Recently my Time Warner provided Motorola SBG6580 router has been just sucking. Random disconnects and the inability to handle 2 Xbox’s on the same network have made me mad enough to figure out how to break in the router and make it into a modem to connect my real router up to it.
Below are the steps that I have found to get your SBG6580 router into bridged mode.
- 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 > Configuration section
- Save all settings and plug the coaxial cable back into the modem and power cycle it.
