Wi-Fi & Internet Error Messages Explained

Wi-Fi Router Lights Are Off or Blinking Red

Your Wi-Fi router is not working properly. If the lights are off, it may not have power. If blinking red, it is indicating a problem.

Connected, No Internet

Your device is connected to the Wi-Fi network but cannot actually reach the internet. The problem is usually with your router or internet provider.

DNS Server Not Responding

The system that translates website names (like google.com) into addresses is not working. Think of it like a broken phone book — your phone cannot look up where to go.

Limited Connectivity

Your device has a partial connection to the Wi-Fi network but cannot use the full internet. It is like being half-connected.

IP Address Conflict

Two devices on your network are trying to use the same address, which is like two houses having the same street number. They cannot both work properly.

Wi-Fi Keeps Disconnecting

Your device keeps losing its Wi-Fi connection and reconnecting. This unstable connection makes it hard to use the internet reliably.

Can't Connect to This Network

Your device cannot connect to the Wi-Fi network you selected. This could be a password issue, a signal problem, or a device glitch.

No Wi-Fi Networks Found

Your device cannot find any Wi-Fi networks at all. The Wi-Fi antenna on your device may be turned off, or there are no networks in range.

Ethernet — Network Cable Unplugged

Your computer thinks the network cable (ethernet) is not connected, even though it may be plugged in. The cable or port might have an issue.

Secure Sites Not Loading — Date and Time Error

Secure websites (HTTPS) are not loading because your device's date or time is set incorrectly. Security certificates check the date to work.

The Network Security Key Isn't Correct

The Wi-Fi password you entered is wrong. The "network security key" is just a technical term for your Wi-Fi password.

Internet Connection Is Very Slow

Your internet is working but much slower than normal. Pages take a long time to load and videos keep buffering.

Enter Password for Wi-Fi Network

Your device is asking for the Wi-Fi password, and you may not remember it. Here is how to find it.

5GHz Wi-Fi Network Not Showing Up

Your device cannot see the faster 5GHz Wi-Fi network from your router. You may only see the slower 2.4GHz network.

Connected to Neighbor's or Unknown Network

Your device automatically connected to someone else's Wi-Fi network instead of yours. You should disconnect and connect to your own network.

Wi-Fi Connected But Browser Shows Login Page

You connected to a public Wi-Fi network (like at a cafe, library, or hotel) but need to sign in or agree to terms before you can use the internet.
