I have since a long time a couple of Devolo devices (DLAN Pro 1200+ DINRail and other devices).
I have now installed some Z-.Wave products.
1x AEOTEC ZWave Stick on HP ML-Server
Multiple Fibaro Window Sensors
Multiple Fibaro Motion Sensors
Multiple Fibaro WallPlugs
Since I am using Z-Wave I have big troubles with the Devolo Devices (slow or not responding at all). The only device I can see which could have this impact are the WallPlugs.
Only for future users reading this post too: I have the same issue: no network anymore for devices connected via ethernet or wifi on a Devolo plugged into a Fibaro Wall Plug.
I tried both with a Dlan 500 Wireless+ and a Dlan 200 AV Wireles N.
As soon as I remove the Fibaro Wall plug, the devices get a connection. If I plug again the Dlan into the Wall Plug : connection can’t be established.
The wierd thing is that is used to work for a month or two. I didn’t upgrade the Dlan or the Fibaro. So no idea, what has changed. I did test the Dlan devices with other connected devices to be sure the problem was not there.
Also, while connected on the Fibaro Wall Plug, the Dlan disappear from the Devolo Cockpit application. It reappears as sonn as I remove the Wall Plug.
Voilà. I know this is a very old post, but I couldn’t find a lot of other users experiencing the same issue.
