AS of yesterday morning when i looked at the gateway, the lights for 2.4 and 5 GHz wre no longer lit.
When I logges into modem , th euptime was only a few hours so I guessing got a refresh during the night. Wireless & Ethernet are working fine. Curious if there was an update to cause these two indicators to go dark.
Have you first tried powercycling / re-starting the device ? No joy ? Try hard resetting the device to factory defaults by pressing and holding in the recessed reset button on the rear for 30 seconds. You will lose any customized settings.
