Wireless 4965 centos5.4 wireless Internet access

Reference http://pub.itpub.net/post/2102/496647/

 

Centos 5.4 x86_64 t61 wireless network card model is 4965

1. Check whether the kernel supports

Check the configuration file. config

[Root @ ljh ~] # Grep config_iwl4965/reboot/config-2.6.18-164.11.1.el5
Config_iwl4965 = y

2. Check whether there are corresponding modules.

On the Internet, I found that the module corresponding to 4965 is iwl4965, and the actual module is iwlagn. This is true for centos5.3 and ubuntu9 and 04. (This really took me a long time)

[Root @ ljh ~] # Lsmod | grep IW
Iwlagn 134361 0
Iwlcore 131397 1 iwlagn
Mac80211 183113 2 iwlagn, iwlcore
Listen 80211 63825 3 iwlagn, iwlcore, mac80211

;};/Sbin/modprobe-r -- ignore-Remove snd-hda-intel
Alias USB-controller EHCI-HCD
Alias usb-controller1 uhci-HCD
Alias wlan0 iwlagn

The iwlagn module is displayed.

Okay, the module has enabled the NIC.

# Ifconfig wlan0 Up Error
