Rogers Hitron modem Bridge mode (model# CODA-5810)

This is how you can use your own modem for routing vs your cable modem. 
You do it this way below to avoid double NAT'ing (which can cause problems with programs, saves on unnecessary processing of your internet connection, so faster).

1.  Logon to your modem with your user/password
2. On menu at the top, click on "BASIC"
   
   
3. Select "GATEWAY FUNCTION"
   
   
4. Then on "Residential Gateway Function" select "DISABLED"
   
   
5. When you select DISABLED you'll be prompted with this warning.  Select "OK
   
   
   
   
6. Select SAVE CHANGES
   Your modem will now reboot
   
   
7. Connect a cable from the LAN port of your Hitron modem to the WAN port of your personal router
   
   
8. Once the modem reboots, the WAN Ip of your cable modem provider will now be on your personal router, assuming it's automatically assigned. 
   If you were provided some WAN hardcoded IP information by you provider, put that into your personal router.
   
   
   
9. The cable modem itself will change its management IP to 192.168.100.1
   
   
10. In most cases, you should be able to access that without any other changes if you want to set it back.
