Wireless Connectivity Issue with 802.11n.

We have a 5508 Controller and sixteen 1142 APs.

Several of our laptops were experiencing connectivity issues over Wireless.  Older laptops that do not support 11n are not having any problems.

I disabled 802.11n for both 'a' and 'b/g' in the Controller.  Now the newer laptops connect with no issues.

They would in fact connect to the APs while 11n was available, just no Internet Access - (cannot ping DG, etc).  Disabling/Enabling the laptop WL adapter would allow brief access (sometimes), but they'd quickly lose Internet Access once again.

Our WLANs are configured for WPA2/AES.

This looks like a 802.11n configuration issue at either the Controller or the Laptops (or both).  Both are using the Default settings for 801.11n.

Any recommendations for correcting this?  Are there best practice guidelines for configuring 802.11n?

Thanks.

- Jay
