Cisco Cisco Aironet 350 Wireless Bridge 정보 가이드
Q. How do I update the software for my Linux client?
A. There are three pieces to the client software:
Radio firmware on the cardThe radio firmware resides on the client device, and in
the case of the PC Card, is actually removed from the PC when the card is removed.

These three pieces of software have different functions, but work together in order to provide
wireless connectivity to your client. They should always be updated to the most recent
versions available. The client driver and the ACU are bundled together on the Linux utilities
page. The firmware is a separate download from the hardware pages for the radio. Refer to
the Release Notes for Cisco Aironet Wireless LAN Adapters and locate the Installation

Q. What distributions and kernels does the Linux client run on?
A. The Linux driver runs on most distributions, and kernels 2.2.x and 2.4.x are supported.
While there is a precompiled driver for RedHat 7.1 that runs kernel 2.4.2−2, the source is
included so that you can compile binaries under any of the supported kernels. You should use
PCMCIA−CS version 3.1.22 or later for 340 series clients, and 3.1.26 or later for 350 series
clients.

Q. When I try to launch the Aironet Client Utility (ACU) from a terminal
window, I get the
window, I get the
No Radio Found
error message. What is the problem?
A. If the driver for the card is not installed properly or not loaded, the ACU cannot find the
card, and displays this error. Re−run the installation script with sh ./cwinstall from the
directory where you unzipped the AIROLINUXvxxxxx.tar.gz file.

directory where you unzipped the AIROLINUXvxxxxx.tar.gz file.
Q. When I try to compile the driver from the PCMCIA−CS directory, I get
memcpy
errors. Where do I look to find the problem?
A. This can come from a number of sources, but most commonly, it is a problem with either
of these sources:
of these sources:
The PCMCIA−CS source
♦
Your kernel source
♦
Make sure that the PCMCIA−CS source is at least 3.1.22 (3.1.26 or later is preferred). Also,
verify that the running kernel and your kernel source tree are the same.

Q. I use a PCI card, and the readme.txt file says I should configure
linuxconf in order to load the module airo.o for the PCI card, but if I do it,
it gives me an error that the module cannot be found. What is the
problem?
