I thought my ibook had a software problem BUT i was adjusting the angle of the screen when i noticed i could connect to my wireless network. I then did some tests and have discovered that i CAN connect to my wireless network but only if the ibook screen is at a certain angle. If i open it a little less than 90 degrees, it will work. any more than that, the signal goes dead..also if the laptop is not open enough, there will be no signal either. it is only at a few angles that are a little less then 90 degrees where i can receive a signal. is this a common problem with an easy fix?
