Auser calls to report that she is experiencing intermittent problems while accessing the wireless network from her laptop computer. she can access the network from her usual office, but today, she is trying to access the wireless network from a conference room, which is across the hall and next to the elevator. what is the most likely cause of her connectivity problem?

Interference of signal and the range between the user and the access point.

Explanation:

Elevators, specifically those with high voltage, are notoriously known for being a source of very strong magnetic fields. They produce a lot of harmonics that causes signal interference and noise. Whenever there is any kind of noise in a network, it causes huge intermittent connection. Also, the farther away the user is from the router or the AP, the weaker the signals and the more the intermittencies.  The user is recommended to be within the edges if the range limit.

 The most likely cause is the obstacles.

Explanation:

Since, the user is experiencing problems intermittently then, it is sure that she is loosing her connectivity again and again. Connection lost can happen because of many issues but here in the given situation it is because of the hall the elevator.

It is difficult for her to device to receive the signal and the strength of signal is lost while reaching the device. As, signal travels from one point to other, it tends to lost the strength thus resulting in poor connection.
