查询无线网卡，没有显示～～～求有没有知道怎么回事的，初入linux～～搞 了好几天了

1. 拔出无线网卡
2. 打开一个终端，执行 sudo dmesg -w，保持终端开启
3. 插入无线网卡
4. 将步骤 2 的终端中新刷出的信息全部复制贴上来，不要节选
5. 执行以下指令将结果全部复制贴上来，不要节选

代码： 全选

uname -a
cat /etc/issue
find /lib/firmware | grep mt7601u.bin | xargs ls -l
sudo lshw -numeric -C net

先说明一下我的网卡情况，TL-wn726N 免驱动版的，每次进linux还要把网卡挂载模式从光盘模式变为网卡模式，我下面贴出曾需运行结果，看看性不 不行我就换个网卡

这个信息太多了～～复制粘帖不上来，输出到文本，又体现不出来插入网卡后的变化～～～～

[gwt600]

搞了快一周时间，我只想说呵呵~~ 这个问题，老外那边描述的很详细，算是bug还是算啥不好说，我按照指导，把ubuntu换成Ubuntu 15.04，还是报以前的错，搜索国外帖子时，有个别人描述 MT7601U芯片是一个便宜的，支持不好的芯片，反正不是什么好话。折腾半天，确认了，这玩意 确实不好弄啊~~~搞不定，重买一块网卡吧还是~~原谅我的蠢~~~~望后续读到这个帖子的人成功了的话，记得留言~~，看看到底是怎么整的~~

[gwt600]

这个ubuntu 网站，有点小毛病啊，跟帖之后，跳转到错误的页面上，还以为没有发帖成功呢，一回退，再提交又成重复内容了~~有待改进啊

[safirst]

我也无语了，我的问题（包括输出）跟你的一模一样，但是这么多年过去了，无人能解呀。
