Netgear C7000-100NAS relentless T3 Time-outs and rebooting
About 2 months ago, my Netgear C7000-100NAS started having at least 5 reboots a day (sometimes up to a dozen times a day!!). Error logs read T3 timeouts relentlessly. Firmware Version V1.01.28
There are no splitters, I'm running directly to the wall. I had Comcast techs come out and they said everything looks good, strong signals, etc., and suggested it might be the modem/router having troubles. So I'm stuck between an ISP and a modem manufacturer. Can someone PLEASE help, I work from home and rely on a consistent connection, and am not getting it.
Here is the most recent log (after recently be cleared FYI, but just imagine T3 error logs 5-12 times a day😞

Re: Netgear C7000-100NAS relentless T3 Time-outs and rebooting
right where you found "event logs" .. there would be another option on left hand column for "logs" and they will have all the network logs showing if Internet disconnected or not.
