QuestionQ26

Networking

A user can connect their laptop to the internet in the main office. However, when the user places the laptop on top of a motor on the factory floor, there is no internet connectivity. Which of the following is the most likely cause of this issue?

Explanation

Motors generate significant electromagnetic interference (EMI) and radio frequency interference (RFI) that disrupts wireless signals. The dramatic change from working office connectivity to no connectivity when placed directly on a motor strongly points to external interference rather than jitter, power levels, or latency issues.
