What 169.254.x.x means
The range 169.254.0.0/16 is reserved for local auto-configuration. The system uses it when no actionable DHCP response arrives. This address is sometimes used to communicate on the local link, but it does not normally provide access to the Internet.
Immediate checks
Check the cable or Wi-Fi, then confirm that other devices are reaching the network. Disable and re-enable the interface, without randomly changing the IP settings. If all devices are affected, check the router, router or DHCP server as a priority.
Clean Refresh Configuration
A reconnection to the network or a renewal of the DHCP lease may be sufficient after service is restored. If the problem returns, look for a disabled DHCP server, a failed relay, an incorrect VLAN, or filtering between the client and the server.
When to use a manual address
A static configuration is only relevant if you know the expected subnet, gateway, and DNS. It can temporarily hide the DHCP failure, but create a conflict if the chosen address belongs to the dynamic pool.
