CompTIA Network+ N10-009 Practice Question

The observed fluctuations in signal strength depicted by the Wi-Fi analyzer are most likely due to interference. Interference can be caused by numerous factors such as other wireless signals, electronic devices, or even physical barriers that disrupt or weaken the wireless signal. Choosing a less crowded channel or relocating the wireless access points can often reduce such interference. Incorrect answers include 'Faulty network card,' which would likely cause persistent, not fluctuating issues, and 'Inactive wireless SSID,' which would result in no connectivity rather than fluctuating signals. 'Exceeding bandwidth capacity' causes slow performance but does not cause signal strength fluctuations.
