我刚刚在 HP pavillon 15-p088ca 上安装了 Kubuntu，一切都很正常，只是我的互联网停止响应了。我尝试 ping localhost：一切正常，尝试 ping google.com：没有结果...我发现的唯一解决方案是关闭/打开 wifi，但几分钟后它仍然停止...
这是我的网络配置：
eti@eti-kubuntu:~$ sudo lshw -class network

我检查了内核版本：
eti@eti-kubuntu:~$ uname -nr
eti-kubuntu 4.2.0-25-通用
但根据这个网站我的内核版本支持我的网卡驱动程序： https://wireless.wiki.kernel.org/en/users/drivers/rtl819x
请问你能帮帮我吗？？
谢谢 ：）
