I have a wierd problem. recently I bought a Linksys WRT3200. here is the issue with it:
with original factory firmware I can connect my modem to wan port and access the internet but with OpenWRT firmware my router cannot access the internet nor see my modem.
the wired part is that when I connect my modem to another openwrt router and connect that router lan port to wan port of this WRT3200 everything works fine (I can acces the internet)
I have updated all of my installed packages but it didn't helped with fixing the issue.
I don't think my modem have any issues because I can connect it directly to my motherbaord and my other openWRT router. can you please guide me how can I fix this issue?
I just removed that but I still have the issue. and I don't think It does have anything with the OpenVPN becuase I tested with both on of off vpn state.
you know I think the wan interface cannot start because when the router is connected to my modem directly the "Stop" button next to wan interface in luci is grayed out and when I click "Restart" the "Stop" button is not coming out of grey state. but when I connect wan port to a different openwrt router the "Stop" button comes out of grey state and I can stop the interface. I have tested with different cables and it didn't helped.
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; \
uci export network; \

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 have built firmware from latest version but it behave the same as openwrt original firmware (same issue exist) so I reinstalled the original OpenWRT firmware back (the one provided in the device page).
after that I run the commands and here is output:

This might sound silly, but are you sure that the cable you use to connect roter and modem is working and that the RJ45 "plugs" are looking okay and "snap-in" when you insert them (so you need to press down the plastic "tongue" to remove the plug from the socket?
NO-CARRIER and LOWERLAYERDOWN might denote that something is not connected well (or that some incompatibility makes the router's ethernet NIC fail to establish a link).
I have tested it with different cables but I know the issue does not have anything with the cables because with linksys factory firmware I can connect to my modem and everything works fine. It's really confusing
If your modem has a gigabit port, make sure you're using full 8-wire cable. Old DSL modems were supplied with 4 wire cable which is only good for 100 Mb. It may or may not link at all between two gigabit ports.
I have tried with default configuration and changed my wan mac address but none of them helped.
I wanted to change a lan port to wan port but I don't have "Switch" option in "Network" menu
I dont know maybe these two devices are not compatible with each other
