Which two conditions indicate a possible hidden node problem?

A hidden node problem occurs when two or more client devices are within range of the AP but cannot hear each other , causing frame collisions that lead to degraded performance.

According to RUCKUS One Online Help – RF Interference and Hidden Node Detection and RUCKUS AI Documentation – Airtime Efficiency Analysis , the symptoms include:

(A) Retransmissions: Frequent retries due to undetected collisions.

(D) Reduced throughput: Effective throughput decreases as airtime is wasted on retransmissions and ACK delays.

The issue is common in high-density or obstructed environments. Enabling RTS/CTS or BeamFlex+ can mitigate it by improving communication coordination.

“Channel changes” occur in interference mitigation, not hidden-node detection; “Excessive roaming” and “Increased Tx power” are unrelated effects.
