my HP officejet pro 8600 will not connect to my new comcast G954331X modem/router

Hi there @user_7sg1qe Thank you so much for reaching out on our Xfinity Community Forum about your printer issues.  I'll be happy to assist. 

To connect your HP OfficeJet Pro 8600 to your new Comcast G954331X modem/router, follow these steps:

1. Go to the printer's control panel and select the Setup option (often represented by a wrench icon).
2. Choose the Network menu.
3. Select your WiFi network name (SSID). If it's not visible, scroll down and manually enter your network name and password.
4. If it still doesn't connect, print a wireless network test report for troubleshooting.
