Just got this AP, glanced through the guides, fired it up to walk through the setup pages. Seems pretty straight-forward, however, The radio for 802.11g doesn't seem to be working. The radio LED light comes on briefly than goes off - not much of a pattern. I've got a Vista Business laptop sitting right next to it - can't "see" it. Have reset it three times now - same result. I'm brand new to Cisco products - where should I start on troubleshooting?
