Supported Versions
- The tables below are automatically generated, once the correct filters for Brand and Model are set.
- If the tables below show information for
Cudy LT400E v1, everything is OK and you can delete this text and the<WRAP>that encloses it. - If the tables below contain “Nothing found”, it means that either
- the dataentry page for Cudy LT400E v1 is missing. Please create a new dataentry page first, then reload this page. The tables should then contain $something. If they do, delete this text and the
<WRAP>that encloses it. - filters are not set correctly. Most common reason for “Nothing found”: The dataentry does not contain a Version, but we are filtering here for version → Please edit this section and adjust the filters with the proper Brand, Model and Version. In case the dataentry does not contain a version, delete the line
filter : Versions~. Just try, it's easy. The tables should then contain $something. If they do, delete this text and the<WRAP>that encloses it.
- If the tables still contain “Nothing found”: Don't panic, calm down, take a deep breath and contact a wiki admin (tmomas) for help.

Hardware Highlights
Installation
The manufacturer's stock firmware is based on OpenWrt and implements a signature check when flashing a new firmware file. The manufacturer provides an intermediate OpenWrt firmware that disables the check and allows flashing a regular OpenWrt image.
→ Install OpenWrt (generic explanation)
Please add the installation procedure here.
Flash Layout
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.
OEM easy installation
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://192.168.1.1if LuCI is installed.
OEM installation using the TFTP method
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 |
Upgrading OpenWrt
These are generic instructions. Update with your router's specifics.
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:
sysupgrademtd
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
