Specification: - SoC: MediaTek MT7620A (580 MHz) - RAM: 64 MiB (Winbond W9751G6JB-25) - Flash: 16 MiB (Spansion S25FL128SAIF00) - LAN: x4 100M - WAN: x1 100M - Others: USB 2.0, reset button, wps button and 9 LEDs Issues: - 5 GHz band is not functional (missing driver support) Installation: Asus windows recovery tool: - install the Asus firmware restoration utility - unplug the router, hold the reset button while powering it on - release when the power LED flashes slowly - specify a static IP on your computer: IP address: 192.168.1.75; Subnet mask 255.255.255.0 - Start the Asus firmware restoration utility, specify the sysupgrade image, and press upload TFTP Recovery method: - set computer to a static ip, 192.168.1.75 - connect computer to the LAN 1 port of the router - hold the reset button while powering on the router for a few seconds - send firmware image using a tftp client; i.e from linux: $ tftp tftp> binary tftp> connect 192.168.1.1 tftp> put lede-ramips-mt7620-rt-ac51u-squashfs-sysupgrade.bin tftp> quit Signed-off-by: Ørjan Malde <foxyred333@gmail.com>master
