Statistics Reporting LAN Statistics: section displays the detailed receive and transmit statistics (Bytes, Packets, Errors) of the
LAN (Ethernet) interface. These statistics represent the total amount of data and packets transferred between
devices through the Ethernet interface from either direction.
Both unicast IP traffic (conversations between two hosts using HTTP, SMTP, SSH and other protocols) and
broadcast traffic (while addressing all hosts in a given network range with a single destination IP address) is
accounted.
As long as there is some network traffic being generated or passed through the LAN interface, Received and
Transmitted Bytes and Packets value will continue to increase. The Errors value represents the total
number of transmitted and received packets for which an error occurred.
WLAN Statistics: section displays the detailed receive and transmit statistics (Bytes, Packets, Errors) of the
wireless interface.
These statistics represent the total amount of unicast and broadcast IP data transferred between devices
through the wireless interface from either direction.
As long as there is some network traffic being generated or passed through the wireless interface, Received
and Transmitted Bytes, Packets, and Errors (if any); statistic counters will continue to increase.
WLAN Errors: section displays the counters of 802.11 specific errors which were registered on wireless
interface:
Rx invalid NWID value represents the number of packets received with a different NWID or ESSID
- packets which were destined for another access point. It can help detect configuration problems or
identify the adjacent wireless network existence on the same frequency.
Rx Invalid Crypt value represents the number of transmitted and received packets which were
encrypted with the wrong encryption key and failed the decryption routines. It can be used to detect
invalid wireless security settings.
Rx Invalid Frag value represents the number of packets missed during transmission and reception.
These packets were dropped due to re-assembling failure as some link layer fragments of the packet
were lost.
Tx Excessive Retries value represents the number of packets which failed to be delivered to the
destination. Undelivered packets are retransmitted a number of times before an error occurs.
Missed beacons value represents the number of beacons (management packets sent at regular
intervals by the Access Point) which were missed by the client. This indicates that the client is out of
range.
Other errors value represents the total number of transmitted and received packets that were lost or
discarded for other reasons.
