Cannot print to my HP Printer with new Xfinity wifi system

I have a HP LaserJet Pro MFP M225-M226 PCL 6.  My system was working well until I installed the XB8 wifi modem and router. I installed all cables according to the instructions and guides.  I no longer have the ability to print from my PC and remotely from my surface Pro.  I have uninstalled and reinstalled the printer on multiple occasions and no progress has been seen. My printer has an IP address which I have entered into the confirguration process and no progress.  I am at the point where I am about to disconnect this XB8 unit and reinstall my old equipment.  At least I did not have to guess at whether it would work.
