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
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.
Changes in v2:
- update LED config for LAN/WAN
- disable USB
- drop incorrectly added mt76 from DEVICE_PACKAGES
(wlan is supported by rt2x00)
