Installation
Flashing ANY Firmware
You must set your TCP/IP v4 protocol at your computer to:
- IP: 192.168.1.2
- Netmask: 255.255.255.0
- Gateway: 192.168.1.1
- DNS: (optional, can be blank).
Then:
- Power off the router.
- Press reset button near the antenna.
- Keep it pressed while powering up during ~20+ seconds.
- Acces to http://192.168.1.1 and upload binary file.
- Wait until router reboots.
Specific Configuration
Interfaces
The default network configuration is:
| Interface Name | Description | Default configuration |
|---|---|---|
| br-lan | LAN & WiFi | 192.168.1.1/24 |
| eth0.1 | LAN ports (1 to 4) | bridged |
| eth0.2 | WAN port (WAN) | nat (WAN) |
| wlan0 | WiFi | bridged (disabled) |
| wlan1 | WiFi | bridged (disabled) |
Switch Ports (for VLANs)
This is an example to configure the switch: numbers 0-2 will be lan, labeled as Ports LAN1X, LAN2X, LAN3X on the unit, number 3 (LAN4X) will be the Internet (WAN), 8 is the internal connection to the router itself. Don't be fooled: vlan1 = eth0.1, vlan2 = eth0.2 and so on.
| Port | Switch port | Mode |
|---|---|---|
| 1 | 0 | lan |
| 2 | 1 | lan |
| 3 | 2 | lan |
| 4 | 3 | lan |
| WAN | 4  | Internet (WAN) |
| n/a | 5t | to CPU |
