No internet connection in an unorthodox situation

Solution 1:

I'm guessing here as I'm not certain of your layout of the specs of your RTRs. I've had this before with 2 standard home retail SOHO routers.

By default from factory both routers are set to DHCP server mode. You can only ever have one DHCP server on your network. If you have 2 DHCP servers on the network they conflict with each other and fight to setup ip connections, you have to disable one.

I'm not sure of details of your RTR specs but for me a rough overview of my fix was to have one RTR acting as:

• internet gateway, set NAT to on, acts as a RTR
• DHCP server on.

The other RTR attached to it set to something along the lines of:

• BRIDGE MODE acting like a switch
• DHCP server off or in DHCP relay mode.

This is a rough idea, your RTR should have some similar features, but the key takeaway here is only one RTR/DHCP server on, is ever allowed on your network to allow your devices to connect with an ip.

NOTE: also if you can't get to your transmitted router because it is stuck in DHCP server mode and conflicting with your other RTR you need to disconnect it from your other router so it's isolated to it's own network. Then connect in directly via LAN cable of wifi to it's web admin 192.168.0.1 admin:pwd or such to make changes before connecting it up to your other RTR.
