- RAM: 64MB
- Serial: As marked on PCB, 3V3 logic, baudrate is 115200
- Ethernet: 3x 10/100 Mbps (switched, 2x LAN + WAN)
- WIFI0: MT7628AN 2.4GHz 802.11b/g/n
- WIFI1: MT7612EN 5GHz 802.11ac
- Antennas: 4x external (2 per radio), non-detachable
- LEDs: Programmable power-LED (two-colored, yellow/blue)
Non-programmable internet-LED (shows WAN-activity)
- Buttons: Reset
INSTALLATION:
1. Connect to the serial port of the router and power it up.
If you get a prompt asking for boot-mode, go to step 3.
2. Unplug the router after
> Erasing SPI Flash...
> raspi_erase: offs:20000 len:10000
occurs on the serial port. Plug the router back in.
3. At the prompt select option 2 (Load system code then
write to Flash via TFTP.)
4. Enter 192.168.1.1 as the device IP and 192.168.1.2 as the
Server-IP.
5. Connect your computer to LAN1 and assign it as 192.168.1.2/24.
6. Rename the sysupgrade image to test.bin and serve it via TFTP.
7. Enter test.bin on the serial console and press enter.
