WAN Not connected

I can’t access internet and I don’t know why

I have disable all Wifi at this moment. I just want to go from LAN port over WAN port to another router (who is connected to internet).

I have installed a SSD disk but not configure anything yet

Any suggestions how I should find the problem ?

First you need to find out why the WAN interface does not have an IP address. Should it get one from the DHCP server on the other router, or is it possible that you need to configure it manually?

Hi Thanks for reply. The solution was to check “Use default gateway” then I get my WAN to work.
Don’t know why but now I have connection from LAN to WAN
