Hey i was sittng in my CIS (computer information systems class) when a teacher came in and told my teacher they have some trouble with the wireless network they are experimenting with . She says this is the problem . A student came in the class and tried to print something the second she pressed the print button all other computer "printer icons" went dimm, that is offline. She also said there is no IP complexity (i dont know if i udnerstood that right) and then they called the IT department. I was just wondering what could cause the problem?
