AP-11 and AP-12 were designed on non-overlapping channels. A technician mistakenly sets AP-12 to AP-11’s channel, and staff report slow performance near both. What should the technician do first?
Select an answer to reveal the explanation.
Short Explanation
Same channel on neighbor APs is co-channel interference—classic self-inflicted wound. Put AP-12 back on the design channel and the air calms down. Cranking power just makes the argument louder.
Full Explanation
Deviating from designed channels can place neighboring APs on the same channel, producing co-channel interference (CCI) and degraded performance. The technician’s correction is to restore the design channel assignment rather than raising power or weakening security. Following the channel plan is a core install-from-design skill.
