what possible first step do you take toward troubleshooting ABC Company’s wireless network problem?
ABC Company is a small company that has hired you to troubleshoot an intermittent performance problem with their ERP WLAN. They have noticed that intermittently throughout a typical day, their WLAN’s latency increases enough to interrupt some mission critical applications. Considering that ABC Company has no baseline analysis, what possible first step do you take toward troubleshooting ABC Company’s wireless network problem?
what happens to the STA’s DCF contention window?
An HR-DSSS STA does not receive an ACK for a first-attempt data frame that it transmitted. In this case, what happens to the STA’s DCF contention window?
Which statements are true regarding the acknowledgement procedures in an IEEE 802.11 WLAN?
A station has successful received a frame. Which statements are true regarding the acknowledgement procedures in an IEEE 802.11 WLAN?
What is the size of this IEEE 802.11 MPDU?
Given: An IEEE 802.11 data frame is encrypted with CCMP/AES and is carrying the maximum frame payload. This data frame is being transmitted from a QoS STA to a QoS AP.
What is the size of this IEEE 802.11 MPDU?
where and how would you begin troubleshooting this problem?
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?
