RUCKUS indoor Access Points usestatus LEDsto communicate key operational states during deployment and runtime. The LEDs provide immediate visual feedback about the AP’s connectivity, power condition, and client activity.

According to theRUCKUS One Online Help – Access Point LED Indicators, and verified in theRUCKUS AI documentation, the LEDs typically display the following primary states:

Controller Connected (A):Confirms that the AP has successfully registered and established a control session with the RUCKUS controller or RUCKUS Cloud instance.

Insufficient PoE Power (C):Indicates that the AP is receiving inadequate power, such as being powered through 802.3af instead of 802.3at, which may disable high-power features or additional radios.

Clients Connected to a Radio (D):Lights up when one or more clients are associated with the AP’s wireless radios, signifying active WLAN operation.

Other listed options—USB dongle inserted,data plane tunnel connected, androutable IP assigned—are not standard LED indications across RUCKUS indoor AP models. They may represent system events but not physical LED states.

InSmartZone, WLAN Groups define which SSIDs (WLANs) are broadcast by specific APs or AP Groups. However, for an AP Group to actually broadcast the WLANs from a WLAN Group, that WLAN Group must be explicitlyassigned to the AP Group’s radio interfaces(2.4 GHz, 5 GHz, or 6 GHz).

According toRUCKUS One Online Help – WLAN Group ConfigurationandSmartZone Administrator Guide, when an AP Group does not have a WLAN Group bound to its radios, the SSIDs in that group will not be broadcast—even if both exist within the same Zone.

Creating the WLAN Group at the Domain level or Zone level is valid, but broadcasting depends on association at the AP Group radio level.

Band Steeringis a RUCKUS feature designed to guide dual-band capable clients toward the5 GHz band, which generally provides better performance and less interference than 2.4 GHz.

As described inRUCKUS One Online Help – Band Steering ConfigurationandRUCKUS AI Documentation – Client Connectivity Optimization, when a client attempts to connect, the AP temporarily delays responses to 2.4 GHz probes, encouraging the client to associate on 5 GHz.

This feature enhances airtime efficiency and reduces congestion in dense environments.Band Balancingdistributes clients between APs, whileSmartCastandChannelFlymanage QoS and channel optimization, respectively.

When two access points operate onoverlapping channelsin the same frequency band—such aschannel 7 and channel 8in the 2.4 GHz range—they createAdjacent Channel Interference (ACI). Unlikeco-channel interference (CCI), which occurs when APs share the exact same channel,ACIresults from partial channel overlap that causes energy spillover between adjacent frequencies.

According toRUCKUS One Online Help – Radio Configuration and Channel Planning, adjacent channels in 2.4 GHz are only 5 MHz apart, while each Wi-Fi channel occupies 20–22 MHz of bandwidth. As a result, channels like 7 and 8 significantly overlap, creating degraded performance, retransmissions, and reduced throughput.

RUCKUS’sChannelFlytechnology in bothRUCKUS AIandRUCKUS Analyticshelps automatically select non-overlapping channels (such as 1, 6, and 11) to minimize ACI and optimize network capacity.

Therefore, the correct answer isA – Adjacent interference, which directly applies to overlapping channel configurations.
