Hi! I resetted the extender and when I started to reconfigure it as an extensor it didn't allow me to put the password there was before, which wasn't the same from the modem´s it was connected to. I cannot find where to do so, when I go to Wireless - extension network I only can put back the SSID but nowhere to change the password, just a message that says ´password is the same from your host password´ 

I need them to be different as they were before, for now I put it as an access point but I have a wire all across my apartment. Can you help me out? I tried from the theter and the webpage and nowhere to change it
