Archer C7 AC1750 Bridge Mode
I have an Archer C7 AC1750 wireless router which is great but I can't enable bridge mode through my modem, so I need the Archer's DHCP service to be disabled and pass the DHCP from my modem through a LAN cable (not wireless). How can I do that?

It looks like the Archer C7 makes it easy to disable the DHCP server, but there's no way to to make the WAN port act like one of the LAN ports (that is, switch off all firewall/router/NAT gateway features, making it just a bridge). So you'll have to disable the C7's DHCP service, set its LAN port to have an IP address on the NAT private IP subnet that your upstream NAT gateway is providing (what you're calling your "modem" appears to have home gateway features; it's not "just" a modem), and connect a LAN port from your C7 to your "modem".
