I bought a wifi repeater a few days ago, TL-WPA7617 to be exact and it has been a struggle to get it to work. Whenever I try to link it with my router using the router's wps button, it just completely ceases working and it's own wifi connections dissappear. When I tried it with the tether app, it kept saying router was too far away even though it was not even a meter away and although it had a connection it did not have internet. When I tried just connecting it to the router with an ethernet cable it had both a connection and internet. When this was being sold to me I was told it functions by itself and doesn't need anything else but is that true?
