Again here, same bug, I have three To Link WiFi extenders  connected via WPS to my router. All Tplink , the crazy thing is I can access the extender by its name an all of them deliver internet but if I connect to the router itself a message telling me the router is connected to the Wifi Network without internet access, I tried the clone solution, it worked while the Pc is on but if I turn it off the router internet dissappears but the extenders continues connected to the wifi and with internet. I have tried to analize this situation but finally I gave up.
