问题应该出在这里，可是这么解决啊

我的同样问题，都搞两天了.不过我的USB无线网卡是TL-WN725N 3.0的，我以把lsusb和sudo dmesg上传，老机油们老看看在下谢了！

楼主你的搞好了没啊？搞好了说下方法在线等呢。

装了个软件以后只有这里报错了，后面的没事了，可是还是上不了网

再自己顶一下，看有没有大神能解决啊

要不重装一次试下，我现在U盘又不在手上没法试，如果你们U盘在手上可以试下

重装了一遍，问题还是一样，启动信息已经不报错了，可是还是不行就是连不上，我无语了，有点怀疑人生了

我昨天刚装好时是能正常连接的，我还下载了一些软件，后来关机重起后就不能用了，没搞明白什么原因

我已经放弃15.7了，准备装15.8试试，不行就装2014试试，总有一个能用吧

我彻底无语了，装了个15.8，装完重启以后奇迹的连上了，然后重新启动以后再连接怎么也连不上了，郁闷死了

用Windows吧,就没这些问题了.或者换个无线网卡
