A wireless printer can be convenient until it suddenly refuses to connect to Wi-Fi. You may see a connection error on the printer, the computer may fail to find the device, or the printer may connect briefly and then disappear from the network.
If you're dealing with a printer not connecting to WiFi, the problem is usually related to the wireless network, incorrect Wi-Fi credentials, printer configuration, device discovery, or printer software.
The good news is that many wireless connection problems can be checked with a few practical steps. This guide explains how to identify the problem and work through printer Wi-Fi troubleshooting without changing settings unnecessarily.
A printer may fail to connect to Wi-Fi for several reasons. Common causes include:
Before making changes, it helps to determine exactly where the connection is failing.
Not every wireless printer problem is the same. Identifying the symptom can help you choose the right troubleshooting step.
If your printer does not display your wireless network when you search for available networks, the problem may be related to the printer's wireless settings, network compatibility, signal strength, or router configuration. Check that Wi-Fi is enabled on the printer and that the router is operating normally.
If your network appears on the printer but the connection fails, verify the Wi-Fi password carefully. A small typing mistake can prevent the printer from joining the network. If you recently changed your router, Wi-Fi name, or password, the printer may still be configured with the old network information.
This is a different type of problem. The printer may already have a working wireless connection, while the computer is connected to another network or cannot discover the printer. Check the network connection on both devices before reinstalling the printer.
Repeated disconnections can point to weak wireless coverage, network configuration problems, interference, router changes, or printer-specific connectivity issues. Start with the basic connection checks before changing advanced network settings.
A few simple checks can prevent unnecessary troubleshooting.
Look at the printer's display or wireless indicator. Depending on the model, the printer may show a Wi-Fi icon, network name, connection status, or wireless error. If your printer provides a network status or wireless test, use it to determine whether the printer is actually connected.
Make sure the printer is attempting to connect to the correct Wi-Fi network. This is especially important if your home or office has:
A computer and printer may both have Wi-Fi enabled while still being connected to different networks.
If the password was recently changed, the printer may continue trying to use the old credentials. Reconnect the printer using the current Wi-Fi password rather than repeatedly retrying the old connection.
For wireless printing, the computer and printer generally need to be able to communicate over the same network. Microsoft specifically recommends checking that the printer and Windows device are connected to the same Wi-Fi network when troubleshooting wireless printer problems.
Work through these steps in order. Test the printer after each major change so you know which step resolved the problem.
Turn the printer off and unplug it from power. Wait about 30 seconds, reconnect it, and turn it back on. A restart can clear a temporary communication problem and allow the printer to establish a fresh network connection. Microsoft also recommends power cycling the printer as an initial troubleshooting step.
If other devices are also having trouble connecting to the network, restart your router. Allow the router to finish starting before attempting to reconnect the printer. HP's troubleshooting guidance also recommends restarting the router when diagnosing a printer Wi-Fi connection problem.
Your printer may be connected correctly while the computer or phone has an outdated network connection. Restart the device you are using to print and then check whether the printer appears again.
If the printer has lost its wireless connection, open its network or wireless settings. The exact menu names vary by manufacturer and model, but the process generally involves:
For model-specific instructions, use the documentation or support information provided by the printer manufacturer.
Think about whether anything changed before the problem started. For example:
If the network has changed, the printer may need to be configured again.
A weak wireless signal can make a printer connection unreliable. If possible, temporarily move the printer closer to the router and test the connection.
HP recommends checking printer and network placement as part of wireless connection troubleshooting. If the connection becomes stable after moving the printer, wireless coverage may be contributing to the problem.
A wireless connection problem can sometimes be confused with a printer software problem. If the printer connects to Wi-Fi but the computer cannot communicate with it, check whether the appropriate printer software or driver is installed.
For Windows, Microsoft recommends using compatible and current printer drivers when troubleshooting printer connection and compatibility problems. When downloading drivers, use the printer manufacturer's official support source rather than an unfamiliar third-party driver website.
If the printer is connected to the network but your computer still cannot communicate with it, removing and adding the printer again may refresh its configuration.
On Windows, go to: Settings → Bluetooth & devices → Printers & scanners. Select the printer and remove it. Then use the option to add a printer again.
Microsoft recommends removing and reinstalling a printer when connection troubleshooting does not resolve the problem.
This situation can be confusing because the printer may show a successful Wi-Fi connection while the computer says no printer was found. Check the following:
If the printer previously worked and stopped appearing after a network change, removing and adding the printer again may refresh its configuration.
A printer that connects successfully but repeatedly disconnects needs a slightly different approach. Start by checking:
If other devices also lose Wi-Fi, the problem may involve the network rather than the printer itself. If only the printer disconnects, focus on the printer's wireless configuration and model-specific troubleshooting instructions.
The printer may have incorrect credentials, disabled wireless functionality, weak signal strength, or network compatibility issues.
The printer may be connected to the network while the computer has an incorrect printer configuration or cannot discover the device.
The printer may not have been added correctly, or the computer and printer may not be communicating across the network.
The printer may still contain the previous network name or password. Reconfigure the wireless connection using the new network details.
This can indicate a device-specific configuration, driver, software, or network discovery problem.
Basic troubleshooting is often enough for straightforward connection problems. However, additional assistance may be useful when:
Professional printer troubleshooting can help separate a printer configuration issue from a computer or network problem.
A few habits can make future wireless printer troubleshooting easier:
The goal is not simply to reconnect the printer once. It is to identify why the wireless printer connection failed and correct the underlying configuration where possible.
