I have 2 1142's and 2 1131's. The WCS put them at [100 (104)]n, 116, 149 and [(157) 161]n.
Spectrum Expert and Channelizer 4 both see all four AP's chirping away.
Windows XP, using an Aironet 802.11a/b/g adapter on driver 18.104.22.1685 or
Windows 7, using a Cisco (Linksys) AE1000
see the two AP's in the UNii middle band (100/116).
Using WirelessMon 4 or inSSIDer 2 only the UNii Upper devices at 149/161 are present.
My 7921 phone has no problems linking to the AP on 116.
I find no device driver or other windows constructs to block the Unii Mid channels.
Your talking about the uni-2 extended channels. Not many devices support those channels.

As far as I know, both the AE100 and the CB21 should support Unii-2e. However, more to Scott's point, most customers don't have 100% client support for Unii-2e and therefore we often see it disabled.....
A Linksys AE1000 is like a Linksys USB600N, which is a perfect Wireless sniffer for all channels. I'm 99.9% certain it supports Unii-2e.Same goes for the CB21.
So I would honestly fully expect your clients to be able to associate to those channels.
Now of course as I write this, I can't get my cb21 using AnyConnect 3.x to associate to unii2e so I guess if I can get that working I'll let you know what I did.
Take a look at #5 on this link.

WOW! What a quick responce. I'll have to ask more dumb questions here.. but the only dumb question is the one never asked.
Thank you Scott and weterry..
Yes, my 2 AP's (over my head) are in the UNii-e (100-140) band now. The used to be in the UNii-L (34-48).
There might be a bit of MS in the pie. I use WZC on both my laptop (win7) and desktop (xp-3). Most of our WiFi utilities alse speak to WZC.. inSSIDer, WirelessMon etc. Netstumbler was an exception and IT doesn't function anymore.
I will check with Aironet Site survay and see what it says.
(In fact I just loaded it and it forced a reboot before I could save my first reply. This is ZAR2)
We upgraded the WCS from 7.0.119 to 7.0.172 so she must have switched channels then. Now I will have to check the other 150 units and do a reconfig.
On second thought, we are getting a LOT more phones a tablets.. This would force my laptops to stay on G..
Yeah… since there isn’t much supported devices on the unii-2 extended, it is best to remove them from the DCA list to be on the safe side. Devices that roam to AP’s on these channels will drop and cause you more headaches☺
You might want to consider disabling Unii2-e in DCA for the WLCs if you suspect you have 5Ghz clients that can't use it (which is most likely a true statement). Unii-1, Unii-2, Unii-3 still gives you like 12 channels which is basically 4x more than 2.4Ghz (even without unii-2e)
I loaded the Areonet Site Survay app and it does not see the UNii-2e channels either.
Turned off the UNii-2 extended channels in the WLC but I have to shut down the system to apply it.. Going to need to submit an RFC to do that.
We keep the desktops on G and leave A for 7921's and what not.
thank you all for the education..
Another gotch that burned me was on the newer WLC code channel UNII 3 (165) is an option. The Cisco 7925s dont support channel 165. This gave users the idea that there was a dead spot and there wasnt ... Just an fyi
