Ubuntu 18.04(新笔记本电脑)wifi 连接但无互联网

我刚买了一台 Acer Aspire 7,安装了 Ubuntu 18.04 LTS。我可以通过有线连接访问互联网,但当涉及到 wifi 时,它似乎已连接到我的,但实际上没有互联网访问。我不确定为什么我无法访问它。我得到了这个:

  *-network                 
       description: Wireless interface

       resources: irq:128 memory:a4200000-a43fffff

我是否需要一些驱动程序或者别的东西?如果是的话,需要什么呢?

编辑。iwconfig 给我以下内容(如果有任何帮助的话):

~$ iwconfig
