Hi
Thanks for the reply!

I already tried this tool but the problem is, I got Version 1.1 of TL-PA4020P.
If I download this tool and try to start it, there is nothing going on. Programm didn´t start in my Win7. :mad:

can you see the powerline showed in the utility?
if you can,just click the "security" icon on the left of utility and change the network name,it is the powerline password
(I guess you may have midunderstood this,Once the new network name is established, all the other powerline network devices will be given the new name so they can communicate with each other)

here's a FAQ but it's the old utility with green interface:

I want to edit device pass NOT the network pass. As I wrote in my first post its a security problem to stay at the password which is printed on the backside of the device. If u want, take a look at this link I found: https://www.bentasker.co.uk/documentation/security/282-infiltrating-a-network-via-powerline-homeplugav-adapters So u see whats my Problem...

The powerline key(password) can not be changed.
as is wrote in your link : It does, of course require some proximity to the target network
do you think hackers would come close to your house and take efforts trying to attack your network?why would they?and how can they easily get into your circuit?

and as wrote: The encryption key on the target network has been changed from the default (otherwise things are much, much easier). The quick setup guide for most of these devices advises pushing the encryption reset buttons, so it's likely most users have changed from the commonly known default (HomePlugAV).

if you still worry about it, just change your network name regularly.
