The dummy0 interface adds a default route with metric 1000, which takes priority over the real network interface (e.g. WiFi at metric 20600), causing all traffic to route through a virtual interface with no actual connectivity. Remove the unnecessary default route from both the install step and the systemd service — dummy0 only needs to provide a stable IP for K3s node binding.
