Re: DHCP constantly renewing XR500

Koz1614 · ‎2022-08-29

Hi,

Does anyone know why I am constantly seeing the DHCP new event/new lease? This happens multiple times per hour, everyday. I recently upgraded to firmware V2.3.2.134 which seemed to mostly resolve a disconnect issue I was having, but today I dropped off twice. Any thoughts?

How many devices approximately do you have on the network?

To help with the disconnections, you could go to Settings -> Setup -> LAN Setup and set the minimum DHCP value to be 100.

Then, reserve IP addresses for each device on the network. Give them IPs out of the DHCP range, between .2 and .99.

After that, see if the issue continues.

Hi,

I have about 10 - 15 devices at any given time. Is it normal to see the renewed lease like this all the time?

Heres the latest logs. Connection dropped off at 8:55pm EST tonight. Since upgrading to firmware .134 the connection seems more stable, but I thought I recall reading something about prior versions with DHCP lease issue?

They do seem a little more frequent than we'd expect, I'd suggest following the steps in my last post and see if the disconnections stop after that.

Koz1614 · ‎2022-08-31

Do you know what actually triggers these frequent events? I will try your suggestion

Netduma-Liam · ‎2022-08-31

In theory, it's a genuine DHCP lease renewal. By default the lease time is (I believe) 12 hours, which means it'll re-negotiate a new lease every 6 hours.

Koz1614 · ‎2022-08-31

Is there still some issue with this in the latest V2.3.2.134 firmware? I know I was reading about this issue with prior releases

Netduma-Liam · ‎2022-08-31

In this firmware, the issue is drastically reduced. We've still heard some reports from users having issues with disconnections, though it's hard to tell if it's the same issue. We're working on this still so if you are still experiencing issues, rest assured it's going to improve further for the next firmware.
