Only Power LED light on SBG7600AC2 How do I fix my SBG7600AC2 WiFi cable modem? The power indicator light is on, but no other status lights turn on. No send/receive light, online light, wireless lights, or WPS light. My WiFi network is not being broadcast or not discoverable when I try to connect my devices. I have unplugged the power cable for 15 seconds, and power cycled the modem, but it still does nothing except show a power light. I also checked that the coaxial cable is tight against the back of the modem and tight against the cable outlet on the wall.
