Hi Victor

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

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.

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.

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.
