The DWR-118-A2 Wireless Router is based on the MT7620A SoC. Specification: - MediaTek MT7620A (580 Mhz) - 128 MB of RAM - 16 MB of FLASH - 1x 802.11bgn radio - 1x 802.11ac radio (MT7612EN) - 4x 10/100 Mbps Ethernet (1 WAN and 3 LAN) - 1x 10/100/1000 Mbps Marvell Ethernet PHY (1 LAN) - 2x external, non-detachable antennas - 1x USB 2.0 - UART (J1) header on PCB (57600 8n1) - 7x LED (5x GPIO-controlled), 2x button - JBOOT bootloader Known issues: - GELAN not working - flash is very slow The status led has been assigned to the dwr-118-a2:green:internet led. At the end of the boot it is switched off and is available for other operation. Work correctly also during sysupgrade operation. Installation: Apply factory image via http web-gui or JBOOT recovery page How to revert to OEM firmware: - push the reset button and turn on the power. Wait until LED start blinking (~10sec.) - upload original factory image via JBOOT http (IP: 192.168.123.254) Signed-off-by: Cezary Jackiewicz <cezary@eko.one.pl> Signed-off-by: Pawel Dembicki <paweldembicki@gmail.com>
