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!
