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

报错. 那重启服务器.后OK了.
