how should you begin troubleshooting this problem?

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)

Shown is a screenshot of a wireless protocol analyzer displaying the decode information for a single 802.11
encrypted data + CF-Poll frame. The infrastructure BSS on which this information was captured is using
WEP and this particular frame was sent from a client station (STA) to an access point (AP).As a protocol analyst, how would you explain the existence of this frame on the wireless medium given the
information in the decode?
