I'm trying to connect an Airport Express (2nd generation) to a Cisco DPC 3208 cable modem and can't get it to work. I have an iMac (2.66 core2duo). The iMac shows the "!" sign in the wifi icon. Thank you.
I am trying to connect an Airport Express to a Cisco DPC 3208 cable modem to no avail. My iMac sees the network along with my neighbors but I get the "!" after trying to log on. It worked fine when I had AT&T DSL but just switched to cable for higher speeds. Thanks for your help.
