A technician is troubleshooting a wireless connectivity issue in a small office located in a high-rise building. Several AP’s are mounted in this office. The users report that the network connections frequently disconnect and reconnect throughout the day. Which of the following is the MOST likely cause of this issue: A)The AP association time is set too low. B)EIRP needs to be boosted. C)Channel Overlap is occuring. D)The RSSI is misreported.
The MOST likely cause of the wireless connectivity issue in this scenario is C) Channel Overlap.
Channel overlap occurs when multiple access points (APs) in close proximity are using the same or overlapping channels. In a high-rise building with multiple APs, this can be a common issue as the signals from neighboring APs can interfere with each other.
When channel overlap occurs, it can cause disruptions in the wireless connections of the devices, leading to frequent disconnects and reconnects throughout the day.
To resolve this issue, the technician should ensure that the APs are using non-overlapping channels. In the 2.4GHz frequency band, the available non-overlapping channels are 1, 6, and 11. In the 5GHz frequency band, there are more channels available and the technician should select channels that do not overlap with neighboring APs.
It’s worth mentioning that it’s always a good practice to perform a site survey to assess the wireless environment, identify sources of interference, and optimize the placement and configuration of APs.
This can help mitigate channel overlap issues and improve overall wireless performance in the office.
