我无法在 Linux (Mint) 上连接到 WEP wifi:我没有 DHCP 提供。
我的 bash 脚本(我以 root 身份启动)执行以下操作:
pkill dhclient
pkill wpa_supplicant #just in case
ip link set dev wlan0 down
ip addr flush dev wlan0
iwconfig wlan0 essid "MyWifi"
iwconfig wlan0 enc off
ip link set dev wlan0 up
dhclient -v wlan0
当我启动它时,我没有收到 DHCP 提议:

重要:
- 我没有 NetworkManager(没有运行和删除 -我看到这是一个常见问题),我更喜欢使用命令行。
当我扫描我的 wifi 时,我认为没问题:

我知道 wifi 可以工作,因为我有其他设备连接到它
我知道我的 wifi 加密狗也可以工作,因为我设法连接到其他 wifi (WPA)。
