Unplug it.

Yes. D-LINK would be *STUPID* to try to market a router that is *NOT* compatible with *ALL* cable-modem (or DSL-modem) units.

ARRIS modem is a phone/hsi modem. What youll need to do is first turn power off on xbox then unplug the power supply from the back of the Arris modem and unscrew the coaxil/cable wire from the back of the modem for about a minute. Then plug in the power cord to the modem wait another half minute then screw in the coaxil/cable wire....wait for the lights to come back on make sure the online light is solid green not flashing and follow the ethernet cable (Looks like a thick telephone wire) and make sure you have that ethernet cable seated/snapped into the ethernet port on your xbox. Then turn the xbox on and do connection test. FINISHED..IF it's still not working make sure you have Internet service from your provider and if using a router bypass it at first see if you can get onto xbox live without the router. If you can with just connected directly to your arris modem without the router involved. If you do want to use wireless contact your router manufacture and or xbox support at 800-469-9269.

Most likely the router is not configured for dhcp or is not renewing to pull an address from your new provider. You will need to login to the router and check the WAN ip address settings. Choose dynamic ip address (it may be currently set for for static or another option based on your previous provider). Once you choose and save the settings, click to renew the WAN ip. If you were already set for DHCP and the address is correct, you may still have an issue with DNS,.. the DNS addresses may be incorrect or non existent. If you have doubts about DNS addresses,.. you may change them to 208.67.220.220 and 208.67.222.222 (opendns) and they will work with most providers (including comcast)
I hope this helps,.. if you need details,.. please leave a comment and I can supply more.

u need a router to share internet connection, not 2 modems, from the way your explaining it im going to assume you just bought the modem went home and plugged it up, Well.. thats not going to work , your modem needs to be registered with the network your trying to access(comcast)

Trying to understand the connections. It looks like the problem is FM-WR. Everything else works. Are you powering everything off when you move the router from one modem to the other?

Hi taldrich6 - You have this listed under Arris CM450. Is that what you have?
