Did you extract the folder after you download it? What's the current hardware and firmware of your router? Is it an EU version as well?

Is it Mac 10.12? It's compatible with Mac. Do you try another computer or your phone?

what's the model number of the power bank? most power banks just charge your phone once it's plugged in, no need to push any button

I guess you have pushed the button to pair them. How about add the new ones with utility http://www.tp-link.com/en/faq-1615.html

Do both powerline LEDs light up? If no, need to pair them. If yes, connect a pc to your router to test the internet. Replug the powerline. It should work if your router is working, no need to set IP...
