(SYS blinking = no connection yet) * Does it matter which USB-C port powers it? (No — both share one +5V rail) * My phone won't do USB tethering — why? (Node can't emulate a NIC; use USB-Ethernet dongle + cable; enable tethering after the node is up) * Is there a data buffer when offline? (No — MQTT live-stream by design; only position/MAPEM are sensible cache candidates) * Which antennas can I use? (→ hardware:antennas) * Why is my node so hot? (→ reception:thermal) * Why is reception poor despite good height? (→ reception:interference — nearby 5 GHz APs) * How do I monitor my node in Home Assistant? (→ software:home-assistant) * PoE vs USB / jumper settings? (→ hardware:power)
