Hi @Troy62,

Welcome to HP Support Community. 

Thank you for posting your query. I will be glad to help you.

I see that you are facing issues with connecting your HP DeskJet 3637 All-In-One Printer to your wi-fi network after changing the router.

Please follow the steps listed below to restore the printer to its network defaults and then reconnect it to the network.

Step 1: Restore the printer to its network defaults.
Press and hold the Wireless button and the Cancel button (X) from the printer control panel together for three seconds.

Step 2: Reconnect the Printer to the network:
1. Press and hold the wireless button on the printer for more than least three seconds to start the WPS Push Button method. 
2. Press the WPS button on your router.
NOTE: The product begins a timer for approximately two minutes while a wireless connection is established. If the printer connects successfully, the light next to the Wireless button glows steady blue.
