Cisco Cisco Aironet 350 Wireless Bridge 信息指南
A. While the name of the module is actually airo.o, linuxconf looks for just airo and looks
for a file that ends with .o in the modules directory. Make sure that the airo.o file resides in
your modules directory. If it does not, go to your PCMCIA−CS directory and re−run the
make config, make all and make install procedures as directed in the ./cwinstall script.

Q. How do I make a Client Card work with a non−Cisco access point?
A. The access point, not the client, controls interoperability. Make sure that the access point
does not use any proprietary extensions or requires firmware specific to the manufacturer
products. Also make sure that the access point is 802.11b compliant.

Q. The access point has an entry in the association table for my PCMCIA
card, but I cannot get a dynamic IP address. What is the problem?
card, but I cannot get a dynamic IP address. What is the problem?
A. The most common cause of this behavior is the inability of the PC to communicate with
the card through the PCMCIA socket. Check the driver for your PC Card Socket. If it is a
CardBus driver, it is most likely 32−bit only. The Cisco Aironet card requires 16−bit access,
and if the modules for the socket are compiled for 32−bit mode only, you must recompile
them into 16−bit capable versions. Check lsmod in order to verify that the airo and
pcmcia_core modules are loaded.

Q. When my PC card is passing traffic, the speakers in my laptop buzz.
What is the problem?
What is the problem?
A. This problem comes from inadequate shielding around the PCMCIA socket itself. The
radio energy of the card passing traffic leaks over into the speakers, since it is not sufficiently
contained in the card socket, and presents itself as a buzz in the speakers. Your card is passing
traffic. It is not a problem with the card; it is the socket. Resolution needs to come from the
manufacturer of the laptop who chose not to shield the socket.

Q. Where can I find help to install my Client Card?
A. Refer to Cisco Aironet Wireless LAN Adapters Installation and Configuration Guide for
Linux.

Q. Can I remove the PCMCIA card radio module from an Aironet PCI
client adapter and use it as a PCMCIA client adapter?
client adapter and use it as a PCMCIA client adapter?
A. No. This is not supported in any version of the hardware. Because the radio card is set to a
different I/O mode, the card is not recognized by the Operating System. There is no known
way to bypass this.

Q. What are possible sources of interference for the Radio Frequency
link of my Client Card?
link of my Client Card?
A. Interference can come from a number of sources, which includes 2.4 GHz cordless phones,
improperly shielded microwave ovens, and wireless equipment manufactured by other
companies. Police radar, electrical motors and moving metal parts of machinery can cause
interference, too. Refer to Troubleshooting Problems Affecting Radio Frequency
Communication for more information.
