Modem only power light blinking
My wifi went down today. I can still connect to it but cannot get on the Internet. I checked the modem and found only power light blinking dimly while others completely off, and router's light is red. I tried to reboot all the devices including ONT and router but it didn't work. I wonder if the modem is broken but it's been no more than 2 days since a staff set up the broadband for me. Could anyone help me solve the issue?
