Why your printer won’t connect to WiFi after a router change and how to fix it

After changing your WiFi router, your printer often won’t connect because it still tries to use the old network name (SSID) and password. To fix this, update your printer’s WiFi settings with the new network name and password. If that doesn’t work, resetting the printer’s network settings usually resolves the issue.

Why did my printer lose WiFi connection after changing the router?

Your new router likely uses a different network name (SSID) and password than the previous one. Your printer keeps the old network details saved and won’t switch to the new ones on its own. This means it can’t find or authenticate with your new WiFi network, so it won’t connect. That’s why it worked before but won’t after you changed routers.

What network details do I need to reconnect my printer?

To reconnect, you’ll need the new WiFi network name (SSID) and password. These are usually printed on a label on the router or included in the setup guide from your internet service provider. If you changed these details yourself during setup, use those updated credentials. Without the correct SSID and password, your printer can’t join the wireless network.

How do I update my printer’s WiFi settings to connect to the new router?

Most printers let you update WiFi settings through their control panel or touchscreen. Follow these steps:

1. On your printer, open the Settings or Network menu.
2. Select the Wireless Setup Wizard or WiFi setup option.
3. The printer will scan for available networks—choose your new router’s SSID.
4. Enter the new WiFi password exactly, including capitalization.
5. Confirm and save your settings.

For example, on HP printers, you press the Wireless button then select "Wireless Setup Wizard." Epson printers often have a WiFi Setup option in the Network menu. If your printer lacks a screen, you might need to use WPS (WiFi Protected Setup): press the WPS button on your router, then press the WPS button on your printer within two minutes to connect without typing a password.

What if updating the WiFi settings doesn’t work? How do I reset the printer’s network settings?

If entering the new WiFi credentials doesn’t connect your printer, try resetting its network settings:

1. Find the option to restore network settings or reset wireless settings in your printer’s menu. This is often under Setup > Network > Restore Network Defaults.
2. Confirm the reset.
3. After resetting, run the wireless setup again to connect to your new router.

Resetting returns the printer’s network configuration to factory defaults and usually fixes deeper connection problems caused by the router change.

How can I check if the printer is properly connected and ready to print?

After updating or resetting your printer’s WiFi settings, check the connection:

• Use the printer’s control panel to print a network configuration or status page. This page shows the current SSID, connection status, and IP address.

• On many printers, find this under Setup > Reports > Network Configuration.

• The IP address should be a private address assigned by your router, like 192.168.x.x or 10.x.x.x. If it shows "0.0.0.0" or "Disconnected," the printer isn’t connected.

• Try printing a test page from your computer or phone to confirm the printer communicates properly.

If the printer is connected but won’t print, make sure your computer is on the same WiFi network and that the printer is selected in your print settings.

How to avoid connection problems after future router changes

To reduce connection issues after changing routers:

• Use the same network name (SSID) and password on your new router as on the old one when possible. This helps devices reconnect automatically.

• Keep your network name and password recorded so you can update devices quickly.

• Assign a static IP address to your printer through the router’s settings to avoid IP conflicts.

• If WiFi connections remain unstable, consider a wired Ethernet connection or a WiFi extender near the printer.

• Regularly update your printer’s firmware to keep its networking features current and prevent compatibility problems.

Conclusion

If your printer won’t connect after changing your router, start by updating its WiFi settings with the new network name and password. If that doesn’t fix it, reset the printer’s network settings and reconnect. Always verify the connection by printing a network status page. Using the same network name and password or saving your credentials can help avoid this in the future.
