Installation

OEM easy installation

Flashing via OEM web interface does not work.

OEM installation using the TFTP method

→ docs:guide-user:installation:generic.flashing.tftp

You can flash via tftp recovery:

serve tftp-recovery image as tp_recovery.bin on 192.168.0.225/24
connect to any Ethernet port
power on the device while holding the reset button
wait at least 8 seconds before releasing reset button. After downloading the new firmware image, the power light should flash for about 3mins, then the device should reboot.

Specific values needed for tftp

Bootloader tftp server IPv4 address	192.168.0.225
Firmware tftp image	Latest OpenWrt release (`NOTE:` Use the image containing the name“tftp” and rename it to `tp_recovery.bin`)
TFTP window start	Power on the device while holding the RESET button for 8secs
Bootloader TFTP client IPv4 address	192.168.0.2

Modem configuration

→ How to use LTE modem in QMI mode for WAN connection

The standard configuration can be used, but DHCP (for IPv4) should be disabled, either in LuCI or in the configuration file (/etc/config/network):

config interface 'wwan'
        option proto 'qmi'
        option device '/dev/cdc-wdm0'
        option apn 'internet'
        option pdptype 'ip'
        option dhcp '0'

Upgrading OpenWrt

→ generic.sysupgrade

LuCI Web Upgrade Process

Browse to http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/ LuCI Upgrade URL
Upload image file for sysupgrade to LuCI
Wait for reboot

Terminal Upgrade Process

If you don't have a GUI (LuCI) available, you can alternatively upgrade via the command line. There are two command line methods for upgrading:

sysupgrade
mtd

Note: It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.

sysupgrade

cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
sysupgrade /tmp/xxx.abc

mtd

If sysupgrade does not support this router, use mtd.

cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
mtd write /tmp/xxx.abc linux && reboot

Debricking

→ generic.debrick

Failsafe mode

→ failsafe_and_factory_reset

Specific Configuration

Network interfaces

The default network configuration is:

Interface Name	Description	Default configuration

vlan0 (eth0.1)	LAN ports (1 to 3)	None
vlan1 (eth0.2)	LAN/WAN port	DHCP
wlan0	WiFi	Disabled
wwan0	Broadband	Not configured

Switch Ports (for VLANs)

Numbers 0-3 are Ports 1-4 as labeled on the unit, number 4 is the Internet (WAN) on the unit, 5 is the internal connection to the router itself. Don't be fooled: Port 1 on the unit is number 3 when configuring VLANs. vlan0 = eth0.0, vlan1 = eth0.1 and so on.

Port	Switch port

LAN 1	1
LAN 2	2
LAN 3	3
LAN 4 / WAN	4
