As a WLAN consultant, you have been contacted by one of your customers to go to their premises 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 utilities. Using a wireless protocol analyzer, where and how would you begin troubleshooting this problem?

A.
Position the analyzer half way between Station-Z and the access point. Analyze the distance between Station-Z and the access point.

B.
Position the analyzer near Station-Z. Analyze Station-Z’s transmissions and acknowledgements. Look for RF and obstacle-induced interference.

C.
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.

D.
Position the analyzer near Station-Z. Analyze the frames Station-Z is receiving, looking for corrupted data frames.

E.
Position the analyzer half way between Station-Z and the access point. Analyze the data rate at which frames are sent and how long they take to be received.
