# Internet Is Completely Down

No devices in your home or office can reach the internet, even though Wi-Fi may still appear connected.

Network & Wi-Fi

### Step-by-Step Diagnosis

1. **Check if Wi-Fi is connected** — If your device shows a Wi-Fi connection but no internet, the issue is likely with your router or ISP, not your wireless network.
2. **Check the modem/ONT** — Look at your ISP modem or fiber ONT (the box where the internet enters your building). Are the lights normal? A solid or blinking "Online" or "Internet" light means ISP connectivity is good.
3. **Power cycle in order:**
 \- Unplug the **modem/ONT** (wait 30 seconds, plug back in, wait 2 minutes) - Then unplug the **router** (wait 30 seconds, plug back in, wait 2 minutes)
1. **Test with a direct connection** — Plug a laptop directly into the modem via Ethernet. If that works, the issue is with your router. If it doesn't, the issue is with your ISP.
2. **Check for ISP outages** — Visit your ISP's status page or call their support line.
