MTNL 三频有线互联网连接问题

MTNL 三频有线互联网连接问题

我是来自印度孟买的 Ubuntu 用户,订阅了 MTNL 的 Triband 宽带服务。我有一个双启动系统,安装了 Windows 7 和 Ubuntu 12.04。在 Windows 7 上工作时,我的互联网连接良好,但在 Ubuntu 上,尽管菜单中可以看到表示以太网连接正常的“上下箭头”,但我无法访问任何网站或使用终端执行任何 Ubuntu 更新。在 Windows 中,连接是自动的,不需要任何用户名或密码。根据我在这里进行的一些搜索,我找到了一些命令,它们的输出有助于识别问题。我将以下三行的输出发布出来:-

答案1

我在安装 MTNL 数据卡“3G Jadoo”时遇到了问题。我尝试使用 Tata photon。它会自动安装在 Ubuntu 12.10 中。我点击了右上角的网络徽标,然后就可以上网了。
