I got it to work by disabling NAPT mode and thus the modem restarting. You are then good to go:) Of course, you'll still want to disable the Motorola wifi if your own router has it already. Don't plug anything into the Motorola except the WAN port which should connect to your router. Set your DNS and configuration settings on your router device and plug all PCs into your own router. Ensure your own router device is in another range like 192.168.1.0/24, usually by default. Let it grab a default DHCP address of 192.168.0.2 and offer route via 192.168.0.1. Plug your own device's WAN port into the Motorola port #1. Or you could just use the 'double-DHCP' trick.

Plug the coaxial cable back into the modem and power cycle it.

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.

Advanced -> Options -> Rg Passthrough -> Enable.

Basic -> Setup -> NAPT Mode -> Disabled.

Wireless -> Primary Network -> Disabled.

Connect to and login with “admin” / “motorola”.

Is it possible to use as a bridge just with wifi connection? Not using the. When modem is back on plug in a computer with an Ethernet cable into the modem.Ĭonnect port 1 on the Motorola modem to the WAN port of your router.The modem will be auto-reconfigured once you plug in the coax cable. This resets all settings to factory defaults. Hold down the white reset button on the back panel with a pen for 30s.Found at: Getting a Motorola SBG6580 into “Bridge” mode on TimeWarner Wideband
