wlan1 接口从 ifconfig 中消失

wlan1 接口从 ifconfig 中消失

我试图通过编辑在我的 wlan1 卡上创建一个虚拟接口（就像在 Windows 中设置托管网络）/etc/network/interfaces：

auto wlan1:0 
iface wlan1:0 inet static
address 192.168.4.1
netmask 255.255.255.0 
wireless-mode ad-hoc

当失败时我尝试过ap-hotspot：

sudo apt-get install ap-hotspot
cd /tmp && wget http://archive.ubuntu.com/ubuntu/pool/universe/w/wpa/hostapd_1.0-3ubuntu2.1_i386.deb && sudo dpkg -i hostapd*.deb && sudo apt-mark hold hostapd
sudo ap-hotspot configure

这也失败了。之后我安装了默认设置network-manager，我注意到我可以看到周围的 wifi 网络，但无法连接到它们。我尝试重新安装 wlan 驱动程序，但没有任何效果。

我将提供一些关于它在我的系统上如何显示的信息

sudo airmon-ng

此外，这个虚拟 wlan1:0 接口仍然在系统上，不会被删除ifdown

我怎样才能摆脱这个 wlan1:0 接口并使 wlan1 显示和工作？

答案1

您以非常令人困惑的方式呈现了大量信息，但我认为您的问题并不严重。您说您的接口文件包含：

auto wlan1:0
iface wlan1:0 inet static
address 192.168.4.1
netmask 255.255.255.0
wireless-mode ad-hoc

请将其更改为：

auto wlan1
iface wlan1 inet static
address 192.168.4.1
netmask 255.255.255.0

然后重新启动。

如果仍然不起作用，请删除 ap-hotspot 和 network-manager，因为您确实手动安装了它们。
