Philips Hue hub break DHCP address assignment over LAN on NightHawk Router

Recently upgraded from a Nighthawk R7500v2 to an XR500 but the issue is the same on both routers. The router works fine with wired and wireless devices (I have a switch and xbox connected via wired),...

What is the Mfr and model# of the ethernet switch if one is in the configuration.

Can you set a IP address reservation for the HUE bridge? 

Or Try setting a static IP address on the HUE bridge if possible thats outside the routers default IP address pool. You may need to change the routers IP address pool from 192.168.1.2 - .254 to 192.168.1.100 thru .200. This will give you room on either side of the pool for static IP addressed devices.

    There is no ethernet switch in the config. The HUE hub directly connects to the router via eithernet. I configured a smaller DHCP range and set the HUE to a static address outside that. I saw no issues for a few days but last night the same issue again where wired devices were dropped from the network at the same time, and then could not receive a new IP via DHCP until rebooting the router. Will try updating the firmware with the hotfix mentioned in the other comment and see how that goes. 

    Thanks for all help so far.

      Please do a full factory reset and setup from scratch after updating FW.

        As recommended did a full factory reset of the router after updating firmware with the hotfix. Also factory reset the Hue hub module. Didn't set the Hue outside the DHCP range at first, and the issue came up again. The issue is interesting as it works in the following flow: 

        1. turn on router with all devices connected (including hue and other wired/wireless devices)

        2. a few days in wired devices disconnect and cannot receive new DHCP address (even if they are statically assigned an IP, still can't get IP from router)

        3. disconnect hue, issue persists

        4. reset wired devices (nintendo switch, xbox one), issue persists

        5. reboot router, issue resolved immediately. can connect hue again and lights work properly

        -repeat from step 2

         

        I will once again place the hue at an address above the DHCP range, but I'm starting to think I need to replace the hue hub module entirely. clearly it's doing something to the router that can only be resolved by clearing the ram...
