Figure 23 Station Mode: Link Info: Trend Chart

The following table describes the labels in this screen.

Authentication This field displays the authentication method of the AG-220.

Network Mode This field displays the wireless standard (A, B or G) of the AP or peer computer.

Total Transmit This field displays the total number of data frames transmitted.

Total Receive This field displays the total number of data frames received.

Link Quality This field displays the signal strength of the AG-220.

Trend Chart Click this button to display the real-time statistics of the data rate in kilobits per

second (Kbps).

Signal Strength The status bar shows the strength of the signal. The signal strength mainly

depends on the antenna output power and the distance between your AG-220 and

the AP or peer computer.

Link Quality The status bar shows the quality of wireless connection. This refers to the

percentage of packets transmitted successfully. If there are too many wireless

stations in a wireless network, collisions may occur which could result in a loss of

messages even though you have high signal strength.
