Correct answer: radar, rogue AP.
Why this is the answer
Radar systems operate in frequency bands that can overlap with Wi-Fi frequencies, particularly in the 5 GHz band, causing significant interference. This is why Dynamic Frequency Selection (DFS) is used in Wi-Fi to avoid radar signals. Rogue Access Points (APs) are unauthorized APs on a network that can operate on the same channels as legitimate APs, leading to co-channel interference, reduced throughput, and signal degradation. LED lights, while they can generate some electromagnetic interference, are generally not a significant source of RF interference for Wi-Fi in the same way radar or rogue APs are. Fire alarms and conventional ovens do not typically emit RF signals that interfere with Wi-Fi.
