Hp 3772 printer won't connect to wifi

[HoosierMama247]

My HP DeskJet 3772 will NOT connect to my internet. The error says "Can't connect to 5 GHz internet. Must be 2.4 GHz internet"

I have 2 signals from my router... a 5 GHz and. 2.4 GHz, but it still won't connect.

Will a cord connecting my printer to the computer directly fix my issues?

Hi @HoosierMama247,

Welcome to the HP Support Community. 

I understand that you are facing issues with connectivity. I'd like to help!

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details: 

• Have you attempted to restart the computer, printer and router?
• Did you check the network and printer connection status?

While you respond to that, here's what you need to do:

Step 1: Restart the computer, printer, and router

Restart the computer, printer, and router to resolve any error states present during the printer setup.

   NOTE:

The following steps temporarily disconnect network and Internet connections, and require restarting your computer. Complete any tasks or downloads in progress before continuing.

Disconnect the power cord from the router.

Turn off the printer.

Close all running programs on your computer, including the HP software installation window, then shut down the computer.

Reconnect the power cord to the router, then wait for the Internet activity light to display a normal connected status.

Turn on the printer.

Turn on the computer.

Try installing the HP driver and software again.

Step 2: Check the network and printer connection status

Make sure your network is working correctly and that the printer is ready for the network setup.

Confirm that the printer is ready for the network setup.

Wireless network connection: On the printer, open the Wireless network or Settings menu to make sure the wireless signal is turned on. Make sure the light next to the Wireless icon is either on and steady, or blinking.

Wired network connection: Check that the cable is connected to the printer Ethernet port and to an available port on the router. The green link light should be steady, and the orange activity light should blink when the cable is connected.

Make sure your printer is not connected to a guest or host network, such as those networks found in schools, hotels, or home networks that allow guest logins. For more information see Can't Print on a Guest or Host Network.

If you have a dual band router, make sure it is set to the 2.4 GHz band. If your router is set to the 5 GHz band, the printer cannot connect to the network.

On the computer, mouse over the network icon in the notification area to view the network name and status of the connection.

   NOTE:

If you are using a Virtual Private Network (VPN), disconnect from it when installing the printer.

If the network shown is not yours (for instance, if you connected to a neighbor's or guest network), you must reconnect to your own network to complete the printer setup.

If the network signal strength is weak, move the computer and printer closer to the router, position the devices away from large metal objects such as bookcases, and move away from devices that emit radio signals such as microwaves and cordless phones.

If the network status is not connected, confirm that your network is working correctly, then check the status again. Make sure a checkmark displays next to the network name.

If an Airplane icon displays, click the icon, slide the Airplane mode slider to Off, then connect to your wireless network.

Try installing the HP driver and software again.

Step 3: Manually connect the printer to your network (wireless connections only)

Try connecting the printer to your network manually so that the HP installer can find the printer. Use the Wireless Setup Wizard if you have a touch or text-based control panel, or try Wi-Fi Protected Setup (WPS). After connecting, try installing the HP driver and software again.
