Ubuntu
使用 Ubuntu 命令連接到非加密無線網路
我無法使用 Ubuntu 命令行連接到開放的 ie 非加密無線網路。這就是我所做的。我首先關閉網路管理器,然後打開 wlan0 並關閉加密,然後指定開放的無線網路並連接到它:
$ sudo /etc/init.d/NetworkManager stop * Stopping network connection manager NetworkManager [ OK ] $ sudo /sbin/ifconfig wlan0 up $ sudo /sbin/iwconfig wlan0 enc off $ sudo iwconfig wlan0 essid "Cavalier High-Speed 8-4-CAVTEL" $ sudo dhclient wlan0 There is already a pid file /var/run/dhclient.pid with pid 10812 killed old client process, removed PID file Internet Systems Consortium DHCP Client V3.1.1 Copyright 2004-2008 Internet Systems Consortium.

我想知道問題是什麼,我該如何做對?
感謝致敬!
的輸出
/sbin/iwconfig wlan0
顯示您沒有與任何 AP 關聯。您需要
/sbin/iwlist wlan0 scan
搜尋附近的 AP,之前和根據我的經驗,有時之後,您設置/sbin/iwconfig wlan0 essid "essid"
同樣,該應用程序
wicd
非常適合管理您的無線網路,而無需大量額外功能。
