当我尝试运行iwconfig或ifconfig找不到该命令时。如何安装wifi驱动程序？
我已经安装了( iwlwifi-6000g2a-ucode-18.168.6.1.tgz)这里。当我提取时，我得到了它（iwlwifi-6000g2a-6.ucode）。我和它有什么关系？

答案1
这firmware-iwlwifi是一个非自由软件。
您需要添加non-free到您的sources.list.看示例sources.list
sudo sed -i 's/main/& contrib non-free/' /etc/apt/sources.list
sudo apt update
sudo apt install firmware-iwlwifi
sudo /usr/sbin/modprobe -rv iwlwifi
sudo /usr/sbin/modprobe -v iwlwifi
ifconfig要解决and 的命令未找到错误iwconfig，您需要安装wireless-toolsand net-tools：
sudo apt install wireless-tools net-tools
使用/sbin/iwconfigand/sbin/ifconfig因为/sbin你的根中缺少PATH。
