===WPS (Wi-Fi Protected Setup) is a Wi-Fi Protected Setup (

The organization is implementing a certification program focused on simplifying the security encryption settings of wireless networks. Traditionally, when a user creates a new wireless network, they must manually set the network name (SSID) and security key at the access point, and then verify the key on the client to prevent the "uninvited guest" from breaking in. Wi-Fi Protected Setup can help users automatically set the network name (SSID) and configure the highest level of WPA2 security key, wireless products with this function are often designed with a function key on the fuselage, called the WPS button, users only need to gently press the button or enter the PIN code, and then after two or three simple steps to complete the wireless encryption setup, and at the same time establish a secure connection between the client and the router.

It is important to note that simplifying network security configuration with WPS requires both access points and client devices to be WPS certified, and users can look for the Wi-Fi Protected Setup logo on the product packaging to ensure that the purchased product is WPS capable.

I'm also having this issue, flashing is useless.

I couldn't flash the phone, so I was so angry that I took the phone and slammed it on my lap a few times.

Therefore, this should be caused by hardware problems and poor desoldering contact of the WLAN module.

Visual inspection of the possibility of flashing the machine is more likely, if not, the general reboot is Oh But if you want to solve the problem completely, it is still recommended to flash the machine.
