Light Statuses for UG-101 and UG-204 Gateways

Decode the front-panel LED states on the UG-10x and UG-204 gateways to diagnose DHCP, DNS, and cloud connectivity problems at a glance.

The front-panel LEDs on the UG-10x and UG-204 gateways tell you where in the connectivity chain the gateway is stuck. Use the table below to map a symptom to its meaning.

Symptom by gateway model

Condition UG-10x indicator UG-204 indicator
Cannot acquire a DHCP address A light is off Aux Internet light is blinking
Cannot complete DNS queries Status light is orange Local 2 light is blinking
Cannot reach the cloud Status light is orange Local 1 light is blinking
Reporting to the cloud successfully Status light is green Main Internet steady green, no other green lights blinking

The orange UG-10x status light is the same colour for “no DNS” and “no cloud” — distinguish them by checking whether DNS resolution works from a LAN device before escalating.

Additional UG-10x status colours

  • Blue — gateway is downloading its configuration from the cloud. Wait for it to finish.
  • Purple — firmware update in progress. Do not power-cycle.
