Question
A company has multiple WAPs within close proximity to each other to allow users to move about seamlessly through the building with their laptops, without losing any connection. However, this has had the opposite effect, causing any user that is close to two of the access points to constantly reconnect to the wireless network. Which of the following should be changed on all the WAPs to allow this to work as the customer intended?
Options
- AChange the SSID to be unique for each WAP.
- BChange the antenna direction to be unique for each WAP.
- CChange the encryption method to be unique for each WAP.
- DChange the channel to be unique for each WAP.

Explanation
When multiple WAPs in the same area use the same or overlapping Wi-Fi channels, they cause co-channel or adjacent-channel interference. This interference causes devices to experience signal degradation, triggering frequent disconnections and reconnections as the client attempts to find a cleaner signal. Assigning non-overlapping channels to nearby WAPs (e.g., channels 1, 6, and 11 on 2.4 GHz) eliminates this interference and allows seamless roaming. Changing the SSID to be unique per WAP would break seamless roaming-users would have to manually switch SSIDs as they move. Changing antenna direction or encryption per WAP would not resolve channel interference and would disrupt the consistent wireless environment needed for roaming.
