Hi @ahmadnahas,   Welcome to the community!   What troubleshooting have you done so far? Have you tried to reboot the modem/router? If so please try to perform a hard-reset on the modem by pushing the small pinhole on the modem/router for 2-3 seconds, wait for the lights to flash then release it.   Modem auto configuration should take 3-5mins.   Let us know how it will go.   Cheers! ...
