**Netgear LBR20** is a router with two gigabit ethernets , three wifi radios and integrated LTE cat.18 modem. SoC Type: Qualcomm IPQ4019 RAM: 512 MiB Flash: 256 MiB , SLC NAND, 2 Gbit (Macronix MX30LF2G18AC) Bootloader: U-Boot Modem: LTE CAT.18 Quectel EG-18EA , Max. 1.2Gbps downlink / 150Mbps uplink WiFi class AC2200: - radio0 : 5G on QCA9888 , WiFi5- 802.11a/n/ac MU-MIMO 2x2 , 887Mbps , 80MHz - limited for low channels - radio1: 2,4G on IPQ4019 ,WiFi4- 802.11b/g/n MIMO2x2 300Mbps 40Mhz - radio2: 5G on IPQ4019 , WiFi5- 802.11a/n/ac MU-MIMO 2x2 , 887Mbps ,80Mhz - limited for high channels (from 100 up to 165) . 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.
