When every device joins Wi-Fi but none reaches the internet, focus on modem/ONT, provider status, router WAN address and cabling—not individual device resets.
What this covers
- The observed symptom matches this record
- Customer-accessible settings, connections and external components
- Diagnosis before reset, deletion or component replacement
What it does not cover
- ×A model-specific error code with a different documented meaning
- ×Internal electrical, battery-cell, gas, refrigeration or sealed-component repair
- ×A guarantee that every model exposes the same control label
Capture the exact symptom
ReversibleCheck provider status and modem/ONT lights, then try two unrelated sites on two devices.
Run the smallest isolation test
ReversibleRestart in provider order: modem/ONT first until online, then router, then one test device; inspect the WAN cable.
Correct only the proven cause
ReversibleCorrect the upstream outage, account/provisioning issue or failed WAN cable identified by status and lights.
Verify before changing anything else
ReversibleConfirm two devices can load sites and a video after the network has been stable for ten minutes.
