Which internet connection type will most likely experience interference from rain?

CompTIA A+ identifies satellite internet as the connection type most susceptible to weather-related interference, particularly rain, snow, and heavy cloud cover. This phenomenon is known as rain fade. Satellite connections rely on high-frequency microwave signals transmitted between a dish antenna at the customer site and an orbiting satellite. Moisture in the atmosphere absorbs and scatters these signals, causing latency spikes, reduced bandwidth, or complete signal loss during storms.

Fiber (A) uses light signals through glass fiber and is immune to electromagnetic and weather interference. Cable internet (B) uses shielded coaxial lines buried or run overhead, but rain does not affect signal quality in normal conditions. DSL (D) uses telephone lines, which may degrade with physical line issues, but not directly due to rain in the same way satellite is affected.

Thus, satellite internet is most likely to experience signal degradation during rain conditions.
