My old 3com cable modem died and i go a new Ambit modem from Time Warner today. But it doesn't seem to want to talk to my Linksys router or to the Netgeat wireles access point that is connected to the router. I've gone back to factory default settings on both the WAP and the router and power cycled them all in the proper order. All the connections are the same, the only new thing is the router. Any suggestions?
