Constant "DHCP old event" every 10 minutes

Recommended Posts

Hi, I'm currently running the R2 as a router attached to the modem, with an XR1000 serving as an AP on the other side of the house.
On the device manager panel it constantly goes online and offline, but devices are somewhat "fine".

Checking the logs, it looks like a constant spam of "DHCP old event" followed by a "DHCP lease change" is causing this.
I've been looking around the logs since a few of our devices have been disconnecting at odd times, and the logs on the XR1000 do show a disconnection at around the same time as what the household members reported a couple days ago, could this be related?

Either way, some devices are randomly disconnecting even when connected to the R2 and not the XR1000 so I'm not sure where to go from here.

I've given the XR1000 a reserved address via DHCP and apparently my laptop (which isn't even connected to LAN) has the exact same IP address and is showing up as being connected via LAN. Is the LAN behaviour expected from this setup, where it's connected via AP? I know for a fact the duplicate IP addresses isn't normal, and the laptop doesn't have a reserved IP address given to it either.

Thanks for any help :)

I've PM'd you, please try that and let me know your feedback

The XR1000 device is still being disconnected randomly, but there's no conflicting LAN IPs anymore as far as I can see.

It also shows that no devices are connected to WiFi, when there definitely are.

Is the XR still in AP mode? Does the log show anything different now when the XR disconnects? How long is it before the wireless devices reconnect?

Have you disabled the WiFi on the R1 and therefore all wireless devices connecting to the XR? If so that makes sense as it can't detect they're connected to WiFi properly as technically they're connected to the XR which is via ethernet so that's what it detects them as being also.

XR is still in AP mode, nothing has changed. Logs are the same on it too, disconnect/reconnect alongside NTP stuff exactly like how the logs were in the original post.

WiFi is also enabled on the R2, and even though my phone and laptop is connected via the XR, it still doesn't show that those devices are connected.

Interesting, as your XR upgraded to the latest firmware could you factory reset that and then set it back to AP mode and see if it is more stable?

As in it doesn't show them on the R2 at all, even offline?

It shows almost everything as offline excluding a few devices, but even devices that are clearly connected (and working, temporarily) show as offline.

Is that for devices just connected to the XR or directly to the R2 as well? If they're connected via the XR it makes more sense why that might occur

Both by the looks of things, but there's no way to tell - before the update you gave me, devices connected via the XR were fine, but both versions still have that disconnection issue.

Have you reserved an IP address for the XR? It's possible a DHCP lease change is what's causing this strange behaviour.

Yep, that's the first thing that I did after setting up the R2.

It's still on and off by the way. We have a couple of new Virgin TV 360 boxes that are constantly disconnecting in the mornings (or in the middle of the night before the morning) and requiring to be fully rebooted to start working again. The XR1000 has logs of "Internet connected" alongside NTP sync logs every 6 hours, could that be related perhaps?

Of the XR1000, R2 or both?

I'll send both later tomorrow anyway.

Thanks for the logs, I can't see anything that shouts out too much on the R2. On the R2 LAN Settings, set the DHCP pool so that the IPs you have given the devices are outside of the range and see if it is better. For example, range = .2 - .250 change to .50 - .250 and ensure devices have an IP between .2 & .49. 

Was that the entirety of the XR log? I imagine so given its in AP mode so it's not doing much.

Yep, that's the entirety of it.

I just set the DHCP pool to .50 - .200, since I have a few reservations on .2 - .10 with the AP (XR1000) on .220 - should this be fine?
