Belkin 无线 802.11g USB 网络适配器无法工作

Belkin 无线 802.11g USB 网络适配器无法工作

大家好,我对 Ubuntu 还很陌生。我现在在同一台电脑上运行最新的 Ubuntu 和 Windows。无线连接在 Windows 上工作正常,但在 Ubuntu 上连接和断开连接。

我使用带有无线路由器(Belkin 和 Belkin 无线网络适配器)的 ADSL。

答案1

我们需要更多信息才能帮助您。例如您使用的是什么类型的无线适配器以及您使用的 Ubuntu 版本。

------尝试 1:失败

一个通用提示是系统->管理->硬件驱动程序。也许您需要下载一些驱动程序。如果您的无线网卡在打开的窗口中列出,请单击按钮安装其驱动程序。

但由于信息太少,这只是盲目尝试。

------尝试 2:失败

感谢您提供的所有信息。Belkin 以在同一产品中使用不同的芯片组而闻名,F5D7050 至少使用 3 种不同的芯片组。无论如何,windows 的驱动程序文件名是黄金。您的卡可能是 rt2500。

此卡最常见的问题是多个模块(类似 Windows 驱动程序)尝试使用它,从而产生冲突。您需要进行一些文件编辑操作来解决它。

按 ALT+F2 或打开控制台。输入或复制/粘贴:

gksudo gedit /etc/modprobe.d/blacklist.conf 

现在在文件末尾附加这两行:

blacklist rt2500usb
blacklist rt2800usb

然后重启,如果幸运的话,重启后它应该可以正常工作。如果没有,则可能存在其他类型的冲突,请再次编辑文件,删除行,重启,打开控制台并输入:

dmesg | grep rt

似乎没有加载任何 rt* 模块。所以这是我的错误。但如果 wifi 工作正常(有时),它必须加载一些驱动程序,而 Windows 驱动程序使它看起来像 rt2500...

----------- 尝试 3:从未测试过

再试一次。有报道称,使用 rt* 芯片组和当前内核的人会出现断线的情况。您可以尝试更新内核。

您需要添加此 PPA添加到您的软件源中。在 PPA 页面中,您可以找到有关如何添加它们的详细说明,但简而言之,您必须打开系统->管理->软件源,单击“其他软件”选项卡,单击添加并在那里写入ppa:内核 ppa/ppa

之后你需要安装更新的内核。最简单的方法是打开 Ubuntu 软件中心,在获取软件下选择新的 PPA,然后在右侧面板中选择安装完整的通用 Linux 内核,如果您看到两个,请选择名称中不带 pae 的那个。

重新启动并希望 Linux 之神这次会对我们微笑。

如果您对新内核有任何问题,您可以在启动时按 ESC 键以显示菜单,然后从旧内核启动。

----------- 解决方案:OP 只需构建另一个适配器

通常是最简单的解决方案。
