第一次提问！
我正在尝试使用我的新 Acer Aspire F15 笔记本电脑连接到我大学的 wifi，并且我运行的是 Ubuntu 16.04.2 LTS 64 位。我以前在家里连接 wifi 没有任何问题，我可以通过手机热点连接到互联网。问题是不是我无法连接到路由器 - 它让我连接正常。但是，一旦连接，我就无法连接到互联网。我还咨询了 IT 服务部门，据说我已经正确设置了所有设置（包括使用证书 - 请参阅附件中的设置）。将这些相同的设置与运行相同 Ubuntu 发行版的旧款 Acer 笔记本电脑一起使用，运行正常。
这个问题也并不一致。我去了我所在大学的 IT 帮助台，删除了连接，然后重新连接，在大楼里就可以上网了。然而，回到办公室后，我再也无法上网了，删除并重新连接也无法解决问题。我问过 IT 台他们是否有任何见解，但他们似乎力不从心，因为他们几乎只使用 Windows 和 Mac。
我尝试了该网站提供的不同解决方案，包括在文件的部分auth-alg=open内进行设置，但没有成功。[wifi-security]/etc/NetworkManager/system-connections/wpa.mcgill.ca这个人似乎有与我类似的问题，没有解决方案。
我附上了一张显示我的连接设置的截图（为了便于查看，我删除了我的用户名和密码）。我还附上了一些我听说过的命令的相关输出，以节省您的时间（我认为应该删除一些细节，用 # 符号代替）。如果您需要任何其他输出，请告诉我！
任何帮助都将不胜感激！我不想继续使用我的手机数据……

更新：
从4.4.0-72-generic内核升级到4.8.0-46-generic内核并没有解决我的问题...仍然没有解决方案。
