As far as I can tell, this is by design and happens with the older Xbox 360 as well. Students have to register those devices here, so I always have them get the MAC address from the Dashboard interface, because the one printed on the wireless adapter is not used.
Matt Barber Network and Systems Manager Morrisville State College 315-684-6053 From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:wireless-...@listserv.educause.edu] On Behalf Of Osborne, Bruce W. (NS) Sent: Sunday, August 22, 2010 11:05 AM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: [WIRELESS-LAN] XBox 360 S We have tested the new Xbox 360's and they are connecting to wireless with the mac address of the wired. Originally this was a cause for concern as if users were connected to wireless and wired at the same time there was a potential for a problem. After further investigation the Xbox360's turn off wireless if a wired connection is available even if it does not get an IP address from the wired connection. Hopefully this is not a bug in the new Xboxes and it is what Microsoft intended. The wireless mac address belongs to Hon Hai Precision, but the wired mac address belongs to Microsoft. This issue can affect any system that registers or filters based on mac address.
