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), until I connect my phillips hue bridge via wired. After ~6 hours, the router disconnects all wired devices and refuses to assign them a new IP through DHCP (have also tried assigning these devices to static IPs to no avail). I've looked through the logs on the router during these events and all I can seem to find is a few failures to assign an entry to the ARP table around the same time (will post the exact entry when it happens again). Disconnecting the Hue completely from the network solves all of the problems. Looking for any advice. I'm savvy but not a professional network engineer. Will post any more info that could help!

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.
- Could you upgrade to this firmware and see if it resolves the issue please? https://forum.netduma.com/topic/28523-new-xr500-hotfix-firmware-for-drop-outs/
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.
- Keep us updated on how the firmware works out!

Then set the hub to static on either side of this pool.
Sounds like this router and the hub don't get along well.I did this (setting the hub to a static address outside the DHCP range), but am now seeing issues with wifi speed on various devices. At this point I think I need to involve phillips support.
Ya, seems like the hub doesn't like the XR router for some reason.
Curious, what was the last Mfr and model# router use with this hub if you had this configuration then?
