Work through these checks
Identify the two powered devices
Check both power connections and the adapter switch. The dish coax connects to Satellite In on the adapter; its Ethernet cable connects to the gateway WAN port. Inspect the existing routing without loosening coax or swapping cables.
What the result means: Viasat Wi-Fi Gateway 3 residential installation with separate Network Power Adapter. Not SB2+, RM4100/RM4200 or fiber equipment.
Compare Status with Internet WAN
White Status with blinking white WAN means connection is being attempted; white Status with red WAN means the internet link is down. Blinking white Status with red WAN also appears during boot or software update. Record the combination and whether it changes before deciding it is a persistent fault.
What the result means: Read the label of each light. An online Gateway 3 can have a white Status light while WAN and Wi-Fi indicators go dark after ten seconds.
Separate a local Wi-Fi problem
Move closer and check the correct network name privately. Compare another device or an existing Ethernet connection. If only one device fails, troubleshoot that connection first. If both fail, record the WAN light and adapter state for support; avoid a factory reset that erases Wi-Fi setup.
What the result means: Keep account and admin credentials private. Preserve network settings; do not press Reset or move the dish to investigate an indicator. Stop for damaged cables or electrical faults.
