FreeBSD無線網絡鏈接(WPA/WPA2加密方式)

原文標題：WiFi configuration in FreeBSD (including WPA/WPA2)

 

wireless device is called ndis0

假設無線網卡爲ndis0

 

assume that you are using WPA/WPA2 and DHCP

使用了WPA/WPA2加密方式，而且開啓了DHCP

 

add the following lines into /etc/rc.conf:

wlans_ndis0=」wlan0″
ifconfig_wlan0=」WPA DHCP」

將以上兩行參數，添加到文件/etc/rc.conf

 

assume we have 2 wireless networks for this – 「wifi1」 and 「wifi2」 which have the WPA/WPA2 keys of 「one」 and 「two」 respectively.  We will prefer to connect to 「wifi1」 when possible.

假設咱們有兩個無線網絡，wifi1和wifi2。而且密碼分別爲one和two。優先選擇wifi1。

To setup WPA/WPA, edit (or create) the file /etc/wpa_supplicant.conf and add the following:

network={
priority=1
ssid=」wifi1″
psk=」one」
}

network={
priority=2
ssid=」wifi2″
psk=」two」
}

設置WPA/WPA2。編輯（不存在則新建）/etc/wpa_supplicant.conf文件，添加以上內容到該文件中。

 

Next time you restart your computer, you will have a ‘wlan0’ interface which will attempt to connect to the listed networks (in order of priority).  You can confirm it is associated withifconfig wlan0 – in my case, i get:

wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
ether xx:xx:xx:xx:xx:xx
inet 172.31.0.100 netmask 0xffffff00 broadcast 172.31.0.255
media: IEEE 802.11 Wireless Ethernet autoselect mode 11g
status: associated
ssid wlan1 channel 7 (2442 Mhz 11g) bssid yy:yy:yy:yy:yy:yy
country US authmode WPA2/802.11i privacy OFF txpower 0 bmiss 7
mcastrate 0.5 mgmtrate 0.5 scanvalid 60 protmode CTS roaming MANUAL
bintval 0

下次啓動電腦，wlan0就會嘗試鏈接無線列表中的網絡。可使用ifconfig wlan0命令確認。

Now, although it says 「11g」, it actually achieves 802.11n speeds so you can ignore this.

儘管顯示的是11g類型，但確使用的11n方式的網速，能夠忽略掉。
