As a WLAN consultant, you have been asked to troubleshoot a problem with a single wireless client station
(Station-Z). Your customer informs you that other wireless client stations are not having problems with
wireless connectivity, and that Station-Z is configured in the same manner as all other wireless client
stations on the network. Station-Z is showing an unusually high retransmission count in its client utility
statistics. Using a wireless protocol analyzer, where and how should you begin troubleshooting this
problem? (Choose 2)
Position the analyzer halfway between Station-Z and the access point. Measure the distance betweenStation-Z and the access point.
Position the analyzer near Station-Z. Analyze Station-Z’s transmissions and acknowledgements. Look
for RF and obstacle-induced interference.
Position the analyzer near the access point. See if Station-Z’s frames are reaching the access point and
if so, analyze their signal strength.
Position the analyzer near Station-Z. Analyze the frames Station-Z is receiving, looking for delayed ACK
Position the analyzer halfway between Station-Z and the access point. Analyze the data rate at which
frames are sent and how long they take to be received.
