Hey everyone, I recently upgraded my setup with a faster line and wanted to make some changes too. My main modem is an Arris TG862—it doesn’t have QoS and mainly serves as a switch and DHCP server. The second device is an Asus RT-N12+, which works as a wireless router plus a QoS client for the connected devices. It’s linked directly from the Arris LAN port to the Asus WAN port. The Asus also supports DHCP, but assigns addresses on its second subnet. Downstairs, I have a TP-Link TL-WR940N that behaves similarly to the Asus and connects straight to the Arris via the WAN port. It also has DHCP enabled, though it uses a third subnet for assignments.
I’ve noticed online discussions suggesting DHCP should be set up on just one router. I’ve tried this mostly with the Asus and had issues. Turning off the Asus’s DHCP made the router unusable—I had to reset it to access settings again. Changing the IP to match the Arris before switching off DHCP helped temporarily, but once I disabled it, the Asus settings showed the internet cable wasn’t connected (even though it was) and the QoS didn’t function properly. It recommended switching to AP mode, but that doesn’t support QoS.
What do you think? Is having three DHCP servers across different subnets really problematic? Any tips would be appreciated!
The only time you need to change the DHCP settings is when they’re all on the same subnet. That’s the case. The main problems could be with certain software that resists double NATing and port forwarding will be tricky. Otherwise, if everything functions, it should work fine.
A potential problem could be linking to the adjacent network.
Equipment from Router A cannot communicate with devices on Router B, and vice versa.
