Constant DHCP requests

OK, I’m not sure what happened, but I haven’t had it go crazy on me like it was. The only change I made on my end was changing the channel on the 5ghz frequency to a lower channel (the Rachio is connected to the 2.4ghz) which has a completely different SSID. I doubt this would affect the DHCP issues I was having, but it appears the Rachio is maintaining a solid DHCP lease for 12 hours (which is strange as I thought it would be 24 hours). At least it isn’t going nutty like it was…

Please keep an eye on it; if you have a 24 hour lease time, a 12 hour renewal (50% of lease time) is normal - this allows the DHCP server to be unavailable for a while without affecting operation of devices on the network. See http://www.tcpipguide.com/free/t_DHCPLeaseRenewalandRebindingProcesses-2.htm for more info.

I don’t think your reconfiguration of networks would have made any difference - the dnsmasq daemon likely wasn’t even rebooted when changing the channel of a wifi interface.

I thought maybe your team shot another firmware update over…whatever happened seemed to correct the issue as it was an everyday occurrence.

Thanks for the info/help and a huge thumbs up to Rachio as a company. Great products and support. Bravo! :clap: :clap: :clap:

I realize this thread is 5 years old but I’m having the exact same problem with my Rachio 3 that’s located 3,000 miles away in my other home.

My Rachio makes constant DHCP requests to my Netgear R7000 router. Otherwise, it is working as expected and I can access it from my iOS app or browser.

My router emails me its log daily. Every other attached device has a normal frequency of DHCP requests, but my Rachio shows constant DHCP requests ranging from every 10 seconds to every 15 minutes.

Remotely rebooting the router doesn’t change anything. I don’t see a way for me to try rebooting the Rachio remotely. Any advice would be greatly appreciated.

I know this is an old thread. But, I have the same issue. My orbi router emails me DCHP made requests and it’s constant from Rachio 3 controller.

Example snippet:

[DHCP IP: 192.168.1.82] to MAC address 00:9d:6b:bd:a1:18, Thursday, July 13, 2023 12:09:53
[DHCP IP: 192.168.1.82] to MAC address 00:9d:6b:bd:a1:18, Thursday, July 13, 2023 12:09:20
[DHCP IP: 192.168.1.82] to MAC address 00:9d:6b:bd:a1:18, Thursday, July 13, 2023 12:08:52
[DHCP IP: 192.168.1.82] to MAC address 00:9d:6b:bd:a1:18, Thursday, July 13, 2023 12:08:35
[DHCP IP: 192.168.1.82] to MAC address 00:9d:6b:bd:a1:18, Thursday, July 13, 2023 12:08:08

and so on…

I have tried resetting Wifi one the controller. But, keeps happing. I will try to restart router off hours. But, looks like other had they problem before. Was it ever resolved?

Rebooting my Orbi seemed to solve the issue.
