CAX30 AX2700 - DHCP not working properly after power outage

I had a power outage the other night and after the outage, I noticed that many of my DHCP devices will not reconnect because they cannot get an IP address.

 

I saw a similar post where someone mentioned changing their NTP settings which I tried and did not help.

 

I'm on FW v1.4.10.8

 

I have had this issue happen previously, and Netgear support had me factory reset the modem, which did not fix the issue. The only thing I was able to do to fix the issue previously was change my SSID, which I cannot keep doing every time I have a power outage.

 

Right now I have been able to get a few devices reconnected by setting their IP instead of using DHCP, but this is obviously not ideal either.

 

Is this a known issue with the firmware and is there any verified fix for it?

 

Thanks, let me know if I can provide any additional info.

    Realized the model was incorrect in the title.

    It is a Nighthawk AX2700

      Hi jpryde,

       

      Welcome to NETGEAR Community!

       

      Thank you for reaching out. We are sorry to hear about your experience with the product. Just to clarify, with the previous power outage, resetting the cable modem allows you to reconnect the wireless devices but this time, even after resetting the wireless devices won't reconnect, you need to manually set the IP address to each wireless device in order to reconnect, is that correct? Also, does it affect both wired and wireless devices or only wireless devices? Have you tried to reflash the firmware already?

       

      Please do not hesitate to let me know if you need further assistance. 

       

      Regards,

        Hi,

         

        Doing a full factory reset "fixed" the issue, however if I changed my SSID back to what it was before I did the factory reset, the issue returned immediately. It was only after changing my SSID that it went away.

         

        This time, I imagine if I changed my SSID again it would fix the issue, however I can't keep changing my SSID every time I have a power outage as I'll have to reconnect every device in my house every time it happens.

         

        I have reflashed the firmware and it hasn't solved the issue, I'm on the latest firmware currently.
