wlan1 介面從 ifconfig 中消失

wlan1 介面從 ifconfig 中消失

我試圖透過編輯以下內容在我的 wlan1 卡上建立一個虛擬介面（例如從 Windows 設定託管網路）/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

當失敗時我嘗試過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

那也失敗了。之後我安裝了預設的network-manager，我注意到我可以看到周圍的 wifi 網絡，但無法連接到它們。我嘗試過重新安裝無線區域網路驅動程序，但沒有任何效果。

我將提供一些有關它在我的系統上的外觀的信息

sudo airmon-ng

sudo gedit /etc/udev/rules.d/70-persistent-net.rules

此外，這個虛擬 wlan1:0 介面仍然保留在系統上，不會被刪除ifdown

（請注意，為了清楚起見，我已刪除 eth1 和 lo 配置）。有關介面和驅動程式的更多資訊：

我怎麼能擺脫這個 wlan1:0 介面並使 wlan1 顯示和工作？

答案1

您以非常混亂的方式提供了很多信息，但我認為您的問題並不嚴重。您說您的介面檔案包含：

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

請更改為：

auto wlan1
iface wlan1 inet static
address 192.168.4.1
netmask 255.255.255.0

並重新啟動。

如果仍然不起作用，請刪除 ap-hotspot 和 network-manager，因為您確實手動安裝了它們。
