刚买了一个TP-LINK TL-WDN5200 usb上网卡，发现没有Ubuntu的驱动，
于是在网页上http://download.csdn.net/detail/u010245383/8466021 下载了驱动
然而make时需要联网下载安装包，台式机本身就连不上网，希望买个无线网卡能连wifi,
这不就成了无线循环？bug了？

插入无线网卡执行以下指令将结果全部复制贴上来

您的无线网卡处于优盘模式，需要切换为无线网卡模式。请您按顺序执行以下步骤

注意，下面的命令输出信息较多，请选中所有文字，按 Ctrl+Shift+C 复制，粘贴到其它地方，再贴上来。不要截图。

1. 执行以下指令检查 usb-modeswitch 是否已安装

如果最后一行开头是 'ii' 说明已安装。如果不是，您需要设法连接有线网安装 usb-modeswitch，或手动下载这几个包拷贝到机器上安装。需要按下面的顺序，先安装第一个，然后是第二个、第三个。下面的软件包适用于 Ubuntu 14.04 amd64
http://kr.archive.ubuntu.com/ubuntu/pool/main/libp/libpipeline/libpipeline1_1.3.0-1_amd64.deb

切换成功，芯片为 148f:761a (MediaTek MT7610U)，内核中无相应驱动支持。尝试到这里：
https://launchpad.net/~hanipouspilot/+archive/ubuntu/rtlwifi/+packages
点击 mt7610u-dkms - 0.2~trusty 左边的三角，再点击 mt7610u-dkms_0.2~trusty_all.deb (990.4 KiB) 下载。下载后，到下载目录使用 sudo dpkg -i mt7610u-dkms_0.2~trusty_all.deb 安装。如果提示缺失依赖，到 https://packages.ubuntu.com/ 搜索下载。注意搜索时 Distribution 选 trusty (14.04)，切记不要选别的。

非常感谢您耐心的回答。我的操作如下：

请问这有可能是什么原因呢？

还出现了一个新的现象，就是打开文件夹一直转圈无响应，感觉上是很卡，挪动文件夹窗口就直接卡死。

可能原因 驱动质量较差
因为厂商发布驱动后一般很少更新，网友们群策群力，对其修修补补。由此产生了许多“民间版本”。到 github 搜索 mt7610u，会发现许多这样的修改版，它们集成的补丁都不一样。到这些项目的 issues 查看，可以发现类似问题。

看看是不是这个问题：https://github.com/ulli-kroll/mt7610u/issues/4
先用 sudo iwlist scan 扫描，看有没有结果
然后停止 NetworkManager : sudo service network-manager stop
再用 sudo iwlist scan 扫描，看有没有结果


跟加载无线驱动有没有关系
