Add thermal zone for the Wi-Fi chip using the same trip levels and cooling maps as the CPU. The kernel thermal governor will act on whichever temperature is the highest. There is only a single heatsink and fan to cover both the SoC and Wi-Fi chip, so tracking both CPU and Wi-Fi temperatures ensures that neither chip will overheat from low fan speed. The trip levels are spaced 1.25C apart with double that (2.5C) for the hysteresis, with 5C hysteresis for the lowest trip level (65C) because it is preferable for the fan to run for longer at low speed than to stop and start repeatedly. In the absence of continuous proportional feedback control, tightly grouping the trip levels and cooling maps minimises the frequency and amplitude of temperature and fan speed oscillations. The cooling states are set to increments of 5 (out of 255) from 12% to 61% and then increments of 10 from 61% to 100% with kick start speed at 15%. In comparison, the default in mt7981b.dtsi starts at 50% fan speed and leads to constant on/off cycles within a short period of time (every ~2 minutes).

OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

Download
Built firmware images are available for many architectures and come with a package selection to be used as WiFi home router. To quickly find a factory image usable to migrate from a vendor stock firmware to OpenWrt, try the Firmware Selector.
If your device is supported, please follow the Info link to see install instructions or consult the support resources listed below.
An advanced user may require additional or specific package. (Toolchain, SDK, ...) For everything else than simple firmware download, try the wiki download page:
Development
To build your own firmware you need a GNU/Linux, BSD or macOS system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.
Requirements
You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.
binutils bzip2 diff find flex gawk gcc-6+ getopt grep install libc-dev libz-dev
make4.1+ perl python3.8+ rsync subversion unzip which
Quickstart
-
Run
./scripts/feeds update -ato obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -ato install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfigto select your preferred configuration for the toolchain, target system & firmware packages. -
Run
maketo build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.

The main repository uses multiple sub-repositories to manage packages of
different categories. All packages are installed via the OpenWrt package
manager called opkg. If you're looking to develop the web interface or port
packages to OpenWrt, please find the fitting repository below.
