我已经遇到这个问题好几天了，我的 ubuntu 机器经常与网络断开连接，最后我终于找到了原因：
Jun 11 10:40:19 nvidia avahi-daemon[886]: Withdrawing address record for 192.168.1.200 on enp4s0.
Jun 11 10:40:19 nvidia avahi-daemon[886]: Leaving mDNS multicast group on interface enp4s0.IPv4 with address 192.168.1.200.
Jun 11 10:40:19 nvidia avahi-daemon[886]: Interface enp4s0.IPv4 no longer relevant for mDNS.
有人能帮我理解导致这种情况发生的原因以及修复它的最佳方法吗？我以为最简单的方法是禁用 avahi-daemon，但这似乎是非常由于某种原因，弹性服务。
我发现 .local dns 地址有问题，但不确定如何使用我的路由器（AsusWRT）解决这个问题。
