I did the wps setup through my router as i got nowhere trying to do it thru the wps button. Seems with my router that button also resets and takes away the password i set and thats no good. Anyway seemed to have worked but then i moved the extender to where i wanted it . Tried to connect my android phone to it and it said 'authentication problem under it. My router connects fine just not the extender. I put in my password, it saved and seemed to be ok but then i saw that error. The extender is in range of the router in the new location. My router is a tp-link tl-wr841n
