Hi,

Its been a while since your post but I have the same issue with my DD-WRT install.

Did you ever figure out why LAN Status shows the DHCP Server disabled even though the DHCP Server is enabled in Basic Setup?

Any feedback is greatly appreciated.

Regards.

DHCP is working for wireless clients, but not LAN.

I've enabled DHCP in Setup.
Setup->Basic Setup->Network Setup

Network Address Server Settings (DHCP)
DHCP Type
DHCP Server
Enable Disable
Start IP Address
10.10.192.
Maximum DHCP Users
Client Lease Time
min
Static DNS 1
...
Static DNS 2
...
Static DNS 3
...

But Status shows it disabled:

Status->LAN

DHCP Status
DHCP Server
Disabled

Is there someplace else I need to enable it.

Welcome to the forum

Please note the forum guidelines:
https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=324087

Reviving old threads is not something which is encouraged.

Always state your build number, there are some bad builds around in the wild.

If you are using a recent (from this month) and know good build you might consider just resetting the router and leave everything at its default settings and then see if it is working.

Alternatively post pictures of Setup page and Services/Services page

Start IP Address
10.10.192.


The fourth octet of the IP address is missing.

It was probably a dirty copy and paste from the webUI from the original post. The original post is here. Whatever the default DD-WRT 4th octet is would probably apply, I presume. Still no valuable information as far as router and build number to help the OP in this thread, but let's break out the magic crystal ball and start guessing, might as well...

I apologize for reviving an old thread - I wasn't aware it is contrary to guidelines - will not repeat.

Firmware: DD-WRT v3.0-r37305 std (10/10/1Cool

Setup page attached.
Status/LAN page attached.
Services/Services page attached.

Thanks for any assistance you can provide.

I'm just going to blindly venture to guess that udhcpd will not start without dnsmasq being enabled in the webUI.
You should probably consider upgrading to a more recent build, clearing nvram / resetting to defaults and configuring from scratch.

Upgrading seems a good advice indeed.

I even think DNSMasq is used for DHCP in modern builds, so you probabaly will not get DHCP when you disable DNSMasq, not sure about this though

You can try disabling dnsmasq in the webUI in more recent builds, but process_monitor will restart it if you kill it, last I knew. I seem to recall that dnsmasq and udhcpd were tied together in the services and process_monitor code or something, so you cannot have one without the other. I could be mistaken, though Wink Cool

Enabling dnsmasq in the webUI seem to work - see attached image - will monitor. Thank you.

DNSMasq is the only DHCP server in newer bilds as udchp is removed.
