devolo Magic 2 WiFi

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

The devolo Magic 2 WiFi was the original MIPS device in the Magic 2 series sometimes referred to as v1. It combines 802.11ac WiFi with G.hn powerline networking and two gigabit LAN ports. It was somewhat quickly succeeded by the devolo Magic 2 WiFi next which is an ARM device with very different hardware. Right now G.hn Powerline support is not working with mainline OpenWrt for this device. A patch is available here and allows it to work with external packages taken from Devolo's firmware.

Any text with a light background (like this one) provides instructions for creating the Details Page. When you have filled in correct/useful information (instead of any template that's there) remove the instructions, as well as the <WRAP> that encloses it.

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.

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 devolo Magic 2 WiFi , 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
1. the dataentry page for devolo Magic 2 WiFi 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.
2. 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.

Experimental Versions

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://192.168.1.1 if LuCI is installed.

OEM installation using the TFTP method

See the commit message that adds device support. Please note that the information about PLC/G.hn there is not accurate and this will stop working after flashing mainline OpenWrt!

Upgrading OpenWrt

→ generic.sysupgrade

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.

Note: It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.

sysupgrade

cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
sysupgrade /tmp/xxx.abc

Specific Configuration

G.hn

Despite what the original Git commit that adds support seems to hint, it is not possible to use G.hn Powerline with this device with mainline OpenWrt as of now.

It is possible to create a set of packages from the Devolo firmware with the scripts provided here: https://codeberg.org/jschwart/devolo-extract-ghn-packages

The G.hn chip needs to be initialized from the OpenWrt side each time the device is powered on. This is handled by the packages from the Devolo firmware. Because of limitations when the chip is not yet initialized, this process can only be done when the switch is configured for 100 MBit/s ethernet. By default it runs at 1 GBit/s. This device is not yet ported to DSA, it relies on `swconfig` to switch the speed. The Devolo provided sources contain specific code that enables this, a first port to OpenWrt mainline is here. Building OpenWrt with this commit allows G.hn to work with the packages generated from the Devolo firmware.

Network interfaces

The default network configuration is:

Interface Name	Description	Default configuration
br-lan	LAN & WiFi	192.168.1.1/24
eth0.1	G.hn	WAN
eth0.2	LAN port	attached to br-lan

Switch Ports (for VLANs)

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
