I have a TP-Link Deco XE5300 (not recognized in the product model field for this post).

My internet service recently went dark. I disconnected the WAN cable and was trying to continue to use my network locally, but none of the devices plugged into the Ethernet ports were recognized any longer. I even tried plugging my laptop directly into one of the ports (rather than a switch) and it was disconnected, even after rebooting the Deco stations. How do I get the wired LAN devices to be recognized again? I need connectivity between my wired devices and I need DHCP to give IP addresses.
