Can’t Connect to Internet? Fixes That Work

If you see “Unable to connect to the internet,� the fix is usually one of a few simple steps: restart your modem and router, forget and rejoin the Wi‑Fi network, or run the built‑in network troubleshooter. Below are the most effective solutions, ordered from simplest to more advanced, plus the background on why these errors happen.

Why This Error Happens

The “unable to connect� message appears when your device cannot establish a link to your local network or through it to the internet. Common causes include:

A temporary glitch in your modem, router, or device’s network stack
Wi‑Fi signal interference or being out of range
Incorrect Wi‑Fi password or network settings
ISP (internet service provider) outage in your area
Outdated network drivers (on Windows) or network settings (on Mac/iOS/Android)
IP address conflicts or DNS problems

Understanding the cause helps you pick the right fix. Most of the time, a simple restart clears the issue.

Quick Fixes to Try First

Start with these, as they resolve the majority of cases:

Restart your modem and router. Unplug both, wait 30 seconds, plug the modem back in, wait for it to fully boot, then plug in the router. This clears temporary crashes and renews your IP address.
Toggle Wi‑Fi off and on on your device. On a phone, swipe down and tap the Wi‑Fi icon. On a computer, click the network icon in the system tray and turn it off, then on.
Forget the network and reconnect. Go to Wi‑Fi settings, select your network, choose “Forget,� then rejoin by entering the password again. This fixes corrupted saved credentials.
Run the built‑in troubleshooter. On Windows: Settings → System → Troubleshoot → Other troubleshooters → Internet Connections. On macOS: System Settings → Network → select your connection → “Diagnostics.� On Android/iOS: no built‑in tool, but you can use the steps above.

Advanced Solutions for Persistent Problems

If quick fixes don’t work, try these in order:

Release and renew your IP address. On Windows, open Command Prompt (admin) and type ipconfig /release then ipconfig /renew. On macOS, go to System Settings → Network → TCP/IP → “Renew DHCP Lease.�
Flush DNS cache. In the same Command Prompt, type ipconfig /flushdns. This clears corrupted DNS entries that can block internet access even when the network is fine.
Change DNS servers. If your ISP’s DNS is down, switch to a public DNS like Google (8.8.8.8 and 8.8.4.4) or Cloudflare (1.1.1.1). You can do this in your router’s settings or on your device.
Update network drivers. On Windows, open Device Manager → Network adapters → right‑click your Wi‑Fi or Ethernet adapter → “Update driver.� On macOS, updates come with system updates.
Disable VPN or proxy. Sometimes a VPN or proxy setting interferes. Turn it off temporarily to test.

When It’s Not Your Device: Router and ISP Issues

If multiple devices can’t connect, the problem is likely your router or your ISP. Check if the router’s internet light is solid (not blinking red). If it’s off or red, try a factory reset (press the reset button with a paperclip for 10 seconds) and reconfigure your network name and password. If that doesn’t help, contact your ISP to check for outages in your area—they often have a status page or you can call.

How to Read the Error Message

Different messages point to different issues:

“No internet, secured� – you’re connected to Wi‑Fi but have no internet access. Usually a router or ISP problem.
“Can’t connect to this network� – often a wrong password or signal issue.
“IP configuration failed� – your device can’t get an IP address, so restart the router or renew DHCP.
“DNS probe finished no internet� – DNS issue, so flush DNS or change DNS servers.

Prevention Tips

To reduce future occurrences:

Place your router in a central, elevated location away from walls and metal objects.
Keep your router’s firmware updated (check the manufacturer’s app or admin page).
Use a strong, unique Wi‑Fi password to prevent unauthorized users from slowing your connection.
Restart your router monthly to clear memory leaks.
If you have many devices, consider a mesh Wi‑Fi system for better coverage.

Frequently Asked Questions

Why does my phone say “unable to connect� but other devices work?
This usually means the phone’s saved network settings are corrupted. Forget the network and reconnect, or restart the phone. If that fails, check if you have a VPN or ad‑blocker that might interfere.

How do I fix “No internet, secured� on Windows?
Run the network troubleshooter, then try releasing/renewing the IP address and flushing DNS. If that fails, restart your router. If only one Windows device has the issue, update the network driver.

Can a faulty Ethernet cable cause this?
Yes. If you’re using a wired connection, a damaged or loose cable can cause intermittent disconnects. Try a different cable or port on the router.

Why does my internet work on some apps but not others?
This often indicates a DNS or firewall issue. Some apps may cache old DNS entries. Flush DNS and restart the app. Also check if the app has its own network permissions (e.g., on iOS, Settings → Privacy → Local Network).

Should I reset my router to factory settings?
Only as a last resort, because it erases all custom settings (Wi‑Fi name, password, port forwards). If you do it, you’ll need to reconfigure everything. Try power cycling first.

How do I know if it’s an ISP outage?
Check your ISP’s status page or call them. Also, if your router’s internet light is red or off, that’s a strong sign. You can also see if other people in your area report issues on social media.
