Hi, I have a TP-Link WPA4220 KIT (V1) that I have been using without any problem for the past year. However I recently changed my ISP and hence I have changed my router and now the TP-link is not working at all: I can neither clone the new wifi nor create a new powerline as I used to do with the old router. The new router is optic fiber and the previous one was ADSL. I have tried several times, and even reset the TP adapter to its default setting but it is not working.

Any ideas? Does this kit not work with optic fiber?

Thx in advance.
