There are basically two ways to install the Gargoyle firmware onto your router:
Gargoyle images are available for many routers, and installation instructions are available for several models:
Gargoyle will likely run on many other routers supported by OpenWRT but you will need to research more carefully.
Gargoyle should run on any router that uses a mips architecture, has either a Broadcom or Atheros based wireless card, and has at least 4MB of flash. You may try installing the gargoyle images (AT YOUR OWN RISK) for these routers, or, more wisely, you may try installing OpenWrt broadcom-2.4 images or atheros-2.6 images on these routers, and if you get this working, install the Gargoyle packages on top of it. Consult the OpenWrt Table of Hardware to determine whether your router is compatible with OpenWrt and whether it is likely to be compatible with Gargoyle based on the criteria listed above.
Be VERY careful of the 4MB flash memory requirement. Most newer WRT54G models have only 2MB, making installation of Gargoyle/OpenWrt impossible
Connecting to a Gargoyle Image
If you install a Gargoyle image then the initial connection procedure is a little different than for OpenWrt.
- browse to 192.168.1.1 and enter the default “password”.
- ssh firstname.lastname@example.org with the default “password”.
OpenWrt defaults to having no root password and telnet is available. Telnet is not available on Gargoyle installed from an image.
Migrating from DD-WRT
Attempts to load a Gargoyle image directly from the DD-WRT GUI have been unsuccessful. However, downloads are available to revert from DD-WRT to Stock Factory firmware, and from there a Gargoyle image may be loaded.
If you find the documentation here insufficient there are several other resources on installing OpenWrt you may find helpful. In fact, much of the information provided here was derived from these sites:
