@mentalinc, both the receiver (Denon AVR-X1400H) and the TV (LG G3) has separate MACs according to the devices info in the devices list.
I noticed a copy paste error in my post above, which I corrected some minutes ago. I have the LG TV set as two static IPs for the WLAN and LAN, connections respectively.
Static reservations up to .15, and DHCP for .15 to .28. So it should’nt be that either. The TVs LAN and WLAN set for static IP on .12 and .13, respectively (chosen to be able to set a .12/31 firewall rule). Static IP is set on Route10-side.
This is typically caused by a DHCP pool that is too small, or misconfigured static IPs, and will cause intermittent connectivity. Only a few can be shown here, but there may be more.
192.168.11.23: REDACTED_1 REDACTED_2
Some info that may or may not be helpful:
I have no static IPs on that subnet
DHCP lease is set to the default
Apart from the Route 10, all network hardware is Ubiquti
DNS is from a PiHole
I’m running self-hosted Alta controller on Kubernetes running 1.1a, the Route10 is on 1.4f
The devices are a Garmin Edge GPS unit and some Withings/Nokia scales
@mentalinc
I experience the problem to be on wireless devices only. Phones and computers configured with DHCP. I never experienced the IP conflict on Static IP addresses so that may be different from @ebuckland81.
My DHCP Guard is disabled because there is only one DHCP server in the system.
Further the IP conflict is over the whole DHCP range.
@Alta-Jeff But now for 2 days it has gone quiet. No IP conflicts. Has there been any further testing on my system or it just had a good weekend?
@mentalinc I guess it is weekend everywhere.
No I mean that the IP conflicts has stopped during the last 2 days.
I do not know why or what has been changed. We will see when there is more devices connected again during the week.
@Alta-Jeff
I was a little too optimistic that something has resolved it self. But today when there was a few more gadgets in the house I got a new IP address conflict.
