We just changed our ISP from movistar to vodafone. The vodafone is working fine but the extender has no internet. I can't tell if it is connecting to the router or not, but guessing not as it has no internet. I tried pressing the WPS on both the vodafone boxes (there is a black vertical box and a white horizontal), mulitple times, then pressing the WPS on the extender. Nothing works. The extender flashes a green lock symbol. I tried can't log in online to configure the extender, because it not connected to the internet. I tried using an ethernet cable between the router and the extender and pressing the WPS buttons but nothing happened, except for the lock symbol flashing again. I assume this is because the extender is still configured to the old network, but the old network isn't switched on. Please help.
