Change Country Code in Beacon Frames

You can change the country code in beacon frames of VigorAP and Vigor Wi-Fi router at Wireless LAN >> Advanced Setting. This could be a solution when you see Conflicting Country Codes message on you wireless NIC.

You may check the country code of your country from the Reference link. And note that for dual-band devices, the country code of 2.4GHz and 5GHz radio are independent.
