I travel with a USB wifi dongle and one of these directional antennas: http://www.newegg.com/Product/Product.aspx?Item=N82E16833164110
Lately I've noticed there are some APs that my laptop's internal wifi connects to perfectly, but the external antenna can't find whatsoever, even after a lot of directional experimentation. I've tried 2 different USB dongles with the same result. Has anyone had a similar experience? I'm baffled because the external antenna is able to make strong connections to some APs, but it can't even find others that the laptop's internal card finds and connects to no problem. - Grant
