This is a variant of the MT7620N-based Asus routers. Specifications: - MT7620N (580 MHz) - 32 MB RAM - 8 MB Flash - 5x 10/100Mbps Ethernet (built-in switch) - 2.4 GHz WLAN - 2x external, non-detachable antennas - UART (J2) header on PCB (115200 8n1) Flash instructions: 1. Configure PC with static IP 192.168.1.75/24 2. Connect PC with one of LAN ports, press the reset button, power up the router and keep button pressed for around 6-7 seconds. All 4 LEDs will start to blink, which is when the router will accept firmware files via TFTP. No known limitations on firmware filenames, just send it with a TFTP client to 192.168.1.1. 3. Router will download file from server, write it to flash and reboot. Signed-off-by: Zoltan HERPAI <wigyori@uid0.hu>master
