When you replace your router or change your Wi-Fi name and password, your printer remains locked to the old network credentials and will appear offline until you clear its saved wireless profile and pair it with the new router.
Before connecting to the new router, wipe the old Wi-Fi profile from the printer's memory so it enters active setup mode:
Printers with a Touchscreen: Open Setup (gear icon) or Settings > Network Setup (or General Settings) > Restore Network Defaults (or Reset Network Settings) and confirm Yes.
HP Screenless Printers: Press and hold the Wireless and Cancel buttons simultaneously for 3 to 5 seconds until the power light flashes.
Canon Screenless Printers: Press and hold the Stop/Reset button until the alarm light flashes 21 times, then release.
Epson Screenless Printers: Power off the printer, then press and hold the Wi-Fi and Network Status buttons together while powering it back on until the lights flash alternately.
Brother Printers: Press Menu (or Settings) > Network > Network Reset > Yes.
Verification: The printer's Wi-Fi indicator light begins blinking steadily, confirming it is cleared of old settings and ready for pairing.
Make sure your new router is broadcasting a 2.4 GHz Wi-Fi signal (most printers cannot connect to 5 GHz-only bands), then choose the setup method that matches your printer:
Option A: Touchscreen Setup Wizard
1.Open Wireless Setup Wizard:
1 min.
On the printer's control panel, tap Setup (gear icon) > Network Setup > Wireless Setup Wizard.
Verification: The printer scans the room and displays a list of nearby Wi-Fi network names.
2.Select New Wi-Fi and Enter Password:
2 min.
Tap your new Wi-Fi network name (SSID), type the new password using the on-screen keyboard (case-sensitive), and tap OK or Done.
Verification: The Wi-Fi light stops blinking and turns solid blue or green.
Option B: Companion App Setup (Screenless Models)
1.Connect Phone/PC to the New Wi-Fi:
1 min.
Ensure your smartphone or laptop is connected to your new router's 2.4 GHz Wi-Fi network, and turn on Bluetooth and Location permissions.
Verification: Your device shows an active internet connection on the new network.
2.Pair via Manufacturer App:
2 min.
Open HP Smart, Canon PRINT, Epson Smart Panel, or Brother Mobile Connect, tap Add Printer (or +), and follow the prompts to pass your new Wi-Fi credentials to the printer.
Verification: The app displays your printer as "Ready" or "Connected."
Option C: WPS Push-Button Pairing
1.Press the Printer's Wi-Fi/WPS Button:
Prerequisite: Printer in setup mode.
Press and hold the Wi-Fi / WPS button on the printer for 3 seconds until the wireless light blinks rapidly.
Verification: The printer light flashes quickly to indicate WPS discovery mode.
2.Press the New Router's WPS Button:
Within 2 minutes.
Press the physical WPS button on your new router for 1 to 2 seconds.
Verification: Both the router WPS light and the printer Wi-Fi light stop flashing and turn solid.
Because your new router assigns a new local IP address (for example, changing from 192.168.1.x to 192.168.0.x), your computer's old print queue may point to the wrong address.
Windows 10 / 11: Go to Settings > Bluetooth & devices > Printers & scanners, click your old printer entry and select Remove, then click Add device to re-add it from the new network.
macOS: Go to System Settings > Printers & Scanners, select your old printer, click Remove Printer, then click Add Printer, Scanner, or Fax... to add it fresh via Bonjour/AirPrint.
Verification: Print a test page from your computer; the document prints immediately without stalling in the queue.
