Help Interpreting System Log Message on EX3301

Griswold

I'm getting a lot of messages of the same type in my System Log, each relating to different ip addresses on my WLAN.

Here's a typical example, can anyone help with interpreting what is going on please?

Many thanks in advance.

You're welcome @Griswold

I think that it is because some device is asking. It might not be on your WiFi though, and unfortunately I cannot tell the maker of the device, because 26:42:01 is not a registered IEEE OUI (so it is probably a randomly generated one.)

If you are confident that you are using static addresses for all of your devices, then you could disable DHCP for LAN setup on your EX3301 router. See below screenshot from the user guide available at

Hi @Griswold

Welcome to the forum.

The messages in the screenshot you have posted are related to your router giving out IP addresses to the devices on your WIFi by DHCP ( Dynamic Host Configuration Protocol), in this giving out 192.168.1.246

I hope that this is helpful.

Kind regards Tony

Thanks Tony.

I wonder why the router is trying, and I assume given the error portion of the message failing, to give out ip addresses as I've assigned static ip addresses to all the devices on my network.

Thanks again Tony.

The device in my example is a Sky Q Box, but it wasn't the only device where this was happening. In fact it was pretty much every device on my WLAN, most of which are served via a TP Link 650 WiFi Extender.

Ethernet directly cabled devices were, obviously, not affected by this.

Disabling DHCP has certainly rectified the problem and there are now no such items in the System Log, though I'm still puzzled why the router would be trying to use DHCP when all devices have static addresses.

Thanks again for your help Tony, I'll mark your post was the solution.

Best Regards
