My WiFi reception was rather weak at about 10m from the box with ceiling beams, floor, doors, etc., between the 2. I have 2 of these antennas connected to a PCI card and MIMO since everything is better. Guaranteed stability: no more cutting. Increased Performance: 2.5 MB / s (20Mbits) constant in FTP copy to my Freebox while I stagnais to 1.9 MB / s (15Mbits) before changing antennas. I forgot: the price is present. A buy eyes closed, your WiFi reception will be necessarily improved.
