Jea*_*nno 15 wireless networking ethernet
自从我安装了 12.04（全新安装而不是升级）以来，我的 Internet 连接一直在下降。连接中断可能持续 15 秒到大约 3 分钟，然后连接恢复。这种行为发生在我主动浏览 Internet 时，或者当我唤醒计算机并打开 Firefox（有时我有连接，有时没有）时。请注意，当 Internet 连接打开时，速度并不慢（如 speedtest.net 的结果所示）。
一开始以为是我的RTL8111/8168B网卡的驱动r8169有问题，于是从Realtek官网下载了r8168，按照详细说明（把r8169列入黑名单，改文件为.bsh...），但还是同样的问题仍然存在。
所以我切换到无线连接，我遇到了同样的问题，互联网连接随机掉线。
有任何想法吗？提前致谢。

请注意，我的无线网卡没有显示，我有 Ralink 3390 卡（由于某种原因，它显然没有显示在 Ubuntu 上），但是我能够连接到无线网络并连接到 Internet（当它工作时）。
尝试从网络管理器中删除连接并创建一个新连接。（如果您使用 LAN 卡连接或尝试无线，请尝试 DSL）。它可以工作。我不是 Ubuntu 专家，我不确定这是否可行。我是一个新用户，我之所以这么说是因为它对我有用。希望这可以帮助。
因为您使用 Ubuntu，所以您可以从 Debian 存储库安装 Ralink 固件。为此，请按照以下步骤操作：
/etc/apt/sources.list： deb http://ftp.us.debian.org/debian wheezy main contrib non-free # Ralink 的 Debian 存储库
sudo apt-get 更新 && sudo apt-get 安装固件-ralink
我希望这能解决问题。（在我的案例中有效。）

我的笔记本电脑上有相同的以太网卡。我在 11.10 上也遇到同样的问题，博客解释说 RTL8111/8168B 与 Linux 内核中的驱动程序会出现连接问题。本博客中文撰写： 来自linux deepin官方博客
建议您可以从Realtek下载官方驱动程序：http://www.realtek.com.tw/downloads/downloadsView.aspx ?Langid=3&PNid=13&PFid=5&Level=5&Conn=4&DownTypeID=3&GetDown=false
或者直接在这里下载：点击这里
请参阅自述文件并使用“sudo”安装它。希望对你有帮助。
