Ann, a technician, installs a wireless router in a network closet in a large office. She then configures
all workstations in various offices on that floor to use the wireless connection. Maximum connection
speed at each workstation is 54 Mbps. Some users complain that their network connection is very
slow. Which of the following is MOST likely the problem?
A.
Workstations were configured with the wrong connection speed on the wireless adapter.
B.
Users with a slow connection are too far away from the wireless router.
C.
Users that cannot connect are configured on the wrong channel.
D.
Wireless network SSID is incorrect.
A wireless router in a network closet would have a hard time connecting properly through walls.
The weaker the signal, the lower the Modulation and Coding Scheme (MCS). In order to use the highest MCS to achieve the maximum data rates the signal must be strong and clear. As you move further form the AP and signal degrades, the MCS shifts down from 64 QAM to 16 QAM to QPSK to BPSK. The closer you are to the AP, the cleaner the RF environment, the faster your connection can go.
