Getting a Motorola SBG6580 into “Bridge” mode on TimeWarner Wideband
- Unplug coax cable from Motorola
- Hold down the white reset button on the back panel with a pen for 30s. This resets all settings to factory defaults. The modem will be auto-reconfigured once you plug in the coax cable.
- When modem is back on plug in a computer with an Ethernet cable into the modem.
- Connect to http://192.168.0.1 and login with “admin” / “motorola”
- Now you will make some changes:
- Wireless -> Primary Network -> Disabled
- Basic -> Setup -> NAPT Mode -> Disabled
- Basic -> DHCP -> No
- Advanced -> Options -> Rg Passthrough -> Enable
- Advanced -> Options -> Passthrough Mac Addresses -> Add WAN MAC address of your router 6. Connect port 1 on the Motorola modem to the WAN port of your router.
- Plug the coaxial cable back into the modem and power cycle it.

Basic > Setup > Primary Network Only Mode: Bridged
was all I had to change onSBG6580-8.9.0.0-GA-05-062-NOSH
.So, in full:
Afterwards you can reach the router configuration page at: http://192.168.100.1
Notes:
You may come across this page: http://arris.force.com/consumers/articles/General_FAQs/SBG6580-v8-5-x-Bridge-Mode-Setup
It actually suggests the opposite, changing Gateway Mode to Bridged. But when I tried that the router would just reset its configuration back.
I was using an Time Capsule. That needed to be power cycled, otherwise it would still warn about Double NAT.
