Right now If i set this thing on top of my pc or ps3 it will detect the devices but if I move 5 feet away it looses signal. New to this wireless internet stuff and I'm not really digging the mifi 2200 at all. Is there a device I could buy that would give out a stronger signal then mifi 2200 or a device I could connect to the mifi 2200 that would do the job it's supposed to?
