M9- Ethernet backhaul connecting both to Main Router
Is is possible to plug in all Deco units to the main router's LAN ports and get wired ethernet backhaul? I tried this last night and the app couldn't find the 2nd unit. I set it up like this:
1. Setup 1st Deco in app (Checked box for I have a modem/router)
2. Setup 2nd deco upstairs wirelessly first
3. Unplugged 2nd deco and connected ethernet to wall (Main/ISP router's LAN)
4. Switched to AP mode and doesn't work.
And in AP mode, does the mesh tech still work? I want to avoid having multiple SSIDs based on what floor we're on.
I have ensured they are updated.
