Converting Hitron CGN2 Bridge Mode
Place the Hitron in BRIDGE mode and use your EnGenius ESR600H router and you should be good to go.
If you do not know how to place the Hitron in Bridge mode just call Rogers Tech support and they will be happy to place the Hitron in BRIDGE mode.
Or follow my instructions assuming your Hitron is the CGN2 model:
Under the Capability Setting area REMOVE
the check marks from the following 4 areas: [shown in the graphic above]
Residential Gateway Function
Then click the Apply button. The Hitron should reboot -- takes approximately 2 minutes then wait an additional 2 minutes THEN connect your EnGenius ESR600H Internet Port to any of the Hitron LAN ports and power up your EnGenius router.
You can read the Hitron CGN2 user Guide
--- see page 42 - 43 where I found the directions posted above.
