C6300V2 MODEM WON'T AUTO CONNECT TO INTERNET AFTER POWER FAILURE

I have had 2 power failures and each time the router restarts but the modem won't reconnect until I have disconnected then reconnected the cable to modem.  Never had this peoblem with any other router/modem.  first I was out of town and network down for 4 days til I got back.  router was working but no internet

C6300 v2 with latest firmware 1.03.06

  • I own the nighthawk modem/router so .... my latest troubleshooting reset the device, then restored my old settings.  device rebooted fine.  fortuitously a tstorm passed by and briefly lost power... may have fried the surge suppressor but the modem started back up

    So maybe i just needed a reset.  on the other hand, that leads to poor reliability if i am not at home to reset.

  • If possible call your ISP and have them run a test against your modem.

     

    Could be  power outage affected your modem.

    Do you use surge protectors on your modem and router?

      I use a power strip that claims to have protection.  All other gear is fine.  Does your modem auto reboot and reconnect to internet after disconnecting the power cable?

        Have tested again... cycle the power using the on/off switch... system reboots, wifi turns on, no internet connection.  Nighthawk says check rf connection.  wait awhile then use the nighthawk connection (192.168.0.1) to renew the ip connection and the internet is restored.   So if the power goes out I need to either reconnect the rf cable or reset the ip connection.  both are manual actions so I have to be home or it's out for days.  Is this normal?
