Wireless Range Extender causing loops in my network

I have been using an EX7000 to extend wireless from my Cisco 891 router in my garage to the rest of my house. It is extending my SSID for the house for both 5ghz and 2.5 Ghz.

 

Everything was working fine until all the sudden the network goes down and I am seeing the following log messages on my Cisco Router:

 

000157: *Nov  1 07:55:35.150 PDT: %IP-4-DUPADDR: Duplicate address 192.168.10.1 on Vlan10, sourced by 020f.b590.1af4

 

192.168.10.1 is the IP address of the default gateway of my router. Nothing on my network was reachable and this indicates that there was a loop somewhere in the network. I powered down the extender and connectivity returned back to normal.

 

I did a hard reset on the extender and reconfigured it and it appeared to have the same issue. No issues with the actual SSID.

 

Not sure if anyone else has seem a similar issue.

    This might be one of the suspicious problems with the known-cumbersome EX7000 v1.0.1.78 firmware update. any users had to revert to previous firmware, like v1.0.0.66.

      Thanks for the response. I did not update my firmware, it's currently V1.0.0.50_1.0.102. I reset my router's AP service module and that seemed to resolve the issue for some reason. Based on your inital feedback, I will hold off on updating my firmware.

        Up to v1.00.66 has not caused (m)any complaints or discussions in the community.
