A network administrator redesigned the positioning of the APs to create adjacent areas of wireless coverage.
After project validation, some users still report poor connectivity when their devices maintain an association to a
distanced AP. Which of the following should the network administrator check FIRST?


A. Validate the roaming settings on the APs and WLAN clients
B. Verify that the AP antenna type is correct for the new layout
C. Check to see if MU-MIMO was properly activated on the APs
D. Deactivate the 2.4GHz band on the APS
