how to do it. Are you familiar with this?
What model is your modem and router? Sounds like you haven’t assigned the IPv6 to the WAN interface? Brand/models of your gear will help troubleshoot. :)
The wired client is another issue, I'm on Linux and pppoe isn't natively supported. It's a huge fuckery, another rabbithole entirely 😑 I'm rookie in this regard
Right. So IPv6 is not yet widely supported, it’s been 25 years coming and STILL we use IPv4, so perhaps to keep things simple, remove/disable IPv6 support for now.
Order of operation;
1) Confirm connection to your ISP on the modem using your PPPoE credentials (username & password). LED lights confining the link.
2) Connect wired and wifi clients to the modem, confirm they both work with DHCP assignment from the modem. Manually set DNS on modem to 1.1.1.1 and 8.8.8.8. You have a link to the internet that is working.
Assuming the above works, next step is to remove the double NAT problem between your modem and router. Few ways to do this, but will try to keep it simple.
3) Check the default IP range used on the DHCP for the modem and your router. Usually this will be 192.168.1.1 and may be the same for both devices. If so this is a problem.
4) Change the DHCP range on one of the devices. Use 10.0.0.1 as the alternative IP address for your router, leave the modem on 192.168.1.1. This solves the double NAT issue.
5) Connect the routers WAN port into a LAN port of the modem. Remember your router is needing a link to the outside hence “WAN” but your modem sees your router as just another client hence “LAN”.
6) Plug a wired client into the router. Can you ping the IP of the router? Can you ping the IP of the modem? Can you ping 1.1.1.1? If so your on the Internet.
