Steps

Goal: Confirm the symptom, rule out 2.4 GHz and password issues, then check placement, router settings, and power-cycle.

  • On the printer display or control panel, look for a Wi‑Fi icon with an X, “Connection failed,” or “Unable to connect.”
  • Good: The printer shows a Wi‑Fi error or never joins—connection problem. Proceed to Check 2.4 GHz and password.
  • Bad: The printer says “Connected” but the computer cannot find it—different issue (driver, queue, or network discovery). See Fix a printer that will not print.

Check 2.4 GHz and password

Goal: Rule out band and password issues—the two most common causes.

  • Log into your router (often 192.168.1.1 or 192.168.0.1). Confirm 2.4 GHz is enabled. If both 2.4 and 5 GHz use the same SSID, use a separate 2.4 GHz network name or temporarily disable 5 GHz during setup.
  • Confirm the password for the 2.4 GHz network. Passwords are case-sensitive. Connect another device (phone or laptop) to the same 2.4 GHz network with that password to confirm it works.
  • Good: 2.4 GHz is on and the password is correct. Proceed to Check placement and power-cycle.
  • Bad: 2.4 GHz was off or the password was wrong—fix and retry.

Check placement and power-cycle

Goal: Rule out weak signal and stuck state.

  • Move a phone or laptop to the printer location. Check Wi‑Fi signal strength (bars or RSSI). If the signal is weak or absent, use a Wi‑Fi extender or move the printer closer to the router.
  • Power off the router (and modem if separate), wait 60 seconds, power on. Turn off the printer, unplug it for 30 seconds, plug it back in and turn it on. Retry the Wi‑Fi setup.
  • Good: Usable signal and power-cycle done. Proceed to Router settings.
  • Bad: Weak signal or power-cycle not done—fix and retry.

Router settings

Goal: Check settings that can block the printer from joining.

  • Log into the router. Disable AP isolation for the 2.4 GHz network. If MAC filtering is on, add the printer MAC address to the allow list or disable it. If the SSID is hidden, broadcast it during setup.
  • Good: AP isolation is off and no blocking rules for the printer. Proceed to run the printer Wi‑Fi setup wizard.
  • Bad: Settings were blocking—fix and retry. If you cannot change settings, run the setup wizard and try WPS if available.

Run the printer Wi‑Fi setup wizard

Goal: Join the printer to the network using the correct procedure.

  • Use the printer control panel or LCD to start the Wi‑Fi setup wizard. Select your 2.4 GHz network and enter the password. If the printer previously connected and then stopped, clear saved networks (forget network or reset Wi‑Fi settings) and run the wizard again.
  • If both the printer and router support WPS, press the WPS button on the router, then start WPS on the printer within two minutes.
  • Good: The printer connects and shows “Connected” or similar.
  • Bad: The printer still will not connect—call the manufacturer if other devices connect to the same network.

When to get help

Call the manufacturer if:

  • You have tried 2.4 GHz, correct password, placement, power-cycle, router settings, and the setup wizard and the printer still will not connect.
  • Other devices connect to the same network but the printer does not—the printer Wi‑Fi hardware may have failed.

Verification

  • The printer display shows “Connected” or a Wi‑Fi icon without an X.
  • The printer appears in the list of available printers on your computer.
  • A test page prints from the computer.
  • No Wi‑Fi error on the printer control panel.

Escalation ladder

Work from the device outward. Stop when the problem is fixed.

  1. Confirm symptom Verify the printer shows a Wi‑Fi error or never joins—not just computer-side issues.
  2. 2.4 GHz and password Confirm 2.4 GHz is enabled and the password is correct for that network.
  3. Placement and power-cycle Check signal at the printer location; power-cycle router and printer.
  4. Router settings Disable AP isolation; check MAC filtering and hidden SSID.
  5. Setup wizard or call a pro Run the printer Wi‑Fi setup wizard again; if still no connection, call the manufacturer.

What to capture if you need help

Before calling support or posting for help, have these ready. It speeds everything up.

