A user moves to a new desk that is located next to the kitchen. Now, the user can no longer log in to the wireless network. Which of the following is causing this issue?
Wireless interference is often caused by environmental factors such as proximity to kitchens, which may contain microwaves and other electronic devices operating on the same 2.4 GHz frequency used by many Wi-Fi networks. The CompTIA ITF+ FC0-U71 Official Study Guide explains:
“Wireless signals are subject to interference from physical objects, walls, appliances, and other electronic devices operating on the same frequency.”
“Microwave ovens and cordless phones are common sources of interference for Wi-Fi networks.”
In this case, the user's proximity to the kitchen is causing interference, not access control or standards issues.
