Cisco C3702i Universal AP unable to prime tried in autonomius and lightweight mode but failed to activate 802.11ac or 5GHz band or increase power of 2.4GHz band.
The issue is the country regulation enforce by cisco. It is in unprimed mode having a minimum 2.4G power . But failed to prime as it requires a CCO with service subscription from Cisco. Able too connect to vWLC it shows domain as -UX and unprimed. The Cisco AirProvision 1.74 apk is available but needs older Android to word and CCO account with service is mandatory.
Similar WiFi reg domain found in Raspberry Pi unable to activate higher WiFi bands in 5GHz band.
My Airtel broadband modem is supporting and working in 157 channel but Raspberry pi 4 is not supporting it . it says disabled. The issue is firmware cypress or broadcom . tried replacing it with the available firmware in the Internet but failed to activate these bands.
