The configuration changes that will resolve the issue are to configure set vaps to be “Authors” for both interfaces in the wtp-profile, and to configure vap-all to be manual for both interfaces in the wtp-profile. This is because the current configuration does not assign any VAPs to the AP interfaces, which means that no wireless networks are broadcasted by the APs. The vap-all setting determines whether all VAPs are assigned to an interface or not, and the vaps setting specifies which VAPs are assigned to an interface. By setting vap-all to manual and vaps to “Authors”, the APs will only broadcast the Authors wireless network on both interfaces. Disabling intra-vap-privacy for the Authors vap-wireless network will not help, as it only affects the communication between clients on the same SSID, not their connection to the AP. Increasing the transmission power of the AP radio interfaces will not help, as it only affects the signal strength and coverage of the APs, not their broadcasting of wireless networks.
