After you change the router IP address to 192.168.1.1, your PC or laptop will temporarily loose connection with the router. As long as the PC/Lap are set for DHCP, you should be able to disconnect, then reconnect to the router. If you are wired, try unplugging the ethernet cable, then reconnecting. If you are wireless, try disconnecting the connection, then reconnect.
After you get connected again with your router, try typing the IP address of the Cube into your browser: 192.168.1.254:8000
Hopefully you can configure the cube with a new IP address (ideally use the other Cube's IP address plus one, 192.168.10.201 if your other cube is 192.168.19.200, for example). Also set your pool address, port #, username, pass, etc.
After all of the cube setting are correct, go back into your router setup page (it has changed to the new IP address that you temporarily set, 192.168.1.1). Now change the router IP address back to the old 192.168.10.1. Reconnect your PC/laptop to the router and then you should see the second cube on the network.
It won't let me change the IP.
I get the following error.
Access Error: Data follows
IP address is identical to WAN
Plus when I change the IP the gateway changes as well. Then I click apply, and that is when I get the error.
One thing that I noticed is not to be too hasty when your browser says it can't find that address you are using. Somehow I noticed that if I tried to connect a second or third time WITHOUT making any changes, it would connect.
What was happening is that I would instantly change something, and it wouldn't connect then either. I just happened to notice that this happened. Thank Jeebus.
