Becouse of DFS remember to set country before turning on. Ethernet: 2x1GbE (WAN/LAN1, LAN2) LEDs: section power : green and red , section on top (orbi) drived by TLC59208F: red, green ,blue and white USB ports: No Buttons: 2 Reset and SYNC(WPS) Power: 12 VDC, 2,5 A Connector type: Barrel OpenWRT Installation 1. Simplest way is just do upgrade from webpage with *factory.img 2. You can also do it with standard tool for Netgear's debricking - NMPRFlash 3. Most advanced way is to open device , connect to UART console and : - Prepare OpenWrt initramfs image in TFTP server root (server IP 192.168.1.10) - Connect serial console (115200,8n1) to UART connector - Connect TFTP server to RJ-45 port - Stop in u-Boot and run u-Boot command: > setenv serverip 192.168.1.10 > set fdt_high 0x85000000 > tftpboot 0x83000000 openwrt-ipq40xx-generic-netgear_lbr20-initramfs-zImage.itb > bootm 0x83000000 - Login via ssh - upload or download *sysupgrade.bin ( like wget ... or scp transfer) - Install image via "sysupgrade -n" (like “sysupgrade -n /tmp/openwrt-ipq40xx-generic-netgear_lbr20-squashfs-sysupgrade.bin”) Back to Stock - Download firmware from official Netgear's webpage , it will be *.img file after decompressing. - Use NMRPFlash tool ( detailed insructions on project page https://github.com/jclehner/nmrpflash ) Open the case - Unscrew nuts and remove washers from antenna's conectors. - There are two Torx T10 screws under the label next to antenna conectors. You have to unglue this label from left and right corner to get it - Two parts of shell covers will slide out from eachother , you have to unglue two small rubber pads and namplate sticker on bottom to do that. - PCB is screwed with 4Pcs of Torx T10 screws - Before lifting up PCB remove pigtiles for LTE antennas and release them from PCB and radiator (black and white wires) - On other side of PCB ,in left bottom corner there is already soldered with 4 pins UART connector for console. Counting from left it is +3,3V , TX , RX ,GND (reffer to this picture: https://i.ibb.co/Pmrf9KB/20240116-103524.jpg ) BDF's files are in firmware_qca-wireless https://github.com/openwrt/firmware_qca-wireless/ and in parallel sent to ath10k@lists.infradead.org.

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 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 python3.7+ rsync subversion unzip which
Quickstart
-
Run
./scripts/feeds update -a
to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -a
to install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfig
to select your preferred configuration for the toolchain, target system & firmware packages. -
Run
make
to 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.
