ramips: add support for Wavlink WL-WN531A3 The Wavlink WL-WN531A3 is an AC1200 router with 5 fast ethernet ports and one USB 2.0 port. It's also known as Wavlink QUANTUM D4. Hardware -------- SoC: Mediatek MT7628AN RAM: 64MB FLASH: 8MB NOR (GigaDevice GD25Q64CSIG3) ETH: - 5x 10/100 Mbps Ethernet (4x LAN + 1x WAN) WIFI: - 2.4GHz: 1x (integrated in SOC) (2x2:2) - 5GHz: 1x MT7612E (2x2:2) - 4 external antennas BTN: - 1x Reset button - 1x WPS button - 1x Turbo button - 1x Touchlink button - 1x ON/OFF switch LEDS: - 1x Red led (system status) - 1x Blue led (system status) - 7x Blue leds (wifi led + 5 ethernet ports + power) USB: - 1x USB 2.0 port UART: - 57600-8-N-1 J1 O VCC +3,3V (near lan ports) o RX o TX o GND Everything works correctly. Currently there is no firmware update available. Because of this, in order to restore the OEM firmware, you must firstly dump the OEM firmware from your router before you flash the OpenWrt image. Backup the OEM Firmware ----------------------- The following steps are to be intended for users having little to none experience in linux. Obviously there are many ways to backup the OEM firmware, but probably this is the easiest way for this router. Procedure tested on M31A3.V4300.200420 firmware version. 1) Go to http://192.168.10.1/webcmd.shtml 2) Type the following line in the "Command" input box and then press enter: mkdir /etc_ro/lighttpd/www/dev; cp /dev/mtd0ro /etc_ro/lighttpd/www/dev/mtd0ro; ls -la /etc_ro/lighttpd/www/dev/mtd0ro 3) After few seconds in the textarea should appear this output: -rw-r--r-- 1 0 0 8388608 /etc_ro/lighttpd/www/dev/mtd0ro If your output doesn't match mine, stop reading and ask for help in the forum. 4) Open in another tab http://192.168.10.1/dev/mtd0ro to download the content of the whole NOR. If the file size is 0 byte, stop reading and ask for help in the forum. 5) Come back to the http://192.168.10.1/webcmd.shtml webpage and type: rm /etc_ro/lighttpd/www/dev/mtd0ro; for i in 1 2 3 4 ; do cp /dev/mtd${i}ro /etc_ro/lighttpd/www/dev/mtd${i}ro; done; ls -la /etc_ro/lighttpd/www/dev/ 6) After few seconds, in the textarea should appear this output: -rw-r--r-- 1 0 0 196608 mtd1ro -rw-r--r-- 1 0 0 65536 mtd2ro -rw-r--r-- 1 0 0 65536 mtd3ro -rw-r--r-- 1 0 0 8060928 mtd4ro drwxr-xr-x 7 0 0 0 .. drwxr-xr-x 2 0 0 0 . If your output doesn't match mine, stop reading and ask for help in the forum. 7) Open the following links to download the partitions of the OEM FW: http://192.168.10.1/dev/mtd1ro http://192.168.10.1/dev/mtd2ro http://192.168.10.1/dev/mtd3ro http://192.168.10.1/dev/mtd4ro If one (or more) of these files are 0 byte, stop reading and ask for help in the forum. 8) Store these downloaded files in a safe place. 9) Reboot your router to remove any temporary file in ram. Installation ------------ Flash the initramfs image in the OEM firmware interface (http://192.168.10.1/update.shtml). When Openwrt boots, flash the sysupgrade image otherwise you won't be able to keep configuration between reboots. Restore OEM Firmware -------------------- Flash the "mtd4ro" file you previously backed-up directly from LUCI. Warning: Remember to not keep settings! Warning2: Remember to force the flash. Notes ----- 1) Router mac addresses: LAN XX:XX:XX:XX:XX:9B (factory @ 0x28) WAN XX:XX:XX:XX:XX:9C (factory @ 0x2e) WIFI 2G XX:XX:XX:XX:XX:9D (factory @ 0x04) WIFI 5G XX:XX:XX:XX:XX:9E (factory @ 0x8004) LABEL XX:XX:XX:XX:XX:9D 2) There is just one wifi led for both wifi interfaces. It currently shows only the 2.4 GHz wifi activity.
