Please check out the article Flash Layout. It contains an example and a couple of explanations.
If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the mtd command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.
- 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
After adding the device to the repository, correct the missing values in the commands.
- Login as root via SSH on 192.168.1.1
- Use the following commands to upgrade.
cd /tmp/ wget http://http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc sysupgrade /tmp/xxx.abc
- If sysupgrade does not support this router, use the following commands.
cd /tmp/ wget http://http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc mtd write /tmp/xxx.abc linux && reboot
→ 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||192.168.0.1/24|
|vlan0 (eth0.0)||LAN ports (1 to 4)||None|
|vlan1 (eth0.1)||WAN port||DHCP|
This might be wrong.
→ hardware.button on howto use and configure the hardware button(s).
The EnGenius ESR1750 has two buttons. They are Reset and WPS. Here, we merely name the buttons, so we can use them in the above Howto:
I just guessed the names, I haven't actually gotten the real ones yet.

Note: This will void your warranty!
- To remove the case, first flip the router upside-down, so that you can see the four screws holding it together.
- Then, use a screwdriver to remove the screws.
- Flip the router right-side up (EnGenius logo on top) and gently lift the top off.
- Unscrew the two screws holding the circuit board.
- Flip the router over again and pull the bottom casing away from the router (it might get stuck on the ethernet ports).
- Be sure not to lose the WPS button that will almost certainly fall out after removing the back case.
- You should now have access to all the important bits of the router. If you need to access the rest of it, just flip over the circuit board.
→ port.serial general information about the serial port, serial port cable, etc.
Photo of the serial header:
The pins, from left to right:
The serial port on the ESR1750 has a 4-pin 0.1" header pre-soldered to the board, making connecting to it trivial. It uses 3.3V logic levels, so make sure your serial cable either only outputs 3.3V or has a 3.3V mode.
→ port.jtag general information about the JTAG port, JTAG cable, etc.
I don't think this router has any JTAG test points.
