Hey everyone, I'm not super familiar with networking, so please forgive any mistakes I might make. I'm trying to clarify what's going on with my setup. I currently have internet through a wirelessFibre™ Fixed wireless connection, and everything seems to be working well. The problem started after I upgraded my router to the EdgeRouter X. The interface feels really complex compared to the routers I've used before. I was guided by the ISP for installation, and it all worked fine until now.

Once connected, I switch between wireless and wired connections to devices on my network switch, but I still can't get consistent internet access. I'm struggling to remember the right terms and often lose my train of thought, deleting my sentences because I sound clumsy.

For instance, when setting up a device, I have to manually configure its IP address, subnet mask, DNS settings, and other details before it can connect to the internet. I usually just enter my router's IP (like 192.168.1.1 or 10.1.1.1) and then adjust the settings on the switch. But now I'm confused because my router's IP has changed to something like 192.168.2.1 and 3.1, which doesn't match what I expected.

I'm trying to understand this better because I accidentally disabled internet access by messing with the settings. After a few days of searching for help, someone from the ISP remotely fixed it, but I wasn't able to assist with other issues. I really appreciate any advice or clarification you can provide. Thanks, everyone!

This likely points to a DHCP configuration problem. Regarding your IP range, it’s possible you’re using a double NAT setup where your modem (from your ISP) might include a router itself. This would generate its own network segment. Connecting the router at the edge would require adjusting the network settings. (For example, if 0.1 is active, the router broadcasts 1.1; with 2.1 it broadcasts 3.1, etc.) Many routers default to numbers like 100.1. To resolve this, verify your equipment—check if it’s a modem/router combo. If so, switch it to bridged mode and set the edge router to your desired network (e.g., 0.1 or 1.1). If it’s just a modem, skip that step and adjust the edge router accordingly. For enterprise or business gear, manual configuration is often needed, possibly missing DHCP setup for your specific network. Look for terms like “LAN,” “LAN Network,” or “IP” on the device. You might also check the port being used on the router, though this isn’t always straightforward. Once you locate the network settings, you should see details such as start address, end address, DNS information, and lease time. If you find a checkbox labeled DHCP or DHCP enabled, that’s likely what you need.

Thank you for your help. I accessed the router and saw the configuration for the port linked to my network switch. It mentioned manual setup addresses. I switched it to DHCP, but now I can’t reach the internet or even connect to the router. When I tried to manually enter my IP address, it kept showing no network. This happened before too. Ugh, this is really frustrating.

Hmm, verify the router's assigned IP address for your device. Is it part of the same network or subnet as the router's IP? If you turn on DHCP but it broadcasts a different network than the router is on, you'll lose connection. We can confirm this by assigning yourself a 3.X IP and checking if you can reach the router. If successful, adjust the router's IP to match the DHCP pool's range. You should also ensure the router's IP is set correctly—check networks 2.1, 1.1, and 0.1—to confirm DHCP is advertising 3.2 through 3.254 before enabling it. In short, DHCP changes can affect the router's address, so double-check those settings.

Don't configure DHCP from your router to the switch. Set it up on the modem-to-router port so the router assigns its own IP and uses NAT. Assign a static IP via NAT Manual IP on that port for the switch. Each network segment should have its own DHCP pool in the GUI. You may need to configure NAT separately if required. I don’t use Ubiquiti equipment.
