Ubuntu server 配置 TL-WN821N 无线网卡

公司的服务器安装了ubuntu server 12.04 后有时候拷贝文件会卡住.,怀疑是主板网卡问题.

所以买了一张PCI的网卡后无法驱动,再换无线USB网卡.

选配了TL-WN821N 这款.

弄了一下配置后成功上网.

把配置分析给大家.

root@lejin:/home/yuanwei# vim /etc/network/interfaces

auto lo

iface lo inet loopback

auto wlan0

iface wlan0 inet static

address 192.168.1.18

gateway 192.168.1.1

netmask 255.255.255.0

network 192.168.1.0

broadcast 192.168.1.255

wpa-driver wext

wpa-ssid LovDream_public

wpa-ap-scan 1

wpa-proto RSN

wpa-pairwise CCMP

wpa-group CCMP

wpa-key-mgmt WPA-PSK

wpa-psk da7f876751e3762b82da361c4c4311e507cfb3e014605f160dcf1b86f790574f

其中

wpa-psk da7f876751e3762b82da361c4c4311e507cfb3e014605f160dcf1b86f790574f 生成方法如下:

wpa_passphrase ssid password

vim /etc/wpa_supplicant.conf

ctrl_interface=/var/run/wpa_supplicant

ctrl_interface_group=0

ap_scan=1

network={

ssid="LovDream_public"

pairwise=CCMP TKIP

group=CCMP TKIP WEP104 WEP40

proto=WPA

key_mgmt=WPA-PSK

priority=1

psk=da7f876751e3762b82da361c4c4311e507cfb3e014605f160dcf1b86f790574f

}

可能有些配置重复了. 等后面再修改.

修改后重启服务

root@lejin:/etc/network# /etc/init.d/networking restart

* Running /etc/init.d/networking restart is deprecated because it may not enable again some interfaces

* Reconfiguring network interfaces... ioctl[SIOCSIWENCODEEXT]: Invalid argument

RTNETLINK answers: File exists

报错. 那重启服务器.后OK了.
