Here is a response I received from Aruba Engineering:
Bruce,
I have heard this from some of my other customers as well. The basic issue
comes down to the physical properties of the 5GHz wave vs. the 2.4GHz. The
lower frequency (2.4) will be able to travel through air and walls and even
bend
Here is an explanation from Aruba Engineering:
Bruce,
Both the 125 and the 105 have 2 spatial streams.
The 2x2 vs 3x3 is the MIMO antenna configuration. #of transit antennas (Tx) by
the # of receive (Rx) antennas.
There is also a 3rd metric (the spatial stream) it is represented by 3x3x2 or
Hello,
As far as I know, in Canada we don`t have a domain for universities. Limiting
the mailing list to .edu domain would block all Canadian Universities from
contributing to those mailing list. Please take that into account if you change
the rule.

FWIW:
After upgrading to 5.0.2 from 5.0.0, things fall back to 2.4ghz much
better than they used to. I think we still need to do some tweeking to
get things working as well as we'd like.
Unfortunately, we don't have the kind of budget to just throw out more
APs to fix the problem, so that's
Are you creating the .mobileconfig profile under the iPhone Configuration
Utility (iPCU) on a Mac computer? I had the same issue with iOS 4 iPhones. I
noticed that using IPCU version 2.2 on a Mac and a Windows machine produced
different PEM encoded certificates in the profile (if you opened
Wow. Thanks, that totally did it!
...interesting how the PC version of a piece of Apple software works better
than the Mac version. Of note I had tried the Mac 3.0 IPCU version, so the
problem wasn't address in that upgrade.
I haven't confirmed it, but my guess is that might be some sort of
Glad it worked out. Also, the Windows config was backwards compatible with the
iPhones OS 3.x, but you may want to confirm this also on your end.

From: The
I'd like to suggest that band-steering isn't causing this problem, it's
just making it more apparent. Presumably, we all want 802.11n clients
on 5GHz because performance and capacity are greater in that band. The
use of band-steering suggests agreement on this point. In that case, it
seems fair
In some buildings- particularly precast concrete apartments- on our campus, the
loss on 5 GHz signal can be pronounced versus 2.4. Like to the point where 5 is
non-existent and 2.4 will support almost full data rate. But this effect varies
wildly across our other building types.
Here is one of
