Flashing OpenWrt

This device is NOT RECOMMENDED for future use with OpenWrt due to low flash/ram. DO NOT BUY DEVICES WITH 4MB FLASH / 32MB RAM if you intend to flash an up-to-date and secure OpenWrt version onto it! See 4/32 warning for details.

This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation. This means that even setting a password or changing simple network settings might not be possible any more, rendering the device effectively useless. See OpenWrt on 4/32 devices what you can do now.

OpenWrt support for this device has ended in 2022.
19.07.10 was the last official build for 4/32 devices.

Devices with Broadcom WiFi chipsets have limited OpenWrt supportability (due to limited FLOSS driver availability for Broadcom chips). Consider this when choosing a device to buy, or when deciding to flash OpenWrt on your device because it is listed as supported. See Broadcom WiFi for details.

On the OpenWrt ToH (techdata entry)
Support started version: 17.01.0
Current supported version: 22.03.5
