我最近在 HP Pavilion 上下载了 Ubuntu 14.10。我尝试通过有线连接连接到互联网，但 Ubuntu 无法识别以太网卡。
当我按照以下说明操作时：

首先，它显示有线连接的“电缆已拔出” - 尽管电缆已连接 - 即使在手动编辑 IPv4 设置后，“保存”按钮仍然关闭。
最好的。

答案1
首先按照以下步骤配置 Wi-Fi：
- 插入您的安装媒体（您的 LiveCD/LiveUSB）
- 打开 LiveCD/LiveUSB。
- 导航至
pool-->main-->b-->b43-fwcutter - 双击该
.deb文件并安装它。 - 重启
然后尝试使用以下命令配置以太网：
sudo apt-get install linux-headers-generic build-essential dkms wget http://ftp.de.debian.org/debian/pool/main/r/r8168/r8168-dkms_8.038.00-1_all.deb sudo dpkg -i r8168*.deb echo "blacklist r8169" | sudo tee -a /etc/modprobe.d/blacklist-r8169.conf sudo modprobe -rfv r8169 sudo modprobe -v r8168 sudo service network-manager restart
您的以太网卡似乎是唯一不受支持的 Realtek 卡。
