Introduce a new option min_tx_power to configure the minimum permitted max TX power (in dBm) for ACS and DFS channel selection. Imagine the following regulatory rules: * 5180 MHz [36] (21.0 dBm) * 5200 MHz [40] (21.0 dBm) * 5220 MHz [44] (21.0 dBm) * 5240 MHz [48] (21.0 dBm) * 5260 MHz [52] (20.0 dBm) (radar detection) * 5280 MHz [56] (20.0 dBm) (radar detection) * 5300 MHz [60] (20.0 dBm) (radar detection) * 5320 MHz [64] (20.0 dBm) (radar detection) * 5500 MHz [100] (21.0 dBm) (radar detection) * 5520 MHz [104] (21.0 dBm) (radar detection) * 5540 MHz [108] (21.0 dBm) (radar detection) * 5560 MHz [112] (21.0 dBm) (radar detection) * 5580 MHz [116] (21.0 dBm) (radar detection) * 5600 MHz [120] (21.0 dBm) (radar detection) * 5620 MHz [124] (21.0 dBm) (radar detection) * 5640 MHz [128] (21.0 dBm) (radar detection) * 5660 MHz [132] (21.0 dBm) (radar detection) * 5680 MHz [136] (21.0 dBm) (radar detection) * 5700 MHz [140] (21.0 dBm) (radar detection) * 5720 MHz [144] (13.0 dBm) (radar detection) * 5745 MHz [149] (13.0 dBm) * 5765 MHz [153] (13.0 dBm) * 5785 MHz [157] (13.0 dBm) * 5805 MHz [161] (13.0 dBm) * 5825 MHz [165] (13.0 dBm) * 5845 MHz [169] (13.0 dBm) * 5865 MHz [173] (13.0 dBm) When ACS or DFS end up selecting channel 144 or higher, some clients might no longer be able to communicate with the AP due to the TX power being limited to 13 dBm. Setting min_tx_power to 20 will result in hostapd not considering these channels during ACS or after a DFS event.

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.
Sunshine!
Development
To build your own firmware you need a GNU/Linux, BSD or MacOSX 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 python3.6+ 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.
Related Repositories
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.
