Confirm what MCS rate you are connecting at, signal strength, and noise. Is your Mac client really bonding (should have a channel number with + or -1)? Make sure all of your data rates are enabled for the A band as well. user-111-123-111-1:~ $ /System/Library/PrivateFrameworks/

David, Make sure that you have WMM enabled on the WLAN. This is under QoS on the WLAN configuration on cisco WLC/WCS. It needs to be on to enable 802.11n rates. Also, make sure wide-channel is enabled (40MHz). To confirm what the Mac thinks is going on, enable the display of the WLAN icon in

David, In your output, the channel reading does not indicate bonding (channel number followed by ,1 for above or ,-1 for below). Also, the SNR listed in this output is excellent, this client should have an MCS data rate of 14 or 15. Try changing the AP channel to anything but 161. I

William, I have no answers, but would encourage you to vigorously engage your local rep and ask for an ear in Apple's development. It took us a while, but feels like they are starting to get that their products are actually less than perfect on the WLAN. -Lee Lee H. Badman Wireless/Network

Have you considered defining another SSID for high-speed wireless communications? We use the Cisco 4404-100 Wireless LAN Controller solution with 5.1.151.0 code and it allows us to set a radio policy of 802.11a only (and apparently 5 ghz n based on our testing) on a WLAN. We have a
