    Ok, I'm stumped on this one. I've been up and down the web but can't find a definitive answer to this question. Is a wireless access point a layer 1 or layer 2 device in the OSI reference model? I've seen sites that go either way. It seems like it would layer 2 in terms of access control but of course, radio waves as a medium would be layer 1. If a WAP is as simple as a hub, then it would really be layer 1. I'm confused. Does anyone know the definate answer including references to support it? Thanks. :oops:

    I think I found the answer but it's not very straight forward. Apparently, at the antenna end of the AP, the device is layer 1 since radio waves are part of the electromagnetic scale. At the Ethernet end, because the AP processes information (rather than just passing it through like a hub) such as WEP, MAC address filtering, and SSID broadcasts, it functions as a layer 2 device.
