![在 Ubuntu 14.10 上连接到互联网](https://linux22.com/image/979303/%E5%9C%A8%20Ubuntu%2014.10%20%E4%B8%8A%E8%BF%9E%E6%8E%A5%E5%88%B0%E4%BA%92%E8%81%94%E7%BD%91.png)
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。
