Why does the wps light flash on router?

The WPS (Wi-Fi Protected Setup) light on a router flashes when the WPS feature is activated and is searching for devices to connect. This typically occurs when a user presses the WPS button on the router to initiate a secure connection with a compatible device, such as a printer or smartphone. The flashing light indicates that the router is in pairing mode, waiting for a device to respond and establish a secure connection. If the light continues to flash without connecting, it may indicate a failed attempt or a device not in range.
