Why each option

Duplicate IP address issues on a wireless network typically indicate a conflict between DHCP servers attempting to assign addresses to the same subnet.

AAdd another wireless access point.

Adding another wireless access point would extend Wi-Fi coverage but would not resolve duplicate IP address issues caused by misconfigured or conflicting DHCP services.

BAdd another DHCP server.

Adding another DHCP server without proper configuration, such as defining exclusions or implementing split scopes, would likely exacerbate the problem by introducing another source of potential IP address conflicts.

CDisable the wireless DHCP server.Correct

Disabling the DHCP server on the wireless router or access point (AP) would resolve duplicate IP address issues if there is already a primary DHCP server on the corporate network. When two or more DHCP servers assign addresses on the same subnet without proper coordination, they can hand out the same IP address, leading to network conflicts.

DChange the default gateway of the wireless router.

Changing the default gateway of the wireless router would affect network routing for clients but would not prevent duplicate IP addresses from being assigned by conflicting DHCP services.
