Have for any reason whatsoever a room from the router away poor Wi-Fi reception, so streaming is no pleasure (dropouts, stuttering). Two floors below in the basement, however still receiving. Range of the router so given per se. Tried the problem with these antennas at least mitigate. 3 stars because of good workmanship and stable fit even when oblique antenna position. But a performance improvement I could see in any room. Before / After the reception quality with various wifi Apps measured. No Difference. Streaming in the next room without improvement. Therefore, at least for me unsuitable. For others (see reviews) there appears to be significant improvements, however. Probably depends on several factors !?
