I don´t know how that would change the fact that my router has taken over the ip address of the powerline.
If allready done as you describe and i land on the configuration software from my router if i put in the ip of the powerline

One last time: Disconnect the thing from the router's network, and then configure it through a direct LAN connection, such that it integrates into the router's network properly. THEN bring it back into said network.

If allready done as you describe and i land on the configuration software from my router if i put in the ip of the powerline

To make things even more clearer.

1. I have reseted the powerline
2. I have unpluged the powerline from everything- the powersocket - the router- everything!
3. I directly connect the powerline to my pc via lan cable
4. I put in the ip adress of that is written on the back of the powerline adapter in my browser

aaaaaand

I land on my router.!.. so what am i missing here.? Because the ip that is written on the back of the powerline- is the ip of my router...

So either i change the ip of my router- of which i have no clue how to do- or i have to change the ip of the powerline - for which i have to access the powerline i guesss...

Is that now clear enough?

And can maybe someone else maybe please jump in and point out who misunderstand what in this discussion- because what you told me to do Peter- i allready tryed befor writing this post....

Quite obviously you need to disconnect the PC from the router's network too, such that you can engage a direct connection to the unconfigured WLAN AP. You may need to assign your PC's LAN port a static IP address within the same address range that the WLAN AP uses.

These are all network configuration basics really - so if this continues to be over your head, I suggest you seek help locally, from someone who can physically sit down to your equipment and teach you on the spot.

Hahah Peter - you are a funny guy - network configurations basics? Well for you maybe- the rest of us - this is advanced stuff- i´m pretty computer savy- but you cannot no everything.

You may need to assign your PC's LAN port a static IP address within the same address range that the WLAN AP uses.

I don´t have a clue on how to do this - i will just turn of my router. hook the powerline up to my pc and tell you what happens....

Nothing will happen, for your PC will not be able to receive an IP address from anywhere. You need to configure a static IP address in the same range as the AP's default IP address.
