AC3200 router developed IP address conflict.

After power disruptions (storm) now noted in scan of connected devices that root IP addresss of half of devices is 10.100.1.1 and another IP address root for remaining devices is 192.168.1. Thirty devices total.
Internet gateway access is denied.
Any idea of problem or a fix? Is router fried from multiple power interruptions and surges?
Tried router reset along with power reset of modem as well as router to no avail.
Help please!

  • When a router is rebooted, all of the DHCP leases are invalidated.  Force your devices to renew their leases or simply reboot them. 

  • I removed all devices from the switch and one by one plugged back in switch for DHCP to assign a new address.
    No change in problem. Am I missing something?

      Are you talking about a standalone switch? Or are you referring to the switch in the router?

       

      Can you describe your setup?  Is it the following?

      Modem---Router---Devices

      Is the WAN port on the router connected to the Modem?

    Did you do everything in the right order?

     

    Here's what Netgear recommends:

     

    Be sure to restart your network in this sequence:

     

    • Turn off and unplug the modem.
    • Turn off the modem router and computers.
    • Plug in the modem and turn it on. Wait 2 minutes.
    • Turn on the modem router and wait 2 minutes.
    • Turn on the computers.

     

    In this way IP address get handed out by the right bit of the network.