  • Printer brand and model
  • Whether 2.4 GHz is enabled and SSID name
  • Signal strength at printer location (if measurable)
  • Router settings (AP isolation, MAC filtering, hidden SSID)
  • Steps already tried

Does the printer show a Wi‑Fi error or never join?

On the printer display, look for "Connection failed," "Unable to connect," or a Wi‑Fi icon with an X. Confirm it is a connection problem, not just the computer cannot find the printer.

Check the printer display. Good: printer shows a Wi‑Fi error or never joins—connection problem. Bad: printer says "Connected" but the computer cannot print—different issue (driver, queue, or network discovery).

Yes No (different issue)

Is 2.4 GHz enabled and are you using that network?

Most printers only support 2.4 GHz. If the router uses one SSID for both bands, the printer may fail.

Log into the router. Confirm 2.4 GHz is enabled. Use a separate 2.4 GHz SSID or temporarily disable 5 GHz during setup. Good: 2.4 GHz is on and you are connecting to it. Bad: 2.4 GHz is off or you are on 5 GHz—enable 2.4 GHz and retry.

Yes No

You can change your answer later.

Is the Wi‑Fi password correct?

Passwords are case-sensitive. Confirm with another device on the same 2.4 GHz network.

Re-enter the password. Check for extra spaces or wrong characters. Connect a phone or laptop to the same 2.4 GHz network with that password to confirm it works. Good: password is correct. Bad: password is wrong—get the correct one and retry.

Yes No

You can change your answer later.

Is there usable signal at the printer location?

Weak or no signal at the printer will prevent connection.

Move a phone or laptop to the printer location. Check signal strength (bars or RSSI). Good: usable signal. Bad: weak or no signal—use a Wi‑Fi extender or move the printer closer to the router.

Yes No

You can change your answer later.

Have you power-cycled the router and printer?

Power-cycle clears stuck state on both devices.

Power off router (and modem if separate), wait 60 seconds, power on. Unplug printer for 30 seconds, plug back in, turn on. Retry setup. Good: power-cycle done, retry. Bad: not done—do it and retry.

Yes No

You can change your answer later.

Apply the fix and retry

Follow the fix in the previous step (enable 2.4 GHz, correct password, improve signal, or power-cycle). Retry the connection. If the problem continues, return to the start of this guide.

Done

Are AP isolation, MAC filtering, or hidden SSID blocking the printer?

AP isolation and MAC filtering can block devices. Hidden SSID may not work with some printers.

Log into the router. Disable AP isolation for 2.4 GHz. If MAC filtering is on, add the printer MAC or disable it. If SSID is hidden, broadcast it during setup. Good: settings fixed. Bad: cannot change or unsure—run setup wizard again.

Are router settings blocking the printer?

You can change your answer later.

Run setup wizard and retry

Run the printer Wi‑Fi setup wizard from the control panel. Clear saved networks if the printer previously connected. Try WPS if both router and printer support it. If it still fails and other devices connect, the printer Wi‑Fi hardware may have failed—call the manufacturer.

Done

Different issue — check printer or driver

If the printer says "Connected" but the computer cannot print, the issue is driver, queue, or network discovery—see fix-printer-will-not-print. If the printer never connects, follow this guide from the start.

Done

Frequently asked questions

Why won't my printer connect to WiFi?
Common causes are 2.4 GHz vs 5 GHz (most printers only support 2.4 GHz), wrong password, weak signal, router settings like AP isolation or MAC filtering, or a stuck printer. Check the band first, then password, placement, and power-cycle.
Do printers need 2.4 GHz or 5 GHz?
Most printers only support 2.4 GHz Wi‑Fi. If your router broadcasts both bands under the same name, the printer may fail to connect. Use a separate 2.4 GHz SSID or temporarily disable 5 GHz during setup.
When should I call a technician for a printer that won't connect to WiFi?
If you have tried 2.4 GHz, correct password, placement, power-cycle, and router settings and it still will not connect, run the printer Wi‑Fi setup wizard again. If the printer never connects and other devices do, the printer Wi‑Fi hardware may have failed—call the manufacturer.
