Troubleshooting Wireless Connectivity Issues in a High-Rise Office

B.

The most likely cause of the wireless connectivity issue in the small office located in a high-rise building where users report frequent disconnections and reconnections throughout the day is channel overlap.

Channel overlap occurs when multiple access points (APs) in close proximity use the same or overlapping wireless channels. This can cause interference and result in poor wireless performance, including dropped connections.

To troubleshoot this issue, the technician should perform a wireless site survey to identify the wireless channels in use and check for channel overlap. If channel overlap is detected, the technician should reconfigure the APs to use non-overlapping channels, adjust the AP transmit power levels to reduce interference, or add additional APs to distribute the load across more channels.

The other options provided are less likely to cause this issue.

• The AP association time being set too low may cause disconnections if a client device fails to re-associate in time, but this is less likely to occur frequently throughout the day for all users.
• EIRP (Effective Isotropic Radiated Power) refers to the strength of the radio signal transmitted by an AP and boosting it may improve coverage but is less likely to cause frequent disconnections.
• RSSI (Received Signal Strength Indicator) is a measure of the strength of the signal received by the client device and misreporting it may affect performance, but again it is less likely to cause frequent disconnections for all users.
