Issue with IP Assignment after Brownout on my XR700

Hello All,

Hoping someone will be able to help me out.

I have been having an issue with my router for about the past year or so where when there is a brief interruption to the power (say less then 1 min) when the router boots up most of my deceives have trouble connection and getting an IP.

 

Looking at my Alexa's it commonly shows DHCP error.

 

I can normally resolve this by rebooting the router a half dozen times then everything will connect with out issue.

 

Just wondering if anyone has come across this and if there is a fix? Thankfully it is not super common but is highly annoying.

 

My Network lay out:

1 Router

1 Nighthawk Extender

15+ Smart home devices connected via 2.4Ghz + phones ect.

 

Happy  to provide logs if will help.

 

Kind regards,

 

David

  • Reboot the router from the interface when everything is setup and connected, this acts as a hard save and should get you back online when there is a power interruption next

    What modem/gateway is the router connected to? 

    We see that sometimes when the router boots up faster than the modem and doesn't pull an IP address from the modem for a while. 

    Usually it just takes powering them both off for a bit then the modem on for a couple minutes then powering the router on.

      Hi plemans,

      I have it connected to a Sagemcom Broadband Router (Provided by my ISP)  but I  have disabled all its Wifi as i am only using it a 4G backup for when the Fiber connection goes down and as a modem.

      Kind regards,

      David

        When it happens again, reboot the modem, wait 2 minutes then reboot the XR, wait 2 minutes and see if it connects right away. Some modems/routers are picky about the boot order
