The correct answer is C. Change the channel. The best action for a technician to resolve slow and dropping Wi-Fi connections after replacing a WAP is to change the wireless channel. This mitigates interference from other wireless devices or networks operating on the same frequency, which commonly causes performance issues.

Why each option

The best action for a technician to resolve slow and dropping Wi-Fi connections after replacing a WAP is to change the wireless channel. This mitigates interference from other wireless devices or networks operating on the same frequency, which commonly causes performance issues.

AChange the WAP password.

Changing the WAP password affects who can connect but does not address slow speeds or dropping connections for authenticated users.

BChange the encryption type.

Changing the encryption type (e.g., from WPA2 to WPA3) enhances security but typically does not resolve issues related to slow speeds or dropped connections caused by interference.

CChange the channel.Correct

When Wi-Fi connections are slow and dropping, especially after a WAP replacement, it often indicates interference from other nearby wireless networks or devices operating on the same frequency channel. Changing the channel on the WAP to a less congested one (e.g., 1, 6, or 11 for 2.4 GHz) can significantly reduce interference, improving signal quality and connection stability.

DChange the SSID.

Changing the SSID (network name) would require users to reconnect, but it does not resolve underlying performance issues like interference that cause slow speeds and drops.
