In this case. the dashboard interface lists wired wireless mac addresses. The wireless one is apparently not used. They probably should list the wired mac address in both places.

All, The AR5007 chipset appears to be b/g only, not 5 GHz. Not using DHCP proxy. Tried ClientLink on and off. Tried CleanAir on and off. No difference. -Mike -Original Message- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:wireless-...@listserv.educause.edu] On Behalf Of Lee H Badman Sent: Sunday, August 22, 2010 7:28 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] Cisco 3500 APs and Atheros AR5007 chips Another question- are you using DHCP proxy in the controllers? -Lee Badman From: The EDUCAUSE Wireless Issues Constituent Group Listserv [wireless-...@listserv.educause.edu] On Behalf Of Jeffrey Sessler [j...@scrippscollege.edu] Sent: Sunday, August 22, 2010 7:47 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] Cisco 3500 APs and Atheros AR5007 chips Mike, Is this to both 802.11b and 802.11a?

RE: XBox 360 S
Wow, that part is definitely new. Thanks for the heads up! A whole ton of consoles showed up this weekend, so I bet a good number of people registered the wrong MAC address.

Any issues with iPhone 4 and 2.4GHz 802.11n?
Folks, I was talking to a higher education IT guy last week; they have a lot of iPhones, and are rollling out iPhone 4's to new freshman and to faculty. As part of this, they upgraded the campus WLAN to 802.11n. BUT, after iPhone 4 was announced, they realized its 11n support was ONLY for the 2.4 GHz band (with of course only 3 non-overlapping channels, and tradeoffs if you merge two of them into one 40MHz channel). In SOME locations, they're having to do some fancy juggling of access points, channel and power settings. Juggling 3 channels in a crowded location clearly is NOT new. But the fact that this is occurring in 11n with a popular client device that often relies on WLAN access, seems noteworthy. I was wondering if anyone else is running into similar issues with iPhone 4 and 11n? I'm going to be writing this up as a Network World story today or early Tuesday. If you're interested in emailing/talking briefly with me about this, please just copy any listserv response to (or email me directly at) my NW email: john_...@nww.commailto:john_...@nww.com. Thanks!

Re: [WIRELESS-LAN] Any issues with iPhone 4 and 2.4GHz 802.11n?
John, I don't think there is much of an issue here, unless there is a requirement that the iPhone 4's need the bandwidth possible using 40Mhz channels. Just about every design guideline I've seen, and every conversation I've had with engineers at various networking companies, considers using 40Mhz channels at 2.4Ghz to be a bad idea, due to the loss of what little flexibility one has with channel layout as well as with adverse effects on neighboring networks in crowded areas (the anti-social effect), so here at least we never considered it. -Chris On Aug 23, 2010, at 9:12 AM, j...@nww.commailto:j...@nww.com j...@nww.commailto:j...@nww.com wrote: Folks, I was talking to a higher education IT guy last week; they have a lot of iPhones, and are rollling out iPhone 4's to new freshman and to faculty.
