Samsung printers are designed to make wireless printing convenient, but sometimes a printer may stop connecting to WiFi or fail to communicate with a computer or mobile device. A Samsung printer may have difficulty connecting because of an incorrect WiFi password, weak wireless signal, router settings, outdated software, network changes, or incorrect printer configuration.
If your Samsung printer is not connecting to WiFi, you can usually resolve the problem by checking the wireless network, restarting the devices, reconnecting the printer, and correcting the printer or computer settings.
Check the Samsung Printer Power
Start by checking whether the Samsung printer is powered on correctly. Look at the printer control panel and make sure the display or indicator lights show that the printer is ready.
If the printer does not respond, turn it off and disconnect the power cable. Wait for a short time and reconnect the cable. Turn the printer back on and allow it to complete its startup process.
A temporary communication problem can sometimes prevent the printer from connecting to the wireless network. Restarting the printer gives the wireless connection a fresh start.
Check Your WiFi Network
Before changing printer settings, make sure your WiFi network is working properly. Connect a phone, laptop, or another device to the same wireless network and check whether it has internet access.
If other devices are also having connection problems, the issue may be related to the router or internet connection rather than the Samsung printer.
Restart the router if necessary. Disconnect the router from power, wait briefly, reconnect it, and allow the wireless network to become available again. Once the network is working, try connecting the Samsung printer again.
Verify the WiFi Password
An incorrect wireless password is one of the common reasons a Samsung printer cannot connect to WiFi.
Check the password carefully before entering it on the printer. WiFi passwords are case-sensitive, so uppercase and lowercase letters must be entered correctly. Also check numbers, special characters, and spaces.
If you recently changed your WiFi password, the printer may still have the old password saved. In that situation, remove the previous wireless configuration and connect the printer using the new password.
Move the Printer Closer to the Router
A weak wireless signal can prevent a Samsung printer from maintaining a stable connection.
If the printer is located far away from the router, move it closer temporarily and try connecting again. Avoid placing the printer behind large furniture, inside a closed cabinet, or near devices that may interfere with wireless communication.
Once the printer successfully connects, you can determine a suitable permanent location where the wireless signal remains strong.
Restart the Samsung Printer and Router
Restarting both the printer and router can resolve temporary network communication problems.
Turn off the Samsung printer and router. Allow both devices to remain off for a short period. Turn the router back on first and wait until the wireless network becomes available. Then turn on the Samsung printer.
After the printer finishes starting, open its wireless settings and try connecting to the WiFi network again.
Reconnect the Samsung Printer to WiFi
If the printer remembers an incorrect or outdated network configuration, reconnecting it to WiFi can help.
Open the wireless or network settings on the Samsung printer. Look for the option that allows you to select a wireless network. Choose your home or office WiFi network from the available networks.
Enter the correct WiFi password and allow the printer to establish the connection. Wait until the printer indicates that it is connected before attempting to print.
Check the Printer Network Settings
Incorrect network settings can prevent a Samsung printer from communicating with your router.
Open the printer's network settings and check whether wireless networking is enabled. Confirm that the printer is configured for the correct wireless network.
If the printer has previously been connected to another router or network, its saved settings may no longer match your current network. Resetting the wireless configuration and setting up the connection again can resolve this type of problem.
Check Whether the Computer Is on the Same WiFi Network
Your Samsung printer and computer normally need to communicate through the same local network.
Check the WiFi connection on your computer and make sure it is connected to the same network selected on the printer. If your computer is connected to a different network, the printer may not appear as available.
This is especially important if your router provides separate wireless networks or guest network access. A computer connected to a guest network may not be able to communicate properly with devices connected to the main network.
Check the Printer in Windows Settings
If the Samsung printer is connected to WiFi but your Windows computer cannot print, check the printer settings.
Open the Windows printer settings and locate your Samsung printer. Check whether Windows shows it as available or offline.
If the printer is listed as offline, verify the network connection first. You can also remove the printer from Windows and add it again after confirming that the printer is connected to WiFi.
Adding the printer again can help Windows establish a fresh connection.
Clear the Print Queue
A stuck print job can sometimes make a wireless printer appear unavailable.
Open the printer queue on your computer and check for documents that are waiting to print. Cancel old or failed documents and try sending a new test document.
If the queue remains stuck, restarting the Windows Print Spooler service can help refresh the printing system. After clearing the queue, try printing again.
