Hello - I have a Motorola dsl modem that I got from AT&T. I have a Time Capsule that I am hooking the modem up to, so that I can have a wireless network and backup. I understand that I need to set the modem to bridging mode (or so AT&T tells me) but when I do so I don't have any idea what settings to use for the TC when setting it up in Airport Utilities. I need some help since AT&T wants $50 to help me with my "third party equipment." Thanks.
