I am running 5 1252 AP's as "hotspots". I am using both the 5GHz and 2.4GHz radios. I am using a power injector to power the units. I am using 3 antennas on both radios and I'm using diversity mode. I can can see the A,B,and G signals, but no matter what I do I can not see the N signal. I am using channels 1,6,or 11 on all 5 AP's. Any suggestions would be appreciated.

What's your encryption? For 11n to work, you need either OPEN or WPA2 AES.

"The 802.11n HT rates apply only to no encryption or WPA2/AES encryption. They do not apply to WEP or WPA encryption. If WEP or TKIP encryption is used, 1140 and 1250 series access points and any 802.11n Draft 2.0 clients will not transmit at the HT rates. Legacy rates (802.11a/b/g) will be used for any clients using WEP or TKIP encryption."

Hope this helps.

Just so we're all clear: from the Cisco documentation:

Note The 802.11n high-throughput rates are available only on 1140 and 1250 series access points for WLANs

using WMM with no Layer 2 encryption or with WPA2/AES encryption enabled.

Can you post your config (sanitized of passwords and IP addresses)?

Thanks for all of the help. The issue was w/ the WPA2 encryption, or the lack there of.
