Wi-Fi Connected but No Internet? Find the Problem in 3 Steps

Updated November 7, 2026 · The Computer Hospital, Midtown Houston

The Wi-Fi icon shows full bars, but nothing loads, and Windows says "No internet, secured." This is one of the most confusing computer problems, because being connected to Wi-Fi and being connected to the internet are two different things. Your computer can have a perfect link to your router while the router itself has no internet — or the router can be fine while one computer is misconfigured. The trick is figuring out which.

Step 1: Is it one device or everything?

This single question cuts the problem in half:

• Every device is offline (phones on Wi-Fi, TVs, other computers) → the problem is your internet service, modem or router. Go to Step 2.
• Only one computer is offline while everything else works → the problem is that computer. Go to Step 3.

Tip: turn off your phone's Wi-Fi briefly and use cellular data to check your provider's outage page.

Step 2: When everything is offline

1. Check for an outage. Look up your internet provider's outage map or app from your phone's cellular data.
2. Look at the modem's lights. A red, orange or blinking "online" or "internet" light usually means the problem is upstream — the provider or the line.
3. Restart in the right order: unplug the modem and the router, wait 30 seconds, plug in the modem first and wait until its lights settle (a few minutes), then plug in the router.
4. Still down? Call your provider. If the modem shows "online" but the router doesn't pass internet, the router may need resetting or replacing.

Step 3: When only one computer is offline

1. Turn Wi-Fi off and on, or toggle Airplane mode on and off.
2. Restart the computer (a real restart, not just closing the lid).
3. Forget the network and reconnect: Settings → Network & internet → Wi-Fi → Manage known networks → Forget, then reconnect with the password.
4. Check for a VPN or proxy left on, or security software that's blocking the connection.
5. Try a network cable if you have one. If wired works and Wi-Fi doesn't, the Wi-Fi adapter or its driver is the likely problem.
6. Windows network reset: Settings → Network & internet → Advanced network settings → Network reset. This reinstalls network adapters — note that it also removes saved Wi-Fi networks and VPN settings, so have your passwords ready.

When it comes and goes

If the internet drops out in certain rooms or at certain times, the cause is usually coverage, not the computer:

• Dead spots: brick, plaster, concrete, metal and long hallways weaken Wi-Fi. One router at one end of the house often can't cover it all.
• Crowded channels: in apartments and high-rises, dozens of neighboring networks compete on the same channels.
• An aging router: routers several years old often can't keep up with today's number of devices.

A mesh Wi-Fi system — several units that work together — usually fixes dead spots far better than range extenders.

How we help

Bring the computer to our shop and we'll start with one simple test: we connect it to our network. That answer decides everything that follows.

• It works at our shop. Then the computer is fine and the problem is at your location — the router, the modem, the Wi-Fi coverage or the network setup. That calls for an on-site visit, where we test your network where it actually lives and fix it there: router setup or replacement, mesh Wi-Fi for dead spots, and securing the network.
• It doesn't work at our shop either. Then the problem is the computer, and we begin diagnostics. We determine whether it's hardware — a failing Wi-Fi adapter, antenna or connection — or software — drivers, network settings, a VPN or security program that's interfering, or damaged Windows networking — and take the repair in that direction.

For offices we also handle firewalls, office Wi-Fi, guest networks and remote access. See network & Wi-Fi and business IT.

Frequently asked questions

What does "connected, no internet" mean?

Your computer is connected to the router, but it can't reach the internet through it. Either the router has no internet, or the computer's network settings are wrong.

Why does my phone work but my laptop doesn't?

Then the internet is fine and the laptop is the problem — usually its Wi-Fi settings, driver, a VPN or security software. Bring it in and we'll test it on our network to confirm.

Should I buy a Wi-Fi extender?

Extenders often cut speeds and create a separate network that devices handle poorly. A mesh system is usually the better fix for dead spots.

Does restarting the router actually help?

Often, yes — restart the modem first, then the router. If you need to do it regularly, the router may be failing or overloaded.
