执行sudo modprobe -r b43 ssb wl brcmfmac brcmsmac bcma
sudo modprobe wl

然后把上面这两个文件夹清空，重启就可以了。

我按你上面步骤做了，重启之后，文件夹也是空的，现在能正常上网。

今晚关机，明天看能不能连上

麻烦提供下终端下lspci -nn，ip link 还有dmesg的输出。

开机一样连不上，关了机再开，就可连上

以太网设备mac地址 默认是不指定设备 ，现在用这个地址看看

你好，根据下面这个网站

https://www.linuxquestions.org/questions/linux-hardware-18/realtek-rtl8111-8168-8411-ethernet-controller-r8168-driver-install-r8169-driver-doesn%27t-work-4175641982/

我制作了一个驱动包。麻烦你安装好后。执行下面的命令，然后反馈。如果解决了你的问题。麻烦在贴子标题加上已解决。

sudo depmod -a
sudo modprobe r8168

才发现无法上传。补上链接。

我按你发的方法做了，但问题是否解决要到明天才知道。现在重启，网卡是能直接连上的，就算关机两三个小时，再开，网卡照样能连上。必须要隔一晚，十几个小时，再开机，才知道是不是还能连上，问题有没有解决。
