Match each wireless connectivity issue to its primary cause.

Signal AbsorptionRF energy is absorbed when passing through dense building materials such as concrete or metal walls.
Channel OverlapAccess points operating on adjacent, non-standard frequencies in the 2.4 GHz band cause interference.
Multipath InterferenceRF signals reflect off metallic surfaces, causing multiple identical signals to arrive at the receiver slightly out of phase.
AttenuationRadio signals naturally decrease in strength as distance from the wireless access point increases.

Answer

Signal Absorption matches dense building materials absorbing RF waves; Channel Overlap matches adjacent non-standard 2.4 GHz frequencies; Multipath Interference matches signals reflecting off surfaces arriving out of phase; Attenuation matches signal loss due to distance.

Each wireless symptom maps directly to its fundamental radio frequency propagation behavior: Absorption relates to barrier materials, Channel Overlap relates to frequency assignment, Multipath Interference relates to signal reflection, and Attenuation relates to distance loss.

Step-by-Step Solution

Identify physical barriers reducing signal strength

Dense materials like concrete absorb RF energy (Signal Absorption).

Physical obstacles weaken the signal via absorption.

Analyze frequency channel allocation

Adjacent overlapping channels cause frequency collision and noise (Channel Overlap).

2.4 GHz requires non-overlapping channels (1, 6, 11) to avoid interference.

Examine reflective environment effects

Reflected waves arriving out of phase degrade signal clarity (Multipath Interference).

Bouncing signals distort the primary transmission.

Assess impact of distance from the Access Point

Signal strength weakens over distance (Attenuation).

Free-space path loss naturally reduces RF power as range increases.
