Just got this free modem from Telecom. 


The previous modem IP address is 10.1.1.1, subnet of 255.255.255.0, and the DHCP issued IP addresses from 10.1.1.20 to 10.1.1.253. 


So , plugged in the TG585, it started up ok and connected to the internet OK.




Now I would like up configure the TG585 IP/DHCP to be the same as my prior modem. As shipped, the default IP address for the TG585 is 192.168.1.254.




I've gone into the menus to try and change this, but it is confusing compared to my previous modems. 


I got to the "interface-local network" page....



IP Addresses
IP Address/Mask Type
10.0.0.138/24 Static Edit Delete
192.168.1.254/24 Static Edit Delete


DHCP Pools
DHCP Pool Name Address Range Gateway
LAN_private 192.168.1.64 - 192.168.1.253 192.168.1.254  


I don't get this. Why are there 2 IP addresses? I don't see the point of 10.0.0.138/24.   There is no apparent place to change the 'gateway' ip address either.
  
Does anyone know the steps to change the default IP address/dhcp allocation range for this router? Telecom provides no useful documentation with the modem.
