Setting up TPLink Deco S4 1900 with my Xifinity router

Hi,

I bought 3 used TP-LINK Deco S4 1900 series units to enhance my home network.

This is what I have done so far, but failing at one point.

#Accessed Xfinity router Admin page and enabled Bridge Mode.

#Connected one Deco to an Ethernet port (2) of the Router.

#Restarted the Router

#Restarted the Deco

#Tried setting up the Deco.

# I could create the Master Deco and added SSID .

That moment the Deco goes offline and shows RED .

I tried resetting the Deco and repeated the process. No Go.

# I connected my laptop to the Xfinity (Bridge Mode ) router.

I am getting internet. No issues.

# Swapped the LAN ports.

#Swapped the Network cables / Still no go.

#Google says S4 Deco is compatible with Xfinity.

What am I missing here ? I see DHCP & Routing is automatically disabled when we enable the BRIDGE mode.

Any help ?
