Thanks to your persuasive skills, the medical instrument company took a few days to improve its cable management practices. That’s fortunate, because now, several months later, it has just won a huge contract and its network will expand. The brand-new warehouse is busy with activity. The inventory shelves are being stocked to the ceiling. Nearby, machines that carry merchandise along a conveyor belt are working nonstop. However, the company has a new problem: Since production has stepped up, several inventory specialists in the warehouse are complaining that occasionally their handheld computers will not connect to the network or that they suddenly lose their connection. It’s especially frustrating because more personnel than ever are trying to use the network. What could be causing the handheld computers to experience intermittent connectivity problems? What can you do to rule out the possibility that the handheld computers are simply faulty?
