Welcome to Cisco Support Community. We would love to have your feedback.
For an introduction to the new site, click here. And see here for current known issues.
We recently purchased a dozen 1142's which I added to our 4404 controller running version 220.127.116.11.
I can't connect with the 802.11n protocol to any WLAN configured with WPA2 Enterprise, WEP, or WPA Enterprise with a pre-shared key.
I successfully connected using the 802.11n protocol after creating a new WLAN with no Layer 2 or Layer 3 security.
What am I doing wrong?
You'll need either an Open SSID or one with WPA2/AES encryption. Check the following link for more...
Thanks for your help.
Looks like the 3000 clients that currently use WPA2/AES with a pre-shared key to access the Internet won't be able to take advantage of 802.11N technology.
