A company has recently implemented a new Wi-Fi network in their office. Employees are experiencing intermittent connectivity and slow network performance. Investigation shows that the Wi-Fi access points are broadcasting on overlapping channels. Which of the following would be the best course of action to resolve this issue?
You selected this option
Increase the signal strength of all access points to maximize coverage
You selected this option
Change the channels on the access points to non-overlapping settings such as channels 1, 6, and 11
You selected this option
Change all Wi-Fi passwords to restrict network access
You selected this option
Reposition all access points to different locations within the office
Changing the channels on the access points to non-overlapping channels (e.g., channels 1, 6, and 11 in a 2.4 GHz band) will reduce interference among the signals, improving connectivity and performance. Channels 1, 6, and 11 do not overlap with each other in the frequency spectrum in the 2.4 GHz band, thereby minimizing the chance of cross-channel interference. Using other channels or repositioning the APs may not necessarily prevent overlap, depending on the other channels in use and physical characteristics of the office.
