Can't assign DHCP

Hi,

In my system logs, I'm seeing the following:

Fri Aug 13 11:50:52 2021 daemon.warn dnsmasq-dhcp[18707]: Ignoring domain XXXGROUP.YYYY.COM for DHCP host name SOMEMACHINENAME

I suspect that due to the above, dnsmasq is not assigning a DHCP IP to the host: SOMEMACHINENAME

How do I configure my existing dnsmasq so that it can assign an IP to the host SOMEMACHINENAME?

I think: https://forum.openwrt.org/t/dhcp-domain-suffix/3353 might be the answer, but I don't understand the solution at all.

Thanks!

Based on the answer, probably this one.... https://openwrt.org/docs/guide-user/base-system/dhcp_configuration#dhcp_options

Obviously you can use other values than the ones listed in the example, too, like 15.

Thanks for your response, unfortunately, I don't understand it.

What do I do in order to add the domain so that dnsmasq can assign an IP to the host?

You need to add the parameter to the dhcp, with whatever value you require.

uci add_list dhcp.lan.dhcp_option="15,bleh.com"
uci commit dhcp
etc/init.d/dnsmasq restart

If this is a setting for a specific MAC, you will need to use the example below the one I linked to, on the same page.

I can also see that message in my logs, but DNSMASQ issues IP addresses anyway. Perhaps there is another reason why it does not work for you.

Enable logging on the DHCP, and post here the full log from a negotiation.

My apologies for using the wrong term. On the affected machine, the error reads "Acquiring IP" after it "established connection".

The net effect is that it fails to connect to the wifi.

Any ideas how I can correct this?

start by trying to catch it in the logs, if unable, use tcpdump, wireshark or cloudshark.

or if you only want to get rid of the issue, set a static IP on the affected host.

No need to apologize, just wanted to clarify the situation.

Is this happening with your WRT1900AC? Is the client having issues an IoT / smart-something device, perhaps?

I tried this before creating this topic, but still, the affected machine had issues connecting to the wifi.

It's a laptop that's having trouble connecting to the WRT1900AC through wifi.

This could be an issue with the router, this series are known to have many similar issues.
