Recently my pbG4 has only picked up wireless networks within a very reduced range of what it normally is capable of. Could my card be going bad, is that possible? Or could it be these "mysterious" networks I found on my airport scanner? Before there was one titled "Jaminator" and every time that was visible (i wasnt connected to it!) my network would drop. Now I get one called "virus_broadcast." I don't notice that my connection drops when this one is visible but i do notice that this started appearing around the time my airport card seems to not connect for crap! While in class, my peers have full connection, i have none. I took out my card and plugged it back in to no avail. Anyone know whats the deal? Thanks!
