I recently purchased a google nest wifi router and wifi point and want to set up my modem (Archer VR1600v) as a bridge. The modem is already set up (as we were using this as the router for a couple years now) so when I go into Advanced --> Network --> DSL there is already a connection set up. When I try to add a bridge and set the VLAN ID to 2 it says I'm unable to as it's already in use. Below I have linked the steps I've been following to set it up. I don't know if I have to delete anything (didn't want to try just in case something goes wrong) or just use a different VLAN ID Number. Any and all help is appreciated.
