Re: 7921 Connection Failed

No, this is configured on an autonomous AP, but is really only mandatory if you have a -W model phone, which requires that 802.11d / world mode is enabled on the AP.

For losing connection, maybe could be BSS loss due to missing beacons or ACKs.

Would try 1.0.4 image, which is the latest.

Hi Victor

The command should be entered in the IP Phone 7921, using the USB connection?

And if I'm getting this error of authentication at a LWAP with WLC 4402. How can I do? There is a command like that to insert at WLC??

Re: 7921 Connection Failed

World mode (802.11d) is automatically enabled with the Cisco WLAN controller. When you choose the country (Wireless>Country) for which your APs have to match, then this also sets the country code for 802.11d.

Re: 7921 Connection Failed

To factory reset your 7921 ip phone, go to Settings>phone settings then press **2, it will display "start factory reset now" select yes and you are done.

Hope that helps.
