Unable to use wireless printer or gateways/bridges with new D-Link 2750

I have setup a new D-Link modem/router and connected my printer, HP Inkjet 4500, and a Netgear Range Extender WN200RPT. I had no problems with connecting them, but I can not print with any of my computers and the Netgear can not connect to the internet throught the ethernet ports. Verizon wants me to sign up for the Premium support, but all of the equipment worked with my old modem/router. Any ideas?
