A network engineer is troubleshooting wireless performance issues in a multi-story office building. Wireless site survey logs indicate that client devices in crowded conference rooms remain stickily connected to distant access points (APs) with a weak RSSI of -83 dBm, causing slow throughput and dropped VoIP calls. Simultaneously, the 2.4 GHz spectrum is severely saturated with high client density. Which of the following actions should the engineer take to resolve these wireless connectivity and coverage issues? (Select TWO.)
- Configure band steering on the wireless LAN controller to push dual-band client devices onto the 5 GHz spectrum.Answer
- Adjust the minimum RSSI disassociation threshold on access points to disconnect clients when signal strength drops below a playable level.Answer
- CIncrease the transmit power on all 2.4 GHz access point radios to maximum to overpower adjacent client traffic.
- DEnable 160 MHz channel bonding across all 5 GHz access points to increase radio signal penetration through physical walls.
Answer
The correct actions are to enable band steering on the wireless controller to steer clients away from the saturated 2.4 GHz spectrum onto 5 GHz, and to adjust minimum RSSI thresholds on access points to resolve sticky client issues by forcing weak clients to disassociate and roam.
Enabling band steering optimizes traffic by directing dual-band clients away from the congested 2.4 GHz frequency and onto 5 GHz channels. Configuring minimum RSSI thresholds fixes sticky client roaming by actively disassociating client devices when their signal drops below a specific dBm level, prompting them to scan and connect to an AP with better RSSI.
