Netgear Router — DHCP Failure Error Explained & Fixed

What Does This Error Mean?

DHCP is the system your router uses to hand out an address to each device on your network — like giving everyone a house number on the street. When DHCP fails, your devices cannot get an address and cannot connect to the internet. This usually shows up as 'No Internet Access' or 'Limited Connectivity' on your computer or phone.

Affected Models

Netgear Nighthawk Series
Netgear Orbi
Netgear R7000
Netgear R6400
Most Netgear home routers

Common Causes

The router's DHCP server has crashed or frozen
Too many devices are connected and the router ran out of available addresses
Another device on the network is acting as a second DHCP server and causing a conflict
The router firmware has a bug affecting the DHCP function
The router has been running for weeks without a restart and its memory is full

How to Fix It

Restart your Netgear router by unplugging the power cable, waiting 30 seconds, and plugging it back in. Wait two minutes.

This clears the router's memory and resets the DHCP service. It fixes the problem most of the time.
On the device that cannot connect, forget the Wi-Fi network and reconnect. This forces the device to request a fresh address.

On iPhone: Settings > Wi-Fi > tap the network name > Forget This Network. On Android: Settings > Wi-Fi > hold the network name > Forget.
Log into your router at routerlogin.net. Go to Advanced > Setup > LAN Setup and confirm DHCP is enabled.

The DHCP server switch should be set to 'On' or 'Enable'. If it is off, turn it on and save.
While in LAN Setup, check the address pool. Make sure the starting and ending IP addresses allow enough room for all your devices.

A typical home setting is 192.168.1.2 to 192.168.1.254, which supports up to 253 devices.
If nothing else works, press and hold the router's Reset button for 10 seconds to restore factory settings. Then set it up again.

A factory reset erases your Wi-Fi name and password. Have your internet provider details ready to reconnect.

When to Call a Professional

DHCP errors are almost always fixable at home. If you have followed all the steps and devices still cannot connect, contact Netgear support at netgear.com/support. In rare cases, the router's internal settings may need a full factory reset.

Frequently Asked Questions

What does 'DHCP' actually mean?

DHCP stands for Dynamic Host Configuration Protocol. In simple terms, it is the part of your router that automatically gives each device a unique number so they can communicate on the network. Without it, your devices are like houses with no addresses — they cannot send or receive data.

My phone connects fine but my laptop cannot. Is that a DHCP problem?

It could be. If some devices work and others do not, the router may have run out of available addresses. Try restarting the router and then reconnecting the laptop. Also check if the laptop has a manually set IP address that is conflicting.

Will a factory reset fix a DHCP error?

In most cases, yes. A factory reset returns all settings to their original state, which clears any misconfigured DHCP settings. However, you will need to set up your Wi-Fi name and password again afterwards.
