To change your printer's wireless settings—whether you are switching to a new Wi-Fi network, updating a changed password, or assigning a static IP address—you can use the printer's built-in control panel, its companion mobile app, or its Embedded Web Server (EWS) in a browser.
Before making changes, ensure your target Wi-Fi network broadcasts a 2.4 GHz band (most printers do not support 5 GHz-only networks) and keep your new Wi-Fi name (SSID) and case-sensitive password ready.
If your printer has a built-in display screen, you can overwrite the saved wireless settings directly from the setup menu:
1.Open Network Setup:
1 min.
Turn on the printer and tap the Setup (gear icon) or Wireless icon on the control panel, then select Network Setup or Wireless Settings.
Verification: The display shows wireless configuration options including Wireless Setup Wizard and Restore Network Defaults.
2.Run the Wireless Setup Wizard:
1 min.
Tap Wireless Setup Wizard (or Wi-Fi Setup Wizard). The printer will scan for active routers nearby.
Verification: A list of available Wi-Fi network names appears on the screen.
3.Select New Network and Enter Password:
2 min.
Select your new Wi-Fi network name (SSID), type the new security password using the on-screen keyboard, and tap OK or Done.
Verification: The printer's Wi-Fi light stops blinking and stays solid blue or green.
If your printer does not have a screen, clear its saved network profile to put it back into pairing mode, then configure the new settings via your phone:
Restore network defaults on the printer:
HP: Press and hold the Wireless and Cancel buttons together for 3 to 5 seconds until the power light blinks.
Canon: Press and hold the Stop/Reset button until the alarm light flashes 21 times, then release.
Epson: Turn 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: Press Menu > Network > Network Reset > Yes.
Verification: The printer's wireless light begins blinking steadily, confirming old Wi-Fi credentials are wiped.
Apply new settings in the companion app: Connect your phone to your 2.4 GHz Wi-Fi, enable Bluetooth, open HP Smart, Canon PRINT, Epson Smart Panel, or Brother Mobile Connect, tap Add Printer (or +), and follow the prompts to push the new Wi-Fi credentials to the printer.
Verification: The app displays your printer as "Ready" or "Connected" on the new network.
If your printer is already on the network and you want to change advanced wireless settings—such as assigning a Static IP, changing IPv4/IPv6 settings, or switching to Wi-Fi Direct—use a web browser:
Print a Network Configuration Page from your printer's Setup > Reports menu to find its current local IP address (e.g., 192.168.1.120).
Open a web browser on a computer or phone connected to the same Wi-Fi, type that IP address into the address bar, and press Enter.
Log in if prompted (the default PIN/password is usually printed on a sticker inside the cartridge access door).
Click the Network or Networking tab, select Wireless (802.11) or IPv4 Configuration, adjust your network or static IP settings, and click Apply.
Verification: The browser confirms settings are saved, and the printer reconnects using the updated parameters.
