Wi-Fi Not Working? A Step-by-Step Troubleshooting Guide

Most home Wi-Fi problems can be narrowed down with a handful of steps, roughly in order from quickest to most involved.

  1. Restart your router and modem

    Unplug both for about 30 seconds, then plug the modem back in first and wait for it to fully reconnect before powering the router back on. This single step resolves a large share of everyday connectivity issues.

  2. Confirm Wi-Fi is on and connected to the right network

    Check that airplane mode is off and that your device is actually connected to your own network rather than a neighboring one with a similar name, which is an easy mistake to overlook.

  3. Move closer to the router or remove obstacles

    Thick walls, metal appliances, and distance all weaken a Wi-Fi signal. Testing the connection standing next to the router quickly tells you whether the issue is signal strength or something else.

  4. Forget the network and reconnect

    Removing the saved network from your device and rejoining it with the password forces a fresh connection, which can clear up issues caused by a corrupted saved network profile.

  5. Test whether other devices have the same problem

    If only one device struggles to connect, the issue is likely with that device. If every device on the network is affected, the router or the internet service itself is the more likely cause.

  6. Check for an internet service outage

    Use a mobile data connection to check your provider's outage map or status page, since a Wi-Fi network can be working perfectly while the internet service behind it is down.

  7. Update router firmware

    Outdated router firmware can cause stability issues and security gaps. Most routers offer a firmware update option in their admin settings or companion app.

  8. Contact your internet provider

    If none of the above resolves the issue, the problem may be on the provider's end (such as a line issue) or require a technician visit or equipment replacement.

Why restarting fixes so much

A restart clears the router's temporary memory and forces it to re-establish its connection with your internet provider from scratch, which resolves many of the small glitches that build up over days or weeks of continuous operation.

Isolating the problem saves time

The fastest path to a fix is usually narrowing down whether the problem is your device, your router, or your internet service, rather than trying random fixes β€” testing with a second device is one of the quickest ways to tell them apart.

Frequently Asked Questions

Why does restarting the modem and router in a specific order matter?

Powering the modem on first lets it fully reconnect to your provider's network before the router tries to use that connection, which avoids the router getting stuck without a working internet link.

My Wi-Fi shows full bars but pages won't load β€” what does that mean?

A strong signal only means your device is well-connected to the router; it does not guarantee the router itself has a working internet connection, so the issue is more likely with the modem, the router's internet link, or your provider.
