The older Airespace APs had a site survey mode which was handy for just that. With IOS for the 1142 not being released yet, I was pondering a workaround
I was thinking of configuring an 1142 for HREAP - Authentication Local / switch local and then disconnect it from the network. I am unsure if the AP would bring the radio up if the Ethernet interface was disconnected? Can anyone comment on this?
