How do I set a DIR 655 so that it will work with my Comcast router.

I've talked with Comcast, and they have said set their router/gateway device to act as a modem, including turning off the WiFi.  I connected my DIR 655 input to the Comcast gateway output port 1, but the DIR 655 wont go online.  I was told I need to set the 655 to bridged mode, but I do not know how to do this.

The reason I would like to set it up this way, the Comcast router/gateway has no QoS controls, (not really any controls), not even a MAC filter, so I would like to use it as a modem only.

• What Hardware version is your router? Look at sticker under router.

Internet Service Provider and Modem Configurations

• What ISP Modem Mfr. and model # do you have?
• Is ISP Modem/Service using Dynamic or Static WAN IP addressing?
• What ISP Modem service link speeds UP and Down do you have?
• Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values (http://forums.dlink.com/index.php?topic=53008.0)
• For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.
• If the ISP modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems: Link>Double NAT (http://www.practicallynetworked.com/networking/fixing_double_nat.htm) and How NAT Works (http://cognitiveanomalies.com/cisco-nat-how-nat-works/). To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged. If the modem can't be bridged then see if the modem has a DMZ option and input the IP address the router gets from the modem and put that into the modems DMZ. Also check the routers DHCP IP address maybe conflicting with the ISP modems IP address of 192.168.0.1. Check to see if this is the same on the ISP modem, and if modem can't be bridged, change the DIR router to 192.168.1.1 or .0.254.

This model router doesn't support actual bridge mode:
