During lunch time in the break room of a company, Wi-Fi connectivity on the 2.4 GHz band becomes intermittent. At other times of the day, it works fine. What is the most likely cause of this issue?
A.
Employees are using their cell data instead of using the Wi-Fi
B.
The AP in the cafeteria keeps rebooting due to lack of PoE budget on the switch
C.
Toasters and ovens are heating up the air, raising the noise floor with the Wi-Fi on the 2.4 GHz band
D.
Microwaves in the cafeteria are interfering with the Wi-Fi on the 2.4 GHz band
Microwave ovens operate at frequencies around 2.45 GHz, which can cause interference with Wi-Fi signals in the 2.4 GHz band. During lunch hours, increased use of microwaves in the break room can lead to intermittent Wi-Fi connectivity due to this interference.
