Configuration just a Power-LAN network with more than 2 Plugs is not quite trivial,
but if you just let me know about it works very well with the utlity tool.
You must stop copy the password from the housing from any device and then
Add information about the utility to plug it. So you do it then with the WPA281.
The name of the Power-LAN network must be distributed to all plugs, otherwise they will lose again.
Then call the specified IP in the Web browser and configure the WLAN of WPA281.
Here set the same SID as the main wireless router and the existing
same encryption, that's it. Even the WLAN transmits throughout the house.
