1. Router Profile
💡 Why Rebooting Works: Most consumer routers run stripped-down Linux micro-kernels. Dormant TCP state sockets, orphaned DHCP leases, fragmented kernel buffer heaps, and DFS radio drift accumulate linearly with uptime until cleared by a power cycle.

- Isolate ISP line faults vs Router memory leak: Run
ping 192.168.1.1 -c 50directly to the gateway. If LAN latency fluctuates past 15ms or drops packets, the router is buffer-exhausted. - DNS Cache Stagnation: If websites stall on first load but download quickly once connected, your local resolver daemon (dnsmasq) has stalled. A soft reboot clears cache poisoning and stale lookups.
- Smart Plug Safety: Always choose a smart plug with local LAN fallback (Zigbee, Z-Wave, or Tasmota/Matter) so it can automatically turn back ON even when internet connectivity drops.
