169.254 IP address in Windows 11: diagnose DHCP before resetting the network

A 169.254.x.x IPv4 address is a strong clue that Windows did not receive a usable DHCP address from the router or DHCP server.

Applies to: Windows 11Change risk: Low to mediumReviewed: 2026-09-17

Do this first

Run ipconfig /all and identify the active adapter.
Confirm the IPv4 address really begins with 169.254 and note whether a default gateway is present.
Check whether another device gets a normal address from the same router/network.
Reconnect the affected adapter once before changing drivers or resetting the whole network stack.

What this problem usually means

Microsoft explicitly notes that an address in the 169.254.x.x range means Windows could not obtain an IP address from the router. This makes DHCP/link diagnosis more useful than jumping straight to DNS or browser repair.

Ordered repair path

Work from the narrowest fix to the broader one.

Renew the DHCP lease

Low risk

Why this belongs here: Microsoft includes release/renew in the Windows connectivity path when IP assignment is the problem.

Open Terminal or Command Prompt as administrator.
Release the current lease.
Request a new lease.
Run ipconfig again and check whether the address changed to the network’s normal range.

ipconfig /release
ipconfig /renew

Separate router/DHCP failure from a PC-only adapter problem

Low risk

Why this belongs here: If several devices receive self-assigned addresses, the fault is more likely upstream than Windows on one PC.

Test another device on the same Wi-Fi or Ethernet network.
Restart the router only if multiple devices are affected and you control the network.
If other devices obtain normal addresses, return to the affected PC and inspect its adapter/driver.

Use adapter-driver or network reset only after DHCP evidence stays PC-specific

Medium risk

Why this belongs here: Driver reinstall or Network reset is broader than renewing a lease and should come after the physical/router branch is separated.

Check Device Manager for the affected network adapter and any status code.
Update or reinstall only that adapter if the evidence supports it.
Keep Settings > Network & internet > Advanced network settings > Network reset as a later broad software step.

Stop condition

When this guide stops being the right path

If multiple devices cannot obtain normal IP addresses from the same network, stop treating this as a Windows-only problem and troubleshoot the router, DHCP server or network administrator path.

If the problem is still not fixed

If the PC receives a normal private IP address and default gateway but names still do not resolve, move to the DNS-resolution guide.
