Ubuntu 22.04 wifi 连接每隔 x 分钟丢失一次

Ubuntu 22.04 wifi 连接每隔 x 分钟丢失一次

一两周前,我的 wifi 每隔 10-20 分钟就会断线一次。据我所知,在此之前我没有进行任何更新或任何操作。我尝试了网上找到的各种解决方案,但都无济于事。

我的快速解决方法是使用手机作为 wifi 热点,使用电脑上出错的同一个 wifi。这有效,但显然不是解决办法。

查看系统日志,似乎与 DNS 有关。我尝试将 DNS 更改为 Google (8888/8844),更改省电设置,但这没有帮助。

开始感到绝望了。希望有人能帮忙?

以下是一些网络配置信息的转储: https://gist.github.com/kingkong-cmd/da65b13844db26fbb3a3acf27056c600

发生这种情况时,我的系统日志如下所示。如果我在此之后重新连接,它会再次工作 x 分钟,然后才会发生同样的情况。

编辑:还尝试在 /etc/systemd/resolved.conf 中设置 DNSSEC=no ref: https://superuser.com/questions/1676584/using-degraded-feature-set-tcp-instead-of-udp-for-dns-server
