If APs are changing channels frequently, it indicates automatic channel selection due to interference. This can cause temporary disconnections as the APs switch frequencies.
Breakdown of Options:
A). Channel interference - # Correct answer. APs change channels automatically to avoid interference, causing disconnections.
B). Roaming misconfiguration - Roaming only affects moving users, but users report issues while stationary.
C). Network congestion - Causes slow speeds, not frequent disconnects.
D). Insufficient wireless coverage - Would cause weak signals, but not channel switching issues.
