我有一张 Ralink 的无线 N 卡。在芯片上我读到数字“RT3062f”。我正在运行 Ubuntu 11.10。
在全新安装的 Ubuntu 上，卡可以被识别，但未检测到任何信号（这不太可能，因为它位于路由器旁边，并且我所有其他设备都连接良好）。
我尝试从卡附带的 CD 安装驱动程序，但无法编译。我还尝试从 Ralink 网站下载驱动程序，但安装后，卡根本无法扫描。
以下是一些我认为方向正确的论坛帖子链接：

好的，是的，您确实需要安装 Ralink 的驱动程序才能使该卡工作。但是有一个更新的版本可用。我使用的是 4.1.1 版。我建议您找到并下载该版本。它应该可以从 Ralinktech 网站获得。
获取驱动程序后，将其展开到其自己的目录中。从该目录运行“sudo make”，然后运行“sudo make install”。然后运行“sudo modprobe rt3562sta”。您的无线网络应在几秒钟内启动。
将默认模块 rt2800pci 列入黑名单也是一个好主意。
此外，每次 Linux 内核升级到更高版本后，您都必须重新安装此驱动程序。
