No internet connection at all

Symptoms

• No device in the house can load any website
• Modem's internet or online light is off, red, or blinking abnormally
• Router shows Wi-Fi working locally but no internet access
• Problem started suddenly with no changes made

Likely causes

• CommonModem or router needs a restartBoth devices can lock up over time and simply need to be power cycled to reconnect properly.
• CommonISP outage in your areaA problem on the provider's network affects everyone in the area at once, regardless of your equipment.
• PossibleLoose or damaged cable between the wall and the modemA coax, phone, or fiber cable connection that's loose or damaged can cut off the signal entirely.
• PossibleUnpaid bill or account issueSome providers suspend service for billing issues, which looks identical to a technical outage.

What to do

1. Check the modem's lights against the manual or the label on the device; a red or off internet/online light usually confirms no signal is reaching it.
2. Unplug the modem for 30 seconds, plug it back in, and wait 2–3 minutes for all lights to return to normal before testing again.
3. Unplug the router as well (if separate from the modem) for 30 seconds after the modem is back online, then plug it back in.
4. Check the physical cable connections at both the wall outlet and the back of the modem, making sure they're firmly seated.
5. Use your phone's cellular data to check your provider's outage map or status page, or call their support line.
6. Confirm your account is in good standing and no recent billing issue could have caused a suspension.
7. If the modem's lights still show no signal after a restart and cable check, and there's no known outage, request a technician visit, since the fault is likely in the line to your home.

When to call a pro

If a restart and cable check don't restore service and there's no listed outage, your ISP will typically send a technician to check the line into your home at no cost if the fault is on their side.
