I am still having my problem with 109 wifi radios around my location, all with low signal.
I live in a apartment complex that provides free internet, but signal is very low at my location. The owner tells me it is what it is!
I do not have the option of geting my personal ISP.
My question is: Does anyone has any experience with USB wifi antenas for my MacBook Air?
See my wifi scan: How can I disable automatic scanning for WiFi networks?
