Hello, friend!
You need to log in to the web interface of the device to check the wireless network status of the device.
You can also restore the device to factory settings to check whether the fault is rectified.
Since the firmware of the device was upgraded yesterday, the current fault may be related to the later firmware version of the device.
After confirmation, the device version is customized for Saudi Arabia.
You are advised to contact the device provider or ISP to migrate the device firmware to the original version.
Thanks!
