Title: CJinCA
Review: The antenna helped a bit with my son's PC that was distant from the router. Receive speed now varies from 28 to 54 MBS and does not drop out as much. That's an improvement from the 14 to 28 MBS we had before the antenna. I think it would work even better if we had bought the cable and antenna stand to relocate it all to a better place (eg, off the floor and behind the tower). That by itself might have worked as well as replacing the antenna.
