Why does my printer say it is connected but my computer cannot find it?

This usually happens when your computer and printer are on different network bands, such as the computer on 5 GHz and the printer on 2.4 GHz, or if your router has 'AP Isolation' enabled.

Can I connect my printer to a 5G cellular hotspot?

Yes, but mobile hotspots often have strict device limits and may prevent local device-to-device communication, making printing unreliable.

How do I find my printer's MAC address?

You can find the MAC address printed on a label on the back or bottom of the printer. You can also find it by printing a Network Configuration page from the printer's settings menu.

What should I do if my router does not have separate 2.4 GHz and 5 GHz networks?

You can temporarily disable the 5 GHz band in your router's admin panel during setup. Alternatively, move the printer further away from the router during setup to force it to connect to the longer-range 2.4 GHz band.

Printer Not Connecting to Wi-Fi: Causes and Fixes

Quick answer

To connect your printer to Wi-Fi, ensure it is on a 2.4 GHz network band rather than 5 GHz, disconnect any physical Ethernet cables which disable the wireless radio, and verify your router is not using incompatible WPA3 security. If your printer has an IP address starting with 169.254, restart your router to resolve the DHCP assignment failure.

What this means

If your printer won't connect to Wi-Fi, the hardware isn't broken. It just failed the digital handshake with your router.

A few specific things cause this. Most printers only have a 2.4 GHz receiver. If your router uses dual-band steering to merge the 2.4 GHz and 5 GHz bands under one name, your printer's network card gets confused and fails to connect. Check your printer's IP address. If it starts with 169.254, the printer failed to get an IP address from your router's DHCP server. Also, check the back of the machine. If you have an active Ethernet cable plugged into the physical port, it automatically disables the wireless radio on many models.

Your environment or router settings might also be the culprit. Microwaves, baby monitors, and cordless phones interfere with the 2.4 GHz band, dropping your signal strength below the -70 dBm minimum the printer needs to stay connected. On the router side, newer WPA3 security protocols block older legacy printers. If your network name is hidden, you must manually enter the exact name and security type. Finally, if your Wi-Fi password contains special characters, older printer firmware won't support them, and the connection fails.

Common causes

The printer is too far from the Wi-Fi router.
The router is broadcasting on a 5 GHz frequency, but the printer only supports 2.4 GHz.
The Wi-Fi password or network name (SSID) was entered incorrectly.
The router has security features enabled like MAC address filtering that block new devices.
The printer has an outdated IP address configuration or a temporary network glitch.
The network name (SSID) is hidden, preventing the printer from finding it automatically.

What to check first

1Make sure your Wi-Fi router is turned on and your phone or computer is connected to it.
2Verify that you have the correct Wi-Fi network name (SSID) and password.
3Ensure the printer is within 10 to 15 feet of the router during the initial setup process.

Step-by-step fix

1
Restart your printer and router
Turn off your printer. Unplug your Wi-Fi router from its power source. Wait 30 seconds. Plug the router back in and wait for all its lights to become stable. Turn the printer back on and try to connect again.
Do not press the physical reset button on your router, as this will erase all your network settings.
2
Verify the Wi-Fi frequency band
Many older or budget printers only support 2.4 GHz Wi-Fi networks. If your router combines 2.4 GHz and 5 GHz under one name, log into your router settings and temporarily separate them into two different names, then connect the printer to the 2.4 GHz network.
Changing router settings may temporarily disconnect other smart home devices.
3
Re-enter the Wi-Fi password on the printer
Navigate to the printer's control panel. Go to the Network, Wireless, or Setup menu. Select Wireless Setup Wizard. Choose your network name and carefully type your Wi-Fi password. Remember that passwords are case-sensitive.
4
Reset the printer network settings
Locate the network reset option in your printer's settings menu. This clears old network profiles and IP conflicts. After the reset, run the Wireless Setup Wizard again to configure the connection from scratch.
5
Disable MAC address filtering on your router
Log into your router's administration page using a web browser. Look for Security or Wireless settings. Check if MAC Address Filtering is enabled. If it is, either disable it temporarily or add your printer's MAC address to the allowed list.

When to contact a professional

If your wireless menu is completely frozen or grayed out, your Wi-Fi radio hardware is dead. The same is true if the printer fails to detect any wireless networks at all, even when you place it right next to a working router. Stop troubleshooting. You must never open the printer casing or touch internal electrical components, as this voids your warranty. Call a professional or the manufacturer's support. If you need to check the physical ports on the back of the machine, always unplug the printer from the wall outlet first.
