A customer has recently implemented a new wireless infrastructure using WLC-5520 at a site directly next to a large commercial airport. Users report that they intermittently lose WI-FI connectivity, and troubleshooting reveals it is due to frequent channel changes. Which two actions fix this issue? (Choose two)
Correct Answer: A,E
To fix the issue of intermittent Wi-Fi connectivity due to frequent channel changes near a large commercial airport, the actions that should be taken are to remove UNII-2 and Extended UNII-2 channels from the 5 GHz channel list (Option A) and disable DFS channels (Option E). These channels are more susceptible to interference from radar systems used in aviation, and disabling them can reduce the occurrence of automatic channel switching that leads to connectivity loss.
