Establish link with the second router in the network.
You can access your second router's interface from your desktop while connected to the router or via Wi-Fi, but there seems to be an issue when trying to reach it from your desktop through the router. I have a modem, an edgerouterX, and a power line adapter. The setup looks like this: port 0 connects to the modem, port 1 is for your desktop, port 2 links to my power line adapter, and port 3 connects to your Dlink router (DIR-880L). You expected it to be as simple as entering the IP assigned to port 2 or 3, but it doesn’t work. The power line adapter includes a scan tool that lets you enter its interface from your desktop without problems, yet the port 3 router doesn’t respond. It’s frustrating. I’ve attached a photo of your Edge RouterX, which shows four connections—two on Eth0, one on lo (what’s lo?), and switch0. Could someone help clarify why you can’t connect to your port 3 router’s UI?
Is the second router configured with NAT? It seems best to use it mainly as an access point. Would you like me to create a network diagram? I can display the port setup on the edge router. You mentioned wanting all devices connected to the same subnet.
lo stands for loopback, so in short: itself. For the main topic. The picture is not all devices connected to the router. It's the routers routing table (Where to send what). Based on your picture, it says that standard gateway is at interface eth0 and that the network 172.103.252.0/26 is at eth0. And a loopback entry, and then the switch0 entry wich states that 192.168.1.0/24 network is connected to interface switch0. And considering you have 4 ports in use, and of the 4 routes there is only 2 that indicates a network means that you are missing one line. So, since everything connected to the edge router needs a network (since it's a router not a switch) this means that there are only routes for two devices. Considering that your PC has internet, the route for the Dlink is missing. What you need to do is to create one LAN for the Dlink, and one LAN between your computer and the router and the LAN between the modem and the edge. And set the routing table for it on the Edge Router for it to work. So: PC network: 192.168.1.0/24 DLink network: 192.168.0.0/24 Modem network: 172.103.252.0/26 And when it's right, your screenshot should show 5 lines instead of 4, one for each device + loopback and standard gateway. EDIT: Brainfart! Is the Switch0 interface a virtual switch? Then double check that the physical interface for Port 3 is included in the switch0. If not, double check that DHCP is disabled on the Dlink and plug the ethernet cable into a LAN port and not the WAN port, because then the for the DLINK will be behind a NAT firewall. Damn, i overcomplicated that way to much...
The two eth0 connections serve distinct purposes. One points to your ISP's next hop, while the other holds the WAN subnet for ISP communication. Since you're using the second router's WAN interface, direct access isn't possible (you're also applying double NAT there). The optimal approach is to give it a fixed LAN address within the 192.168.1.0/24 range, turn off DHCP on router #2, and connect via the LAN port instead.
I configured it as an access point with two Wi-Fi networks, but switching between them wasn't functioning well because neither signal was strong enough to automatically select one. I opted to keep DHCP active so users could choose their preferred connection.
I don't understand what Switch0 interface is. It seems to be a port three that connects to the other upstairs Wi-Fi router labeled "internet." You might want to switch it from Wan to Eth1 and disable DHCP. Will the upstairs router still have internet access?
Access point mode needs to disable NAT/DHCP for that wireless device. For smoother handoffs with moving clients, use identical SSIDs on both APs but on different channels. Adjust the radio power so coverage overlaps just enough, letting the client choose the stronger signal. Keeping DHCP enabled on APs suggests you’re running them as routers, which can cause double-NAT with the upstream router and IP conflicts. When setting up ER-X, did you follow the single WAN setup instructions? The wizard should have guided you through this process. eth0 is linked to your WAN, and switch0 manages LAN ports (like 192.1868.1.0/24) for communication with the WAN. Did you adhere to @beersykins’ recommendations?
