Caveat: absolute buy recommendation! The repeater is in many tests the best, more expensive items were left behind. Without the others to know, I believe that too. Easy start-up, even for laymen, as I am. There are 3 ways to install. Since I have no Fritz router, I chose to manually install (all installation options are clearly explained in the enclosed booklet!) Installation took about 5-7 minutes! Really not rocket science! Now the decisive: in border zones have full Wi-Fi and reception in areas where previously there was none at all now! Am more than satisfied! My brother bought immediately also with him and it went smoothly! Hope it helps you with your purchase decision!
