Percentage of Packets Retransmitted Monitor
The Percentage of Packets Retransmitted monitor displays the percentage of wireless data packet retransmissions experienced by the access point or radio selected in the Network Director View pane.
You can perform the following actions on this line 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 placing the cursor where a vertical grid line bisects a data line.
Ideally, packet retransmission does not exceed 10% of the total number of packets sent. If your retransmission percentage is higher, you can try to lower it by:
- Locating and eliminating noise that could be causing causes spurious packets. For more information on 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. Automatic power tuning will help improve weak signals. For more information, see Understanding Automatic Power Tuning for Wireless Radios.
- Assigning access points to different channels. When channels
are too congested, packet collision and corruption can occur. Enable
automatic channel tuning enabled if it is not already enabled. For
more information, see Understanding Wireless Radio Channels and Understanding Channel Auto-Tuning and Adaptive Channel Planner on Wireless Networks.
Retransmitted packet data is available when you either select a radio or an access point.
