how do I switch to different wifi to use X1 apps?

I switched from xfinity internet to a different wifi provider.  now all of my premium channels HBO Showtime Cinemax and X1 apps Netflix Peacock Paramount  no longer work.  is there a way to specify a different wifi provider so I can cotninue to use those items?  for those in similar situations what other platform are you using to get to those apps?
