从挂起/休眠状态恢复后，Debian 测试无法连接互联网

我正在 Dell Inspiron 5567 和 Intel Wireless 3165（驱动程序 iwlwifi）上运行内核 4.14 的 Debian 测试。

我的网络管理器出现问题：从挂起/休眠状态恢复后，我可以连接到无线网络，但没有互联网。我可以通过蓝牙网络共享进行连接（这实际上就是我现在的连接方式）；重新启动后一切正常。以下是可能相关的 dmesg 信息：

我不禁注意到两行：

[  128.421404] r8169 0000:02:00.0 enp2s0: link down

和

[  158.150788] wlp1s0: failed to remove key (1, ff:ff:ff:ff:ff:ff) from hardware (-22)

我用谷歌搜索了它们，但没有出现任何与此相关的内容（显然，它们与经常断开wifi连接有关，这不是我的情况）。

我尝试了列出的解决方案这里但它们都不起作用；以机智：

  1. 通过 systemctl 重新启动网络管理器。

  2. 删除并加载 iwlmvm，然后通过 systemctl 重新启动 nm。

有任何想法吗？谢谢！

编辑：我忘了提到我尝试用 wicd 替换 nm，但删除了后者，因为蓝牙无法正常工作；但是我在某个时候清除了 nm，所以可能配置文件丢失了。

答案1

在内核 4.16.0-2-amd64 和 Realtek r8169 的 Debian stable 上也有同样的问题

r8169 0000:02:00.0 enp2s0: 链路断开

您可以尝试在挂起之前和之后删除并重新加载内核驱动程序。创建文件 /lib/systemd/系统睡眠/重置网络

#!/bin/sh
if [ "${1}" == "pre" ]; then
  # Do the thing you want before suspend here, e.g.:
  rmmod r8169
elif [ "${1}" == "post" ]; then
  # Do the thing you want after resume here, e.g.:
  modprobe r8169
fi

不要忘记使其可执行 chmod 755 /lib/systemd/系统睡眠/重置网络

在某些情况下，路径可能是 /user/lib/systemd/system-sleep/

您也可以添加其他模块！
