Using AirPort Express to extend Cisco E1200 router.
I have an AirPort Express that I am attempting to use as a wireless extender for a Cisco E1200 router and am having issues. The person I am helping is using their iPad as the wireless device, but needs the extender to boost the signal for the rest of the house. I was able to get the AirPort configured to where I have the green light. But when the AirPort Utility is opened on the iPad, it does not see the Express. The Express is connected to the Cisco router via Cat5 and the Cisco is going to the modem. I believe that I need to setup the Cisco as my base station. Does this mean that the AirPort utility needs to be installed on the PC that the Cisco is running on? Any help would be great.
