What is the “failed to obtain an IP address” error?

Failing to obtain an IP address error is a type of network connection problem that can occur when attempting to connect to the internet. This problem occurs because your device cannot receive an Internet Protocol (IP) address from a network router or modem.

What causes failure to obtain an IP address?

When a computer or other device fails to obtain an IP address, it can be caused by several different things.

Router issues

The most common problem is the network’s router or modem, the source of all network traffic. This could include a router that has been incorrectly configured or a modem that is not working correctly.

Faulty cable

Another common cause of failed IP address requests is faulty cabling between the router and the computer or device requesting it. Loose cables, frayed wires, incorrect connectors, and bad connections can all cause poor performance on your network.

DHCP malfunction

The DHCP server associated with the router may also malfunction or have been incorrectly configured. If this happens, the router cannot assign any computers an IP address.

Wrongly assigned static IP address

Finally, the computer or device uses a static IP address already assigned to another machine on the network. This will cause an IP address conflict, preventing Internet access for either device.
