Chapter 4 Configuring Radio Settings
Configuring the Maximum Data Retries
Configuring the Maximum Data Retries
The maximum data retries setting determines the number of attempts the WMIC makes to send a packet
before giving up and dropping the packet.
The default setting is 32. Beginning in privileged EXEC mode, follow these steps to configure the
maximum data retries:
Use the no form of the command to reset the setting to defaults.
Configuring the Fragmentation Threshold
The fragmentation threshold determines the size at which packets are fragmented (sent as several pieces
instead of as one block). Use a low setting in areas where communication is poor or where there is a great
deal of radio interference.
Note When concatenation is enabled for the 2.4-GHz WMIC, the RTS and fragment thresholds are set to 4000.
Changing them to a lower value may degrade performance. The 4.9-GHz WMIC does not support
concatenation.
The default setting is 2338 bytes. Beginning in privileged EXEC mode, follow these steps to configure
the fragmentation threshold:
Use the no form of the command to reset the setting to defaults.
