This article introduces the relevant knowledge of "how to configure wireless network card under redhat linux AS4". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Here's how to use madWifi for installation.

1. Download the following four packages:

Madwifi-0.9.3-33_r2088.el4.at.i386.rpm

Madwifi-devel-0.9.3-33_r2088.el4.at.i386.rpm

Madwifi-hal-kmdl-2.6.9-42.0.3.EL-0.9.3-33_r2088.el4.at.i686.rpm

Madwifi-kmdl-2.6.9-42.0.3.EL-0.9.3-33_r2088.el4.at.i686.rpm

The above four are the latest files, please depend on your own computer, if it is a 64-bit cpu computer, please choose the 64 package.

two。 Install the downloaded rpm package

# rpm-I madwifi*rpm (for multiple installations at a time, or individually)

3. Load into the kernel module

# modprobe ath_pci

4. If there is an active wired network card, it is prohibited first.

# ifconfig eth0 down

5. Set up a wireless network card

# iwconfig ath0 essid home (configure SSID to distinguish whether you want to connect to that ap)

# iwconfig ath0 channel 6 (configure the channel for ap)

# iwconfig ath0 key open S 1234 (configure the protocol of ap, as well as password. S: represents ACSII code)

# iwconfig ath0 mode Managed (configure ap mode, which is generally not required)

After the configuration, take a look at the ath0 information should be as follows:

Ath0 IEEE 802.11b ESSID: "home"

Mode:Managed Frequency:2.437 GHz Access Point: Not-Associated

Bit Rate:0 kb/s Tx-Power:31 dBm Sensitivity=0/3

Retry:off RTS thr:off Fragment thr:off

Encryption key:off

Power Management:off

Link Quality=0/94 Signal level=-98 dBm Noise level=-98 dBm

Rx invalid nwid:0 Rx invalid athrypt:0 Rx invalid frag:0

Tx excessive retries:0 Invalid misc:0 Missed beacon:0

6. Activate ath0 wireless network card

# ifconfig ath0 up

7. Dynamic ip selection

# dhclient ath0

Then you can try it and surf the Internet wirelessly!

Settings for boot auto-loading:

1. First modify / etc/modprobe.conf to add

Install ath0 / sbin/modprobe ath_pci; / usr/bin/wlanconfig ath0 create wlandev wifi0 wlanmode sta

Remove ath0 / usr/bin/wlanconfig ath0 destroy; / sbin/modprobe-r ath_pci

Alias ath0 ath_pci

If there is alias wifi0 ath_pci, delete it.

two。 Create an ifcfg-ath0 file under / etc/sysconfig/networking/devices in a format such as:

# Atheros Communications, Inc. AR5005G 802.11abg NIC

DEVICE=ath0

ONBOOT=yes

BOOTPROTO=dhcp

TYPE=wireless

KEY=s:1234

ESSID=home

MODE=Managed

RATE=auto

IWPRIV= "authmode 1" (IWPRIV has two modes: authmode 1 for open,authmode 2 for shared mode, which should be paid special attention to)

(note: if there is a space after the = sign, quotation marks are required.)

If WEP is started, the above KEY is the WEP password, and the first s indicates that the password is the ASCII character.

3. Copy ifcfg-ath0 to / etc/sysconfig/network-scripts and / etc/sysconfig/networking/profiles/default, and delete the ifcfg-wifi0 below it (three places, that is, the above three places).

Restart the machine and the wireless network card loads automatically.
