无法在特定网络上解析 Ubuntu 20.04 上的 DNS

Question

我只在我父母家遇到 DNS 解析问题，我真的不明白。这是我唯一遇到这个问题的地方。

我的感觉是systemd-resolved配置不正确。当我使用“坏了的”wifi时，我会看到很多这样的消息：

Using degraded feature set (TCP) for DNS server 192.168.0.1.

当我切换到我的热点时，那里就只有几个了。

这是我的/etc/resolv.conf

nameserver 127.0.0.53
options edns0 trust-ad

这是我的resolvectl status

resolvectl status --no-pager

我可以 ping 通公共互联网：

ping 8.8.8.8

我已经启用debug日志记录，systemd-resolvd因为这是我的直觉，但可能是错的。
