Can’t Connect to Router? Troubleshoot Wi-Fi and Internet

If your phone, computer, or other device cannot connect to your router, first restart the device and router, then check whether the problem affects one device or every device. If only one device is affected, troubleshoot its Wi-Fi settings; if several devices fail, check the router, its cables, and the internet connection.

Start with the simplest checks

Confirm that Wi-Fi is turned on and airplane mode is off. Check that the device is trying to join the correct network name (SSID), especially if nearby routers have similar names. Enter the password carefully; it is case-sensitive, and a saved password may be out of date after a router change.

Move close to the router and try connecting again. Distance, walls, and interference can weaken a signal.
Turn Wi-Fi off and back on, or restart the device. This can clear a temporary connection problem.
Restart the router by unplugging its power, waiting about 30 seconds, and reconnecting it. Allow several minutes for it to start. Do not press its reset button: a factory reset can erase custom settings.
Check the router’s power and network cables. Make sure the cable from the modem or internet service connection is firmly attached to the router’s WAN or Internet port, if your setup uses a separate modem.

Router lights differ by model, so use the device’s manual to interpret them. A power light alone does not prove that the router has internet access.

Find out whether the router or device is at fault

Try connecting a second device to the same Wi-Fi network. If it connects normally, the router and internet service are more likely to be working, and the original device is the best place to investigate. If no device can join, focus on the router, its configuration, or the service connection.

Also distinguish between joining Wi-Fi and reaching the internet. A device can be connected to the router’s local network while showing “No internet.” In that case, it has established a wireless link, but the router may not be receiving service from the modem or provider. Open the router’s local management page or app only if you know how to access it; its connection status may help separate a Wi-Fi problem from an internet outage.

If possible, test a computer with an Ethernet cable connected to the router. A working wired connection alongside failed Wi-Fi points toward a wireless setting or radio issue. If wired devices also lack internet, check the modem, service status, and router’s WAN connection.

Check the network name, password, and settings

Routers may offer separate 2.4 GHz and 5 GHz networks, or combine them under one name. The 2.4 GHz band generally reaches farther; 5 GHz can offer higher speeds at shorter range, depending on the devices and surroundings. If both bands have separate names, try the other one. Some older or specialized devices do not support every Wi-Fi band or security mode.

On the device, use the option to forget or remove the saved network, then select it again and enter the current password. This is useful after a password or router change because the device may keep trying old credentials. Avoid changing router security settings at random: outdated or incompatible settings can create new connection problems. If you need to change them, consult the router and device documentation and use a currently supported security mode.

A network may also be hidden or restricted by settings such as access controls, a device limit, or a guest-network configuration. Check the router’s documentation or administrator interface if you manage the network. On a shared, school, or workplace network, ask its administrator rather than trying to bypass restrictions.

Fix problems on a single device

When other devices connect but one does not, restart that device and install available operating-system or Wi-Fi driver updates through its normal update settings. On a computer, a disabled wireless adapter or outdated driver can prevent connection; on a phone or tablet, a stale saved network profile is a common possibility.

Check the device’s date and time if it connects to Wi-Fi but has trouble with secure websites or network services. Incorrect time can interfere with some secure connections, though it usually does not explain a failure to see the network at all.

Use network reset options only after simpler checks. Depending on the operating system, a reset may remove saved Wi-Fi networks, passwords, or other network configuration. Read the confirmation screen before proceeding, and make sure you can re-enter the needed network details. Avoid deleting or changing settings you cannot restore.

When the router or internet service is the issue

If every device fails, inspect the router’s power, indicator lights, and cables, then restart the router and any separate modem. If the modem reports no service or the router reports that its internet connection is down, the cause may be a loose connection, an outage, or a service-side problem. Check your provider’s service-status information using mobile data or another connection, or contact the provider.

If the Wi-Fi network name is missing altogether, make sure the router’s wireless function has not been disabled. A router may need configuration or repair if it repeatedly drops all devices, overheats, or fails to broadcast after a restart. Consult its manual or the network administrator before changing advanced settings.

A factory reset is a last resort, not the same as a restart. It can erase the Wi-Fi name and password, provider configuration, and other custom settings. Use it only when the router’s instructions or support recommend it and you have the information required to set it up again.

Common mistakes and useful precautions

Resetting too soon: Restarting preserves settings; a factory reset may remove them.
Confusing Wi-Fi with internet: A device can connect to the router even when the router has no service upstream.
Using an old password: Forget the saved network and reconnect with the current credentials.
Changing many settings at once: Make one change at a time so you can identify what helped and undo changes that do not.
Sharing credentials: Do not post your Wi-Fi password or router administrator password publicly. If you manage the router, use its documented controls to update credentials when appropriate.

Frequently Asked Questions

Why does my device say it cannot connect to this network?
Possible causes include an incorrect or changed password, a weak signal, an incompatible Wi-Fi setting, or a temporary device or router problem. Try reconnecting near the router, forgetting the saved network, and testing another device.

Why am I connected to Wi-Fi but have no internet?
Your device may have reached the router, while the router has lost its connection to the modem or provider. Check the router’s internet status and cables, restart the modem and router, and look for a service outage.

Should I press the reset button on my router?
Not for a routine connection problem. A reset button commonly restores factory settings and can erase your network configuration. Try a power restart first, and follow the router’s instructions before performing a factory reset.

Why can one device not connect when others can?
The affected device may have an outdated saved password, disabled Wi-Fi, or a software or adapter issue. Restart it, forget and rejoin the network, and check for normal system or driver updates.

When should I contact my internet provider?
Contact the provider if multiple devices lack internet after you check the cables and restart the equipment, especially if the modem indicates no service or an outage is reported. If only one device fails, investigate that device first.
