    I purchased a WCG200 used from eBay. I connected it to my Comcast account and cannot get a WAN IP. Comcast can see it, & reset it. I have hard reset it MANY MANY times. I've contacted Linksys and hard reset it for them, verified it has no firmware to attempt that approach. It gets all the other information from Comcast. I have turned off all firewalls. I have connected it to 4 different PCs. It just WILL NOT get a WAN IP. Comcast doesn't want to work with me because I didn't purchase it through them, but I've talked with several techs who have attempted to help me out with the problem. The work with me for about an hour and then tell me they'll have to get back with me. A day goes by and nothing. Does anyone have any suggestions on how to get this thing working????? I'm about to pull my hair out! And if I am told to hard reset the thing one more time, the little button may get pushed all the way through the thing!

    Ok... frustration set aside here.... help needed!

    Update to Comcast Issue

    Ok... still at work on this issue here.

    I've discovered that if I connect my wrt54gs router to my rca comcast modem I have to clone my pc mac address in order for the router to work. If I connect my pc directly to the rca modem, I can connect. BUT... only my pc will connect. No other pc in the house will connect. I call comcast and they say they mac address provisioned is the mac address for their modem and for the new gateway. So, now I'm trying to find out how to clone my pc mac address to the wcg200 gateway to see if this will get me through to comcast. ANY SUGGESTIONS OUT THERE????

    If you had Comcast "provision" it....and you've power cycled should be good to go. You don't need to bother with MAC cloning. Once you read Comcast tech support your modems MAC..and they push the config file up to it to "provision" power cycle it..and you're good to go.

    If it's not getting a WAN IP...perhaps it's a bum unit. If your RCA modem is working...we'll assume your lines are OK.

    Well, that sounds like it'd be accurate. But, if I put the MAC address for the new unit into the working unit, it will not connect. I have cloned the working modem with the non working modems MAC address and Comcast assures me it's been provisioned. But it WILL NOT connect. So I'm trying to put the working MAC address on the non working unit to see if it will work. Does anyone know how to change the MAC address on the WCG200???

    I have the same problem with a WAG200G here in Norway.
