One of your offsite offices is complaining that part of their wireless network is slow. Once you arrive at their site, you determine one of the access points is receiving 12 Mbps but should be receiving 24 Mbps. The access point is near the office break area. What is the possible reason?
  1. The printer across the room from the break room is interfering with EMI.
  2. The microwave oven in the break room is producing RFI.
  3. The access point is faulty.
  4. The cell phones from employees in the break room are interfering.
Explanation
Answer: B - Since the access point is near the break room, a real potential issue is interference from a microwave.

Key Takeaway: Microwave ovens can produce enough RFI to reduce the efficiency of Wi-Fi networks by a noticeable amount. Move the access point away from the break room but to a location that still covers the office.
