如何将 Ubuntu 连接到大学局域网(Windows,动态 IP)以使用互联网

我最近从 Windows 切换到 Ubuntu,所以对此不太了解。问题是我无法通过 LAN 电缆将我的 Ubuntu 笔记本电脑连接到我大学的计算机实验室,以便使用互联网。

当我在笔记本电脑上安装 Windows 时,我会去实验室并将网线插入笔记本电脑的插座。然后我会禁用本地连接,然后启用它。我必须禁用它,因为在我的大学里,计算机科学系为所有其他系提供互联网,并且它有多个网络名称,例如网络 24、网络 26 等。

因此,每次我禁用并重新启用本地连接时,它都会将我的 Windows 笔记本电脑连接到随机网络并打开互联网。

其次,实验室中的 PC 具有特定的 IP 地址,例如 192.168.1.253。但我不需要在本地连接的属性中输入任何 IP 地址或子网掩码或任何其他内容。我只需将设置设为“自动获取 IP 地址”,然后禁用本地连接,然后再启用它。

现在我已经在笔记本电脑上安装了 Ubuntu 12.10,但无法将笔记本电脑连接到大学网络以使用互联网。我将 Ubuntu 有线连接 IPV4 设置设置为“自动 DHCP”,但它无法将我连接到互联网。

现在请不要告诉我去询问实验室管理员,因为他只知道如何打开 Youtube :) 也不要告诉我切换回 Windows,因为我讨厌病毒。

请帮我解决这个问题。我需要它,因为大学已经获得了一些在线订阅,以便学生可以访问期刊进行研究工作。我将不胜感激您的帮助。

PS:以下是代码结果......
