DHCP Issue

[rollerrrr]

My network setup includes a C7000 Modem Router and an EX8000 WiFi Extender. I found that devices that connect to the WiFi extender may be given the same IP address sometimes. My current solution for this is assign static IP addresses for most of my devices. But there are some devices which cannot be assigned to static IP addresses, for instance, my HomePods. Even if I only have two devices using DHCP function, this IP conflicts still happen sometimes, which is very annoying.

THe Modem Router and WIFi extenders are running the latest version of firmwares. And I don't enable the One WIFI name function so they have different SSIDs. 

I wonder if anyone has a solution for this? Thanks!

I have exactly the same problem with an EX7300 running the latest firmware.  I found that shortening the DHCP lease time helped some devices.  There is definitely a problem with the DHCP snooping/intercept/reply on the EX7300.  My laptops work fine now, my iphones are stubborn and I finally gave up and assigned IP addresses.

Same issues with Extender 6420 and Router RAX200 (DHCP Server).

The extender is connected to an unmanaged HP Switch, using fast lane capability (5GHz ONLY). 2.4 radio is disabled.
