每当我插入充电器时，我就会断开互联网连接。我不会断开 wifi 连接，wifi 信号保持良好。当我插入充电器时，我无法通过它获取任何数据或只有很少的数据。
我在华硕 Zenbook 上安装了双启动的 Windows11 和 Ubuntu20.04 系统。Windows 端没有问题，所以不可能是硬件问题，对吧？
我在这个互联网连接上有大量其他设备，从来没有出现任何问题，所以我不认为这是路由器/调制解调器/ISP 的问题（Xfinity 与调制解调器/路由器组合）。
我可以插入以太网电缆，无论是否充电，都不会出现任何问题。
当我拔下充电器时，有时我必须重新启动网络管理器才能重新建立连接（sudo service network-manager restart）。其他时候，我可以直接拔下充电器并立即获取数据。
拔下充电器后，我可以正常 ping google.com：
➜ ~ ping google.com

rtt min/avg/max/mdev = 12.058/13.490/14.922/1.432 ms
当我重新插入充电器并尝试ping google.com充电时，它只是挂起，或者有时会有一些数据包通过，但速度非常慢。最终我开始看到，ping: sendmsg: No buffer space available或者有时ping: google.com: Temporary failure in name resolution
当我在拔下电源的情况下尝试 ping 我的 Xfinity 的 DNS 时，一切看起来都很好。
当我在充电时尝试 ping DNS 时：
➜ ~ ping 75.75.75.75

这是我的 iwconfig：

这是我的 /etc/resolv.conf
➜ ~ cat /etc/resolv.conf

# NOTE: the libc resolver may not support more than 3 nameservers.
# The nameservers listed below may not be recognized.
nameserver 2001:558:feed::2
我尝试关闭 wlo1 连接的电源管理模式，但没有任何反应。
➜ ~ sudo vim /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
...
[connection]
wifi.powersave = 2
...
➜ ~ sudo service network-manager restart
我尝试在“/etc/resolv.conf”中手动更改我的 DNS，但没有帮助。
我已经尝试了 IPv4、IPv6、DHCP、自动 DHCP 的所有组合、手动设置 DNS 以及 Ubunutu 设置应用程序中的所有其他 wifi 连接设置，但没有任何帮助。
我已在 UEFI 设置中关闭快速启动和安全启动。
这就是真正奇怪的地方：当我连接到手机热点时，无论是否充电，都没有连接问题。此外，我之前用同一台机器使用过不同的互联网，从来没有遇到过任何问题。这就像是我的路由器/调制解调器和电源插入的组合？
任何帮助都将不胜感激。我完全被这个问题难住了。
编辑：我尝试了@Terrance 的建议，在我的路由器上分割 2.4 和 5Ghz 通道，但没有帮助。
编辑：我还注意到，当我插入充电线时，偶尔会出现一些奇怪的现象，它会发出噪音，但电池图标永远不会变为充电图标。这种情况是随机发生的，并非总是如此。似乎对互联网连接没有任何影响。
答案1
好吧，我想我已经搞清楚了。我注意到系统日志中显示，当机器插入电源时，网络适配器不断重新启动。仍然不确定原因。这是提醒我的日志，我每隔一分钟左右就会看到它：
