MikroTik LHG-HB platform

Under Construction!
This page is currently under construction. You can edit the article to help completing it.

The LHG-HB platform is the board design based on the Qualcomm Atheros QCA9533 used in various MikroTik wireless devices with 802.11b/g/n radio, 1x 10/100 Mbps Ethernet port, 16 MB SPI NOR flash and 64 MB RAM:

LHG 2 (RBLHG-2nD)
SXTsq Lite2 (RBSXTsq2nD)

and possibly also (untested):

LDF 2 (RBLDF-2nD)
LHG XL 2 (RBLHG-2nD-XL)

The LHG 2 (Light Head Grid) is a compact and light 802.11b/g/n outdoor wireless device with an integrated dual polarisation 18 dBi grid antenna and one 10/100 Mbps Ethernet port for point to point links or for use as a CPE.

The SXTsq Lite2 is a compact and lightweight 802.11b/g/n outdoor wireless device with an integrated 10 dBi antenna for point-to-point links or as a CPE unit, compact, weatherproof and easy to mount.

→ Install OpenWrt (generic explanation)

Please add the installation procedure here.

Find out flash layout, then add the flash layout table here (copy, paste, modify the example).

Please check out the article Flash layout. It contains examples and explanations that describe how to document the flash layout.

The instructions below are for Broadcom devices and only serve as an example.
Remove / modify them if they do not apply to this particular device!

This section deals with

How you install OpenWrt from a device freshly opened
The steps required such as reset to factory defaults if the device has already been configured

Note: Reset router to factory defaults if it has been previously configured.

Browse to http://192.168.1.1/Upgrade.asp
Upload .bin file to router
Wait for it to reboot
Telnet to 192.168.1.1 and set a root password, or browse to http://192.168.1.1 if LuCI is installed.

→ generic.flashing.tftp

Specific values needed for tftp

Enter values for “FILL-IN” below

Bootloader tftp server IPv4 address	FILL-IN
Bootloader MAC address (special)	FILL-IN
Firmware tftp image	Latest OpenWrt release (`NOTE:` Name must contain “tftp”)
TFTP transfer window	FILL-IN seconds
TFTP window start	approximately FILL-IN seconds after power on
TFTP client required IP address	FILL-IN

→ generic.sysupgrade

These are generic instructions. Update with your router's specifics.

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

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

Login as root via SSH on 192.168.1.1, then enter the following commands:

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.

Login as root via SSH on 192.168.1.1, then enter the following commands:

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

→ generic.debrick

→ failsafe_and_factory_reset

→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.

The default network configuration is:

Interface Name	Description	Default configuration
br-lan	LAN & WiFi	192.168.1.1/24
wlan0	WiFi	Disabled

Please fill in real values for this device, then remove the EXAMPLEs

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
Internet (WAN)	EXAMPLE 4
LAN 1	EXAMPLE 3
LAN 2	EXAMPLE 2
LAN 3	EXAMPLE 1
LAN 4	EXAMPLE 0

The MikroTik LHG-HB platform has the following buttons:

BUTTON	Event
Reset	reset

Note: the reset button shares GPIO 16 with the disabled rssihigh LED. To avoid conflicting behaviour, only the button is registered.

The hardware.button page contains information on howto use and configure the hardware button(s). Here, we merely name the buttons, so we can use them in the above Howto.

This table is automatically generated, once the correct filters for Brand and Model are set.
If you see “Nothing.” instead of a table, please edit this section and adjust the filters with the proper Brand and Model. Just try, it's easy.
If you still don't see a table here, or a table filled with '¿': Is there already a Techdata page available for MikroTik LHG-HB platform ? If not: Create one.
If you see a table with the desired device data, everything is OK and you can delete this text and the <WRAP> that encloses it.
If it still doesn't work: Don't panic, calm down, take a deep breath and contact a wiki admin (tmomas) for help.
