Now we are going to look at putting the new Time Warner high speed internet modem router combo into bridge mode so that you can use your own network equipment with it.
The Time Warner technician who connected my service did not understand what bridge mode was. After some discussion and explanation, he disabled the wifi transmitter but did nothing else.
This left my dd-wrt router being assigned a local ip address... which is useless to me.
Here we go...
- 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.
- 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.
- Power cycle your dd-wrt router.
- Check to see that the external ip has now been applied to your dd-wrt router.
Your SBG6580 should now be in bridge mode.
Your dd-wrt router is now given an external ip.
