How To Configure Your Motorola SBG6580 Router In Bridged Mode

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.

  1. Unplug coax cable from Motorola
  2. 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.
  3. When modem is back on plug in a computer with an Ethernet cable into the modem.
  4. Connect to http://192.168.0.1 and login with “admin” / “motorola”
  5. 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
  6. Save all settings and plug the coaxial cable back into the modem and power cycle it.

  1. What router did you use and how did you set it up? I am having the EXACT same problem and the motorola tech told me I could not do that :(

    I want to throw the stupid thing out the window and I legit need all the help I can get to make this stupid thing work.
