Without antenna I got 2 bars with this antenna without internet. It would be better not to use an antenna than to connect this antenna to my modem, find out! Either they sent me a defective model, or the characteristics of these antennas are so poor that it is not worth buying at all. My opinion is that I wouldn't buy them again if they were only a dollar. It was wasted money. I would not recommend anyone to buy these.
