What are the two devices that appear to be making DHCP requests so often?
DHCP servers do not spontaneously decide, "oh fun. Let's issue an IP to this device again (and again)." Some time ago, I documented a a situation where my Windows laptop would not have internet when it had gone to sleep when I closed the lid and then reopened it hours later The only way to get internet was to perform a restart. (that situation was cured with a Windows software update.)
I set up Wireshark to capture the Ethernet port and discovered that the laptop was sending out DHCP requests. The Orbi router was answering them correctly. But the laptop just send out another DHCP request.
I agree, DHCP servers should not, which is why this is strange.
The 4 devices that appeared most in the logs before i did address reservation, 3 were macbook pro's and 1 was apple watch. The strange thing is without making any changes to the laptops, the activity stopped after reservations, if the laptop was an issue we would still see a dhcp request.
What is the lease period of Orbi DHCP lease?
First time seeing this? - have seen this for a while, since i started looking at logs as part of the reboot problem
What brand and model# devices do you have connected? - Apple macbook pro, 2019, 2021, 2024
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too? - Motorola B12 (i had a SB6141 before which i thought caused the reboot problem so replaced with B12)
Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended. - Yes, but i doubt this is causing DHCP issues between Orbi and end devices
