RE: Dual radio APs, .11n on 2.4ghz radios or not?

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

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. Badman Wireless/Network

We have yet to deploy 802.11n, but are starting to investigate, so please excuse the newbie question. Could someone quickly explain the need/logic to set minimum rates on the 2.4ghz radios to run 802.11n at that frequency level? I'm assuming it's to limit the downgrading of the 802.11n performance

Lee (and others), correct me if I'm wrong here: Assuming a wireless deployment engineered for density over coverage (lots of APs for clients to connect to), there should be few and far between cases where having all rates enabled would have an impact on your system. That is, very small chance of

All, (I checked the Archives and couldn't find anything on this) One of our desktop support guy is losing his mind on a problem with three iMacs that have a very erratic behavior on wireless only. -Those iMacs were purchased during the last month. -They can join Wireless -They can get a DHCP

We had an issue a couple years ago where Macs were grabbing the whole class c range when they received an IP via DHCP. I think the way Apple handles the stack is just wrong. Any chance you have a v6 conflict or a proxy setting? This isn't another of your April Fools' posts, is it!? :P
