D-Link Router — DHCP Error — What It Means & How to Fix It

What Does This Error Mean?

Your D-Link router is not automatically giving IP addresses to your devices. Without an IP address, devices cannot connect to the internet. This is usually fixed by rebooting the router or checking DHCP settings.

Affected Models

D-Link DIR-615
D-Link DIR-825
D-Link DIR-882
D-Link DIR-2660
D-Link AX1800

Common Causes

DHCP server has been accidentally turned off in the router settings
The DHCP address pool is full — too many devices used up all available addresses
The router firmware has a bug causing DHCP to stop responding
A conflict between the router and another device acting as a DHCP server
Corrupted router settings after a power outage or improper shutdown

How to Fix It

Reboot the router by unplugging it for 30 seconds, then plug it back in.

This clears the most common DHCP glitches instantly.
Log in to the admin panel at 192.168.0.1 and go to Setup, then Network Settings.

Look for the DHCP Server section and make sure it is set to Enabled.
Check the DHCP address pool range — for example, 192.168.0.100 to 192.168.0.200.

If the range is too small for all your devices, expand it.
Look for any other router or modem-router combo on your network that might also be running DHCP.

Two DHCP servers on the same network conflict with each other. Only one should be active.
If the problem continues, perform a factory reset by holding the reset button for 10 seconds.

This clears corrupted settings. You will need to reconfigure your internet connection afterward.

When to Call a Professional

If DHCP keeps turning itself off or stops working after every reboot, the router firmware may be corrupted. A D-Link support technician can help you reflash the firmware safely.

Frequently Asked Questions

What does DHCP do on a router?

DHCP automatically gives each device a unique IP address when it connects. Think of it like a hotel receptionist assigning room numbers to guests. Without DHCP, devices cannot get online.

How do I know if the DHCP server is the problem?

If your device says 'No IP address' or shows 169.254.x.x, DHCP has failed. This address range means your device gave up waiting and assigned itself a fake address. Rebooting the router usually fixes it.

Can I set a static IP address instead of using DHCP?

Yes. You can manually enter an IP address, subnet mask, and gateway on your device. This bypasses the router's DHCP server entirely. However, it is more work to manage than just fixing DHCP.