Update or Reinstall the Samsung Printer Driver
An outdated, damaged, or incompatible printer driver can cause communication problems between the computer and Samsung printer.
Check the installed Samsung printer software on your computer. If the driver is outdated, install the appropriate driver for your printer model and operating system.
If the existing driver appears damaged, removing the printer and its related software before reinstalling the correct driver may provide a cleaner connection.
After reinstalling the driver, restart the computer and try adding the Samsung printer again.
Check Your Router Settings
Some router configurations can interfere with printer connections.
Check whether the router is working normally and whether other devices can communicate with each other on the network. If your router has recently been replaced or its settings have changed, the printer may need to be configured again.
Some Samsung printer models may also have specific wireless compatibility requirements. If the printer does not detect your network, check the wireless settings supported by your particular printer model.
Check the WiFi Frequency
Some wireless printers may have limitations regarding supported WiFi frequencies or network configurations.
If your router provides separate wireless networks, try connecting the Samsung printer to the network that is compatible with your printer model. Keep the printer and computer connected to a network that allows communication between devices.
If the printer cannot see your WiFi network at all, checking the router's wireless configuration can help identify the cause.
Disable a VPN Temporarily
A VPN on your computer can sometimes interfere with communication with local network devices.
If the Samsung printer connects to WiFi but cannot be detected by the computer, temporarily disconnect the VPN and try searching for the printer again.
If the printer becomes available after disconnecting the VPN, the VPN configuration may be affecting local network communication.
Check Firewall and Security Software
Computer security software can occasionally block printer communication over a local network.
If your Samsung printer is connected to WiFi but cannot be found by the computer, check your firewall and security settings. Make sure the printer software is allowed to communicate through the local network.
Avoid permanently disabling security protection. Instead, use the appropriate trusted-device or application permissions provided by your security software.
Remove and Add the Samsung Printer Again
If the printer still does not connect correctly, removing it from the computer and adding it again can refresh the connection.
First, confirm that the printer is connected to the correct WiFi network. Then remove the existing Samsung printer from the computer's printer settings.
Restart the computer and add the printer again. Windows may automatically detect the printer on the network. If it does not, use the available printer-addition options and follow the setup instructions for your model.
Reset the Samsung Printer Network Settings
If the Samsung printer continues to use incorrect wireless information, resetting its network settings may help.
A network reset removes the saved wireless configuration and allows you to configure the printer again. After resetting the network settings, select your WiFi network and enter the current password.
Keep in mind that the exact network-reset procedure can vary between Samsung printer models, so use the instructions applicable to your specific printer.
Test the Wireless Connection
After reconnecting the Samsung printer to WiFi, perform a test print.
Check whether the printer appears as available on your computer and send a small document to the printer. If the document prints successfully, the wireless connection is working.
If the printer connects but repeatedly loses the connection, investigate the WiFi signal, router placement, network congestion, and printer location.
Samsung Printer Not Connecting to WiFi After Changing the Router
If you recently changed your router, internet provider, WiFi name, or WiFi password, the Samsung printer may still contain the old network information.
In this situation, reconnect the printer to the new wireless network. The printer may need to forget the previous network before it can connect to the new one.
Also make sure your computer or mobile device is connected to the same new network when you test printing.
Samsung Printer WiFi Connection Keeps Dropping
A Samsung printer that connects and then disconnects repeatedly may be experiencing weak wireless coverage or network instability.
Move the printer closer to the router and check whether the connection improves. Restart the router and printer and make sure the network is operating normally.
If the problem continues, check for firmware, driver, or router configuration issues that could affect wireless communication.
When the Samsung Printer Still Cannot Connect to WiFi
If none of these steps resolves the problem, check the printer's display for error messages or network warnings. Write down the exact message because it may indicate whether the issue is related to authentication, wireless configuration, network communication, or the printer itself.
You can also test the printer with another computer or mobile device. If the printer works with another device, the problem may be related to the original computer's settings or software.
If the printer cannot connect to any device or network, review the network configuration and model-specific setup instructions.
Conclusion
A Samsung printer that is not connecting to WiFi can often be fixed by checking the wireless network, verifying the WiFi password, restarting the printer and router, improving the wireless signal, reconnecting the printer, and checking computer settings. Driver problems, firewall restrictions, outdated configurations, and changes to the router can also affect wireless printing.
Start with the basic network and power checks before changing advanced settings. Once the Samsung printer successfully connects to WiFi, test it with a small document to confirm that the wireless connection and printing functions are working correctly.
