![wlan1 接口从 ifconfig 中消失](https://linux22.com/image/1125092/wlan1%20%E6%8E%A5%E5%8F%A3%E4%BB%8E%20ifconfig%20%E4%B8%AD%E6%B6%88%E5%A4%B1.png)
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。
