安装的时候提示缺失固件，但是没有提示缺什么。。正好有线网卡坏了。。
之前Ubuntu跟windows无线网卡都能正常使用。。怎么破Orz
把下面指令 複製 貼進終端機 執行
0. uname -a
- sudo lspci -knn
1-1. 如果無線網卡是 usb 裝置 請增加
sudo lsusb - sudo lshw -numeric -class network
- sudo ifconfig -a
- sudo route -nv
- sudo rfkill list all
- sudo nmcli dev status
把結果直接 選取/複製 貼上來
不要擷圖
若问题缺失无线网卡固件：
先安装 firmware-linux-nonfree
再根据无线网卡厂牌安装对应固件包可解
如：
雷凌 - firmware-ralink
瑞昱 - firmware-realtek
Atheros - firmware-atheros
博通 - firmware-brcm80211, firmware-b43-installer
英特尔 - firmware-iwlwifi, firmware-ipw2x00
从 packages.debian.org/search?suit … s=firmware 下载，用 dpkg -i 手动安装
或连接有线网安装
此时可将固件文件放入U盘，插入机器安装
常用固件 cdimage.debian.org/cdimage/unoff … e/current/
参考 debian.org/releases/stable/ … 04.html.en

在上面下了firmware-brcm80211 (0.43)安装但是还是不行。。
BCM43227 驱动为 b43，Linux 3.17+ 添加支持
也可使用私有驱动 broadcom-sta-dkms
若要使用 b43：
Debian Jessie 内核为 3.16。可从 jessie-backport 安装 4.3 内核 例如 linux-image-4.3.0-0.bpo.1-amd64
用上新内核后，用有线网安装 firmware-b43-installer。这样会自动安装固件
此包不能用另一台机器下载包复制过来安装。无网络安装 b43 固件 参考 help.ubuntu.com/community/WifiD … net_access

sudo apt install apt-file
sudo apt-file update
apt-file search rfkill | grep bin到 packages.debian.org/ 搜索：

==============
顺便提醒一下 你的有线网卡 RTL8101E/RTL8102E j将来如果出现问题，参考以下内容
现在倒是不必折腾。将来万一出了问题留作参考：
forum.ubuntu.org.cn/viewtopic.php?f=116&t=475356
其他网友也有发现 r8169 驱动对 RTL8101/2/6E 的支持不理想：
bugs.launchpad.net/ubuntu/+source/linux/+bug/1132156
该网卡没有内置 EEPROM 可能导致无法固定 MAC 地址，造成问题。参考

bugs.launchpad.net/ubuntu/+source/linux/+bug/1132156/comments/7
realtek.info/pdf/rtl8101e_datasheet_1.2.pdf
或尝试使用 Realtek 官方的 r8101 驱动：(2015-12-08 更新)
realtek.com.tw/Downloads/downloadsView.aspx?Langid=1&PFid=7&Level=5&Conn=4&DownTypeID=3#2
安装 linux-headers-uname -r, build-essential 等必备工具，自行编译

无法找到 firmware-iwlwifi 可能是因为你没有正确启用软件源的 non-free 部分
编辑 /etc/apt/sources.list 在每一行末尾的 ‘main’ 后面添加 ‘contrib non-free’
看起来像这样：
[code]deb Index of /debian jessie main non-free contrib
deb-src Index of /debian jessie main non-free contrib
deb Index of /debian-security jessie/updates main contrib non-free
deb-src Index of /debian-security jessie/updates main contrib non-free
deb Index of /debian jessie-updates main contrib non-free
deb-src Index of /debian jessie-updates main contrib non-free
[/code]
然后执行：
apt update
apt install firmware-iwlwifi 重新启动计算机

其实重新加载 iwl3945 即可
# modprobe -r iwl3945
# modprobe iwl3945不过看起来 iwl3945 一直在寻找属于它的固件
