The OpenWrt community is proud to announce the newest stable release of the OpenWrt 23.05 stable series.

Download firmware images via the Firmware Selector or directly from our download servers:

• Download firmware image for your device (firmware selector)
• Download firmware images directly from OpenWrt download servers

An upgrade from OpenWrt 22.03 to OpenWrt 23.05 is supported in many cases with the help of the sysupgrade utility which will also attempt to preserve the configuration. A configuration backup is advised nonetheless when upgrading to OpenWrt 23.05. (see “Upgrading” below).

The OpenWrt Project is a Linux operating system targeting embedded devices. It is a complete replacement for the vendor-supplied firmware of a wide range of wireless routers and non-network devices. See the Table of Hardware for supported devices. For more information about OpenWrt project organization, see the About OpenWrt pages.
