New Xfinity router, now Samsung ml2525w will not connect

Last week I upagraded to the Voice and Data Modem ARRIS Group, Inc TG3482G Xfinity modem in preperation for a home secuitry install.  Everything EXCEPT one divice is workng.  It's my Samsung ml2525W printer.  I have tried everything that I can find on line to fix.  Uninstalled the printer, factory reset on the printer, disbanded the 2.4 and 5 bands, and nothing works.  

Any suggestions?
