Hi Bruce, We didn't have a formal test plan, but have had many experiences I am more than willing to share. Surveying was pretty interesting, as we deployed before there were any 11n capable tools available. Back in the summer of 2007, we pretty much just had to make some assumptions and then

Hector, I believe this is what I have observed as well. Sometimes you have to open the network icon in the systray to get the credential box to appear. I see this when I log on locally as an Administrator rather than a domain user. While we're talking about PEAP, does anyone know whether

Thank you Matt, I appreciate the feedback and may want to get more of your Meru experiences offline. A 5GHz RSSI (PHY) survey seems to be the common denominator for legacy and .11n clients. Its likely this provides adequate coverage for 2.4GHz clients. In fact it may be overkill for 2.4GHz,

I had an interesting exchange with Ekahau (we use them and AirMagnet) about how 11n should change surveys, cell representations, etc. I don't want to speak for them, but beyond data rates, overall survey representations really won't change much. There are nuances to this of course, but to try to

I had to check the configuration guide, but the 5 GHz maximum power levels for the radios are documented as follows for the US: Channel 36-48: 23 dBm Channel 52-140: 30 dBm Channel 149-165: 36 dBm Matt Barber Network Analyst Morrisville State College 315-684-6053 -Original Message-

Yeah, that is something I should have mentioned. The coverage maps look extremely interesting with MIMO playing a factor. If you have seen any 11n data rate maps with the strange pockets of coverage showing up as you move away from the APs, that was what we were seeing in real testing. Rather

Now that would be interesting - different data rates and/or Radio Management support, per controller, based on an AP Grouping mechanism. The fatter these controllers get the more it has to be the procrustean bed for all sorts of wireless devices. Does any Thin AP vendor support this? Bruce T.

If I understand you question, I feel it is addressed with the MERU system. They use TDM instead. Each need is handled via a time slice. Multiple needs, A, B/G, WPA, WPA2, WEP, etc etc will have its own time slice. Did I understand you question wrong? Thanks, Christopher DeSmit University of

Thanks Chris, Meru is a different beast somewhat, as it uses a more of a point coordination mechanism (TDM-like as you indicated), rather than the DCF function (everything's a station - STA - whether it be a client or an AP) of other 802.11 products. This is something akin to the Token Ring

Hector, I've had that functionality working since SP2. Are you sure that your RADIUS server hasn't changed since the last time you tested this? On Thu, Jan 29, 2009 at 9:46 AM, Hector J Rios hr...@lsu.edu wrote: I don't know if anybody has brought up this issue before, but for those of you
