No Internet After a Power Outage: What to Check Before Resetting Everything

If you have no internet after a power outage, do not press the factory-reset button first. A brief outage can leave the modem, router, or internet provider’s equipment out of sync even after household power returns. Start with an outage check and a deliberate restart order before changing passwords or erasing your network settings.

These steps are for a connection that worked before the outage and now affects one or more devices. If only one phone, computer, or TV is offline while other devices work, begin with that device instead; our Wi-Fi connected but no internet checklist can help.

First: do not reset the modem or router

A factory reset is not the same as a restart. It can erase your Wi-Fi name and password, provider-specific settings, mesh configuration, port forwarding, and other details. After a power outage, a normal power cycle solves many problems without creating a larger setup job.

Also avoid repeatedly unplugging and reconnecting equipment in quick succession. Modems and gateways need time to communicate with the provider again after power returns.

1. Check whether the outage is still outside your home

Use mobile data—not your home Wi-Fi—to check your internet provider’s outage page, app, or support number. A neighborhood outage can continue after your lights are back on, especially if local equipment, poles, or cabinets lost power. Ask a nearby neighbor with the same provider if their service is working, but do not rely on a different provider as proof that yours is restored.

If the provider reports an outage, leave the equipment powered on unless its instructions say otherwise. The connection may recover automatically when the provider finishes repairs.

2. Check power, cables, and status lights

• Make sure the modem, gateway, and router are plugged into a working outlet or surge protector.
• Confirm that the power strip was not switched off or tripped during the outage.
• Press each power connector gently into place; a plug can work loose while equipment is moved.
• Check the cable from the wall to the modem or gateway and the Ethernet cable between a separate modem and router.
• Look at the labels for the lights rather than relying only on their color. Names vary by provider and model.

On many devices, a power light should become steady first. The internet, online, or WAN light may blink while the device reconnects, then become steady only after the provider authorizes the connection. Consult the label or manual for your specific model before treating any particular color as an error.

3. If you have a separate modem and router restart them in the right order

If you have two boxes—a modem connected to the wall and a separate Wi-Fi router—restart them in this order:

1. Unplug the router’s power.
2. Unplug the modem’s power.
3. Wait about two minutes.
4. Plug in the modem only. Give it several minutes to finish starting and reconnecting to the provider.
5. When the modem appears stable, plug in the router and wait another few minutes for Wi-Fi to return.

If you have a single provider gateway that combines the modem and router, restart that one device once and then give it time to complete its startup sequence. Do not add a separate-router step that you do not actually have.

For a broader explanation of the equipment roles, see how to tell whether the router or internet provider is the problem.

4. Test the connection before changing Wi-Fi settings

Once the modem and router have had time to settle, try a phone and a computer. If both can join Wi-Fi but neither can open websites, the problem is likely between the modem or gateway and the provider. If a wired Ethernet connection works but Wi-Fi does not, the internet service may be restored and the remaining problem is in the router’s wireless side.

When several devices cannot get online, follow the network-wide checks in our Wi-Fi not working guide rather than forgetting networks on every device.

Warning signs after a surge or electrical event

A normal outage does not automatically mean the equipment is damaged. However, stop using the device and contact the provider, manufacturer, or a qualified technician if you notice a burning smell, unusual heat, visible damage, a swollen power adapter, repeated unexpected restarts, or no power light when a known-good outlet is used. Do not open a modem, router, power adapter, or surge protector yourself.

Also check whether the surge protector itself was damaged or switched off. A surge protector can sacrifice itself during an electrical event, so the outlets on it may no longer provide reliable power.

When a factory reset is appropriate

Consider a factory reset only after the provider confirms service is available, the normal restart sequence has failed, the cables and power are sound, and you know how the equipment was configured. Before resetting, record the Wi-Fi name, password, provider login details, and any special settings. Provider-owned gateways may need to be reactivated or remotely provisioned after a reset.

Frequently asked questions

How long should internet take to come back after a power outage?

It can take several minutes after the modem starts, and longer if your provider’s network is still recovering. If an outage is reported, there may be no useful local fix until the provider restores service.

Why is my Wi-Fi network visible but there is no internet?

Your router can still broadcast Wi-Fi even when it has not reconnected to the modem or the provider. That means devices can join the network but cannot reach the internet.

Should I unplug the modem and router at the same time?

Yes, when doing a normal restart, but power the modem back on first and wait for it to stabilize before powering the router. That order gives the router a working internet connection to use when it starts.

Can a power outage damage a modem or router?

It can, particularly if a surge accompanies the outage, but many post-outage failures are temporary reconnection or provider-outage issues. Check for the warning signs above before assuming permanent damage.

The short version

Check for a provider outage first, confirm power and cables, then restart a separate modem before the router. Give each device time to reconnect and test more than one device before changing Wi-Fi settings. Treat a factory reset as a last resort, and stop using equipment that shows signs of electrical damage.
