Abstract: Various aspects of the disclosure relate to determining whether a signal detection function is properly detecting for a signal. In an example implementation, the signal detection function detects radar signals. If the signal detection function is not functioning as desired, communication on at least one wireless communication channel may be disabled.

Abstract: A direct connection mechanism can be implemented for legacy wireless network devices to securely connect to a WPS-enabled access point. A legacy wireless network device can connect to the WPS-enabled access point and can provide a PIN of the WPS-enabled access point and a predefined keyword that indicates that the wireless network device is not a WPS-enabled wireless network device. In response to determining that the wireless network device is not a WPS-enabled wireless network device, the WPS-enabled access point can switch from a WPS authentication mechanism to a legacy authentication mechanism compliant with legacy wireless network devices. Such a direct connection mechanism enables legacy wireless network devices to connect to the WPS-enabled access point using the same connection model as would a WPS-enabled wireless network device (without a user having to manually configure underlying protocols and without changing implementation of the legacy wireless network device).
