I'm setting up an office network consisting of: - ATT ADSL2 Modem -> CISCO Router (198.x.x.x) -> Airport Extreme
I'm having an issue getting the Airport Extreme (6th Gen) to connect to the network. I want to use the AE to serve its own 5Ghz and 2.5Ghz network. The issue isn't configuring the wireless details - it is how to get the airport to connect to the router correctly.
Upon connecting the AE as a fresh factory default device, it reports:
What is the correct method to setting up the Airport Extreme in this instance? I've tried the roaming setup on Apple with no success.
