Telxon/Aironet Radio 2.4 GHz Firmware Issues Disconnects
Telxon/Aironet Radio 2.4GHz Firmware Issues Disconnects
Introduction
The following describes issues with Telxon/Aironet Radio firmware issues and terminal
disconnects.
Problem Description
Access points fill up with CRC errors and lock up. This happens particularly with version 1.24
Radio firmware in the terminals that roam between cells.
Also, terminals do not function in CAM mode and will disconnect randomly.
Resolution
Firmware in the 4800 AP's needs to be at least version 3.92.
Terminals will not work in CAM mode. The terminals radio firmware must be at least 3.65 with the
following file for the radio settings: http://www.connectrf.com/Documents/Pktds8.def

Recommended CFG24 Settings for Symbol Radios
Recommended CFG24 Settings for Symbol Radios
Introduction
The following describes the recommended CFG24 settings for Symbol radios.
Problem Description
If not set properly, these settings will override Twin Client options. This effects how the Twin
Client operates for the user, and in some cases, it appears that the Twin Client features do not
work.
Resolution
Set CFG24 as follows:
Net ID:
SubNet Mask:
Default Router:
MU IP Address:
Diversity:
MU Sleep Mode:
Boot Mode:
Pwr Management:
Buffers:
ReXmit Delay:
Rate Control:

Techniques for Configuring Radio Configuration Parameters in Terminals
Techniques for Configuring Radio Configuration Parameters in
Terminals
Introduction
The following describes techniques for configuring radio configuration parameters in terminals.
This should be done prior to loading Twin Client.
Problem Description
While 802.11b is a standard, all of the manufacturers implement it differently, leaving the end
user responsible for configuring the parameters correctly between terminal and access points.
Resolution
Obtain the assistance and software from either the radio manufacturer or the Access point
manufacturer.
We currently know the following methods:
Radio Manufacturer
Symbol Spectrum 24
Technique
Use the manufacturers programs LWP
and UDP
Lucent/WaveLan
Edit the configuration files found within
the Lucent directory for the specific
terminal.
Edit the configuration files found within
the Cisco/Aironet directory for the specific
terminal. Rumor has it that there exists a
client program called ACU.

Symbol S24 Radios, Flash Hardware Not Backward Compatible
Symbol S24 Radios, Flash Hardware Not Backward Compatible
Introduction
Symbol current radios and flash hardware are not backward compatible, and render WHAP
obsolete.
The symptoms are as follows:
1. The terminal exits to a B: prompt.
2. The terminal is very slow after loading WHAP.
3. High data rate terminals are in a loop when using LWP4.07 from Symbol.
Problem Description
Symbol current radios and flash hardware are not backward compatible. The Access Points and
terminals must have the correct Symbol drivers loaded to match the radios and flash hardware.
Symbol current drivers for the terminals can be found at:
http://www.symbol.com/services/downloads/download_spec24.html
Access Point software can be found at:
http://www.symbol.com/services/downloads/spec24_firmware2.html
http://www.symbol.com/services/downloads/spec24_firmware_2_2.html
http://www.symbol.com/services/downloads/download_wireless.html
http://www.symbol.com/services/downloads/spec1_2.html
http://www.symbol.com/services/downloads/download_wireless_software_8021.html
Symbol LWP and UPD802 drivers for the terminals can be found at:
http://www.symbol.com/services/downloads/download_mobile_series3000.html
Resolution
Following Symbol’s direction for identifying the affected hardware, obtain the correct drivers from
Symbol and load the terminals and Access Points appropriately.
Then obtain the current release of Twin Client from our web site: http://www.connectrf.com.
WHAP is obsolete.
