Wifi
重啟後Linux Wifi消失了，沒有搜尋wifi網路
我是kali linux的新手，在我安裝linux之後沒有wifi我使用（make unload）和（make load commands）安裝了驅動程序但是沒有wifi可以連接它說沒有網路，每當我重新啟動我的電腦時就沒有wifi，我不知道這是否是正確的安裝方式。重啟後 iwconfig 只給出 eth0 和 lo 沒有無線擴展。我用過
apt-get install firmware-iwlwifi，但它給firmware-iwlwifi is already the newest version (20170823-1) 0 upgraded 0 newly installed, 0 to remove and 0 not upgraded請給我修復，以便我的 wifi 在重新啟動後不會被刪除，wifi 將搜尋並連接到網路。

這個問題解決了我的 apt-get update 沒有工作並且當時給出錯誤我只是通過使用這些命令一一解決了這個問題
# sudo -i # touch /etc/apt/sources.list # chmod 644 /etc/apt/sources.list # echo "deb http://http.kali.org/kali kali-rolling main contrib non-free" > /etc/apt/sources.list # apt-key adv --keyserver hkp://keys.gnupg.net --recv-keys 7D8D0BF6之後我的 apt-get 更新工作，然後我使用這些命令並下載驅動程序並安裝
# git clone https://github.com/mehedishakeel/BroadcomInstaller2017.git然後我在桌面上複製了下載的文件並使用了這些命令
# cd ~/Desktop/BroadcomInstaller2017/ # ls # cat Readme.md # chmod +x Broadcom.sh # ./Broadcom.sh然後它給出 3 個選項選擇 1 個選項，它將安裝 Broadcom 的 wifi 驅動程序。
我不知道這個命令是否適用於其他人，但它適用於我或者還有另一個命令。
# apt-get install linux-image-$(uname -r|sed 's,[^-]*-[^-]*-,,') linux- headers-$(uname -r|sed 's,[^-]*-[^-]*-,,') broadcom-sta-dkms我希望這個命令對其他人有用，現在這個問題已經結束了。
