Lee, My main point is that since you have written many times about Aruba's wireless offerings, I thought you would be more familiar with their features.
The know that a few years ago, at least, I talked with a Meru customer who said the system preferred that all APs on a controller be configured the same, so Cisco is not alone in this regard. I just took exception to the broad brush of painting *all* controller based systems with this deficiency.

Hi Bruce- Your confusion is justified. Though I was at the Aruba conference, I am a Cisco customer. I should have put a finer point on my lament- I wish ALL controller-based wireless systems allowed for per AP settings like data rate variances. :) Lee Lee H.

OK, Lee now you have me confused. I have seen you at Aruba user conferences, so I thought you knew their product. I have heard Meru prefers a common setup for all APs on a controller (or at least they did), but I did not think you were using them. Our Aruba system lets us set data rates on an AP or AP group per SSID and the whole multi-controller system is managed from a central interface. Aruba has had these features since before we started evaluating them in late 2006. Even if you set the rated per AP group, you can customize individual APs apart from the group, This is useful if there they have only a couple of settings different from the group. I do not know how long running your beef has been, but that was solved years ago. Aruba also lets you steer clients to the 5GHz band to you can reserve the 2.4GHz band for b/g/n users. Of course, they also handle multicast video over Wi-Fi well too. Note: I am not an Aruba salesman. Just a happy customer.

One of my long running beefs with controller based systems is that data rates settings are per controller. Would be nice to be able to set the two APs I might need for scanners to 11b rates, while letting the other 498 do no less than 5.5. Perhaps I want too much... Sigh. This technology stuff... -Lee Badman ________________________________________ From: The EDUCAUSE Wireless Issues Constituent Group Listserv [WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Osborne, Bruce W [bosbo...@liberty.edu] Sent: Tuesday, May 31, 2011 7:37 AM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] Dual radio APs, .11n on 2.4ghz radios or not? In our 2.4 network here at Liberty, this is what we setup that works, at least for Aruba APs. Transmit Rates: Only 5.5 & higher Basic Rates: 2 & 5.5 I believe some gaming systems needed to see 2 Mbps as a basic rate, but it did not need to be transmitted.

We're also running into similar issues with purpose-built PDAs, of the type used to scan tickets and inventory etc. Also, I seem to recall that Nintendo DS will not associate if it doesn't see the 1 Mbps rates. How other universities are dealing with discontinuing support to existing devices would be interesting to hear - or if there's a technical solution someone has devised for this.

Rick, What are you doing for Wii users? The last time I checked they required the lowest G speeds in order to associate. Please tell me they fixed it with a new code release for the Wii's.. http://www.networkworld.com/community/blog/dropping-legacy-80211-support-your-infrastruc Jeremy From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Rick Brown Sent: Thursday, May 26, 2011 2:07 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] Dual radio APs, .11n on 2.4ghz radios or not? Craig, Enabling N on the 2.4 is not a lost cause and will help improve performance if the coverage has been designed properly. As of June 1st we are disabling 11B and all 11G rates below 12Mbps. In order to help steer people to the 5Ghz band we have created an SSID that is only broadcast in that band and publicized it as higher performance.
