Getting started with a new Device Page
- This is an empty template that suggests the information that should be present on a well-constructed Device Page. This means, that you have to fill it with life and information.
- There are several “fixme” tags with text on a light background (like this text) throughout this template. As you fill in the page, remove those tags so that people can judge its completeness.
- When there are no more “fixme” tags left, delete this one too, along with the
<WRAP>that encloses it.
Keep the articles modular
- Please include only model specific information, omit bla,bla and put everything generic into separate articles
- If you have no time to write certain stuff, link to docs
- base-system should lead the way, do not explain this again
- DO NOT provide a complete howto here! Instead groom the general documentation.

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
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
