devolo dLAN pro 1200+ WiFi ac

The Devolo DLAN pro 1200+ WiFi ac is hardware-wise the same as the DLAN 1200+ WiFi ac (non-pro) variant. The openwrt firmware includes pro in the device name, though it can be flashed on the non-pro version as well.

The DLAN pro 1200+ WiFi ac is a wall-plug device which still exposes the plug. It has Powerline capabilities, which are only useful if the proprietary firmware is added. Other than that, it includes 2 LAN ports and 2.4GHz as well as 5GHz wifi.

1. → Obtain firmware
2. → Install OpenWrt

The method to install OpenWrt depends on the currently running devolo firmware version.

1. If your device is running the “dLAN® pro 1200+ WiFi ac 1.1.1” firmware the OpenWrt image is installed through the native Web UI firmware update page.
2. If it's running a lower firmware version than version 1.1.1 or with a “delos dLAN® pro 1200+ WiFi ac” firmware 3.0.0 or higher, you can either up/downgrade to firmware “dLAN® pro 1200+ WiFi ac 1.1.1” and then execute step 1, or install using the TFTP method below.
3. If it's running a “delos dLAN® pro 1200+ WiFi ac” firmware, you can instead of the TFTP method use sysupgrade with the -F option to install OpenWrt as explained below.

→ generic.sysupgrade

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

• Login as root via SSH on the configured device IP address (static or DHCP) with the Web-UI password, then enter the following commands:

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

If you flashed a wrong image you have to debrick the device.

→ generic.flashing.tftp

1. download the OpenWrt sysupgrade image
2. the image on the TFTP server must be called “uploadfile”
3. setup your TFTP server to use the IP address 192.168.0.100/24
4. connect an ethernet cable between your computer and one of the LAN ports
5. power it up while pushing down the reset button
6. wait until Home/WiFi-LEDs blink red/white a few times and stay on, then release the reset button
7. wait until LEDs stop to blink red/white
8. the device should boot now

If you flashed a wrong image you have to repeat the process with the correct image.

→ generic.sysupgrade

• 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

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:

• sysupgrade
• mtd

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

• 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

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 firmware && reboot

→ generic.debrick

You can flash a new OpenWrt firmware with TFTP → oem_installation_using_the_tftp_method.

→ failsafe_and_factory_reset

→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.

The default network configuration is:

dLAN pro 1200+ WiFi ac uses an Atheros AR8327 switch. Switch ports 1, 5, 6 are not used. The default configuration doesn't use VLANs.

LAN 2 is the interface that's placed next to the reset button.

The Devolo dLAN pro 1200+ WiFi ac has the following buttons:

The Devolo dLAN pro 1200+ WiFi ac has the following LEDs:

The Powerline (PLC) interface of the dLAN pro 1200+ WiFi ac requires 3rd party firmware which is not available from standard OpenWrt package feeds. There will be a package feed on github which you must add to OpenWrt buildroot so you can build a firmware image which supports the plc interface.

For now:

1. Install the build-system. Follow the steps to compile an image.
2. Add the dlan-openwrt feed to your buildroot.
3. Download the firmware from the manufacturer website. Extract it with binwalk.
4. To get the right firmware, you can spot something like MT2673 in top right of the device as seen on this image. For MT2673 you copy the config file 2673.pib and the firmware file nt6x00.nvm to [buildroot]/[trunk]/feeds/dlan/dlan-fw/qca/dlan-pro-1200-ac/
5. Compile
