How to fix a printer that wont connect to wifi

If a printer used to join Wi‑Fi and now won’t, start by checking that it’s trying to connect to the right network name and password. If that’s right, reconnect the printer to the network, then reset only the printer’s network settings if the connection is still stuck. If it still fails, use the clues below to tell whether the printer, the router, or the device sending the print job is the problem.

Symptom

This usually shows up as a printer that says it’s offline, keeps blinking on Wi‑Fi, or no longer appears on the network even though it used to work. Sometimes the printer still powers on normally, but your computer or phone can’t find it when you try to print.

If the problem started right after a router change, password change, power outage, or a new mesh system, the printer may still be trying to join the old network name or using stale connection details.

Before you start

• Check the exact Wi‑Fi name and password you want the printer to use.
• Make sure you can get to the printer’s display or network menu, or the companion app if that model uses one.
• If the printer has been moved, put it close enough to the router for setup.
• If the router was changed recently, confirm whether the printer should be joining a guest network, a main home network, or a separate 2.4 GHz network.

If the printer can’t see any wireless networks at all, that points more toward the printer or its placement. If it sees networks but not yours, the network name, password, or band is more likely. If it says connected but the computer or phone still can’t print, the problem may be the router or the sending device rather than the printer itself.

Check the printer against the router first

Start with the safest check: make sure the printer is trying to join the correct Wi‑Fi network name and password. Printers often remember an old network name, and after a router replacement or settings change, the saved network may no longer match what’s broadcasting now.

If your router uses separate bands, confirm that the printer supports the one you’re trying to use. Many printers work on 2.4 GHz only, while some routers combine bands under one name or hide the slower band behind a different setting. If the printer can’t see your network at all, or it sees it but won’t connect, band mismatch is one of the first things to check.

To narrow down the fault quickly:

• If the printer cannot see any Wi‑Fi networks, the printer’s wireless function or placement may be the issue.
• If the printer sees networks but refuses yours, the network name, password, or band is more likely.
• If the printer says connected but your computer still can’t print, the problem may be the sending device or the router’s local network settings.

Forget the old network and reconnect the printer

Use the printer’s network menu or companion app to forget the old network and join the current one again. This is the cleanest reversible fix because it replaces stale Wi‑Fi details without erasing the rest of the printer’s settings.

1. On the printer, open the Wi‑Fi or network settings menu.
2. Find the saved network and choose the option to forget, remove, disconnect, or delete that network entry.
3. Scan for available networks again.
4. Select the correct Wi‑Fi name.
5. Enter the password carefully, including upper- and lowercase letters if your network uses them.
6. Wait for the printer to show a connected status before you try to print.

If the printer accepts the password but still won’t connect, stop repeating the same join attempt and move on to a network-only reset. If the printer reconnects here, you do not need to wipe anything else.

Reset only the printer’s network settings if needed

A network reset clears saved Wi‑Fi details and similar wireless settings, but it usually does not wipe the whole printer. That makes it safer than a full factory reset for most cases, because the rest of the printer’s setup stays intact.

Use this step when the printer keeps trying the wrong network, shows a stuck wireless state, or won’t accept a network it should normally join. The exact menu label varies by model, so look in the printer’s network or setup menu for something like wireless reset, network reset, or reset network settings.

1. Open the printer’s settings or network menu.
2. Choose the network reset option, not a full reset unless the manual says that is the next step.
3. Confirm the reset.
4. After the printer restarts, go back to wireless setup and join the correct network again.

If the printer still won’t connect after the network reset, the next likely causes are router compatibility, signal strength, or a model limitation. At that point, check the manual or support page for the exact wireless setup steps for your model.

Verify that the printer is online before you print again

Don’t try another print job until the printer shows that it is online and joined to the network. Look for a solid Wi‑Fi light, a connected message on the display, or a network status page that shows an IP address. Many models can print a network configuration page from the control panel.

Then check the device you plan to print from. Make sure it’s on the same home network, not guest Wi‑Fi or cellular data, and try a small test print. If the printer appears online but the job still won’t send, the problem may be with the computer or phone sending the job, not the printer itself.

A good result is simple: the printer shows connected, the network report shows an address on your home network, and a test page prints without the printer dropping off again.

When this points to a different problem

Sometimes the printer is fine and the network around it is not. A router outage, guest network, access control setting, or weak signal can all stop a printer from joining or staying connected. If the printer is far from the router, walls or interference can be enough to make the connection unstable.

A few common edge cases:

• The router is down or rebooting.
• The printer is on a guest network that blocks local device discovery.
• The router is set to allow only approved devices.
• The printer only supports 2.4 GHz, but the network you’re trying uses a 5 GHz-only setup.
• The signal is too weak where the printer sits.

If the printer joins briefly and then drops off again, the signal or router settings are usually more likely than a bad printer setup.

How to keep it from dropping off again

Keep the Wi‑Fi name and password stable once the printer is working. Changing the router name or security settings later means you may need to set up the printer again.

A few practical habits help:

• Place the router where the printer can get a steady signal.
• Avoid hiding the 2.4 GHz band if the printer needs it.
• Keep the printer on your main home network, not a guest network.
• After router changes, check the printer first before assuming the printer failed.
• If the printer supports both Wi‑Fi and Ethernet, choose one connection method and leave it there unless you have a reason to change it.

If the network must change, reconnect the printer right away so it doesn’t sit offline for days.

Conclusion

If the printer still won’t join Wi‑Fi after the network-only reset, check the exact model’s manual or support page for the supported bands and the next setup step.
