Query: Junk not working with comcast broadband

I purchased this router thinking it would solve my wireless problem. Unfortunatly it has not. The router is working but I am not able to setup wireless. I spent hours with customer care and they were also not able to figure out what's going on eventhough they said that router is compitible with comcast broadband. I can user in wired form so it is junk for me.If you have comcast broadband then make sure before purchasing.
