我搜索过同样的问题，也发现一些类似的问题，但没有一个解决方案对我有用。
我有一台运行 ubuntu server 22.04.3 的电脑，它的 wifi 适配器设置为
192.168.1.111
我可以通过 SSH 达到上述目的，一切正常。
我使用以下地址建立了一个以太网连接，IP 地址为 192.168.2.22
/etc/netplan/50-cloud-init.yaml
我有一台带 192.168.2.64 的相机
当我通过 wifi 连接并连接以太网线时，它会断开 wifi 连接并保持断开状态。
目前我正在通过以太网使用 ssh 连接，但我需要能够访问互联网。
所以我尝试过，
检查 bios 中与 wifi/以太网相关的任何内容，没有任何可关联的设置。
检查了网络管理器中 ipv4 选项卡下的路由，以便选项“仅将此连接用于其自身网络上的资源”检查了连接文件
[connection]
id=Ethernet connection 1
uuid=8eac2307-8e13-4dca-ae46-d45552704db5
type=ethernet
interface-name=enp2s0
[ethernet]
mac-address=64:00:6A:16:A5:66
[ipv4]
address1=192.168.2.22/24
method=manual
never-default=true
[ipv6]
addr-gen-mode=stable-privacy
method=ignore
[proxy]
配置以太网静态地址时，我没有配置默认网关，因为它告诉我网关与“从不默认”不兼容
我已经将WIFI连接的优先级提高多了。
我还应该尝试其他什么故障排除方法吗？

当使用 GUI 登录时，以太网连接显示从未使用过，即使我使用它通过 SSH 连接到服务器。

192.168.1.110/24 是我之前用于以太网 NIC 的 IP 地址。我已将其删除，但问题仍然存在。
还有另一条路由供 wifi 和以太网到网关，我删除了以太网路由。
