802.11 Packet Errors Monitor
The 802.11 Packet Errors monitor displays the number of packet errors experienced by the object selected in the View pane. The object is polled and plotted at the standard polling rate.
You can perform the following actions on this graph:
- Change the time period over which to display the percentage of retransmitted packets by selecting a time period from the list in the upper right corner.
- Display a numeric value by mousing the cursor where a vertical grid line bisects a data line.
Packet error data is available when you select a radio, an access point, a floor, a building, or a site in any view. Radios and access points are displayed automatically in the View pane—you must configure floors, buildings, and sites. See Creating a Site, Configuring Buildings, and Configuring Floors for details.
If your packet error rate is too high, you can try to lower it by:
- Locating and eliminating noise that could be causing causes spurious packets. For more information about noise, see Monitoring RF Interference Sources on Wireless Devices, Monitoring RF Interference Sources on One Radio, and Monitoring RF Interference Sources For Radios on One Access Point.
- Checking for weak signals. If automatic power tuning is not enabled, try enabling it. For more information, see Understanding Auto Tune Power Policy for Wireless Radios.
- Assigning access points to different channels. When channels are too congested, packet collision and corruption can occur. If automatic channel tuning is not enabled, try enabling it. For more information, see Understanding Wireless Radio Channels and Understanding Adaptive Channel Planner.
