Printer will not work after installing a new router

[Mary8182]

We just installed a new router.  Now our wireless printer does not recognize it.

Hi @Mary8182,

I'd like to help!

1. Are you trying to connect your printer to your home network,public network or without a router?
2. What is the status of the wireless light on the printer, steady or blinking?
3.  I would like to know, is your router set to work on 2.4 GHz network or 5 GHz network band?

Meanwhile, Try an RPC and then try and connect the printer

To prepare your printer for a wireless connection, restart the printer, computer, and router.

1. Turn the printer off, and then wait 10 seconds.
2. Disconnect the printer power cord from the printer.
3. Turn off the computer or the device you are trying to print from.
4. Connect the printer power cord to the printer, and then turn on the printer.
5. Disconnect the power cord from your wireless router, and then wait 10 seconds.
6. Reconnect the power cord to the router. Wait until Internet service is restored. Internet service is interrupted while the router is off.
7. Turn on the computer.

Run wireless setup wizard-

1. From the home screen of your printer control panel, touch the Wireless icon .

2. Touch the Setup icon .

3. Touch Restore Network Defaults or Restore Network Settings, and then touch Yes to confirm your selection.

4. After the default network settings are restored, touch the back arrow, touch Wireless Settings, and then touch Wireless Setup Wizard.

   The printer searches for available networks.

5. Touch the name of your wireless network.

6. If your wireless network does not display in the list of wireless networks, touch Enter New Network Name, and then type the name of your wireless network.

   NOTE: 

   Type the exact network name, including any uppercase and lowercase letters.

7. Type the WEP or WPA key (network password), and then touch Done.

   If you do not know your network password, go to Find Your Wireless WEP, WPA, WPA2 Password..

   Once the printer connects to the wireless network, the blue Wireless light on the control panel turns on solid.

Hope this helps! Keep me posted.
