Connectivity to the router C7800

[Tio1]

Yes, where I live I have a dish satellite from AT&T. I would like to find out if the router C7800 is compatible, to connect to the router.

The C7800 is a coaxial modem device. Its not capable of connecting with dish service. 

You could get a router only device and connec to your current gateway. There'd be a few settings to change but it should work.

Ok thanks
What about the model C1900 cable modem router it could help me about the connection?
Thank you again.

Not sure what you mean by "It could help me about the connection"?

A coaxial modem connects to coax isp like xfinity/cox/spectrum.

If you've already got a gateway from your dish services then you'd want just a standard router like the R**** series of routers. 

here's the series:

CM: coaxial modem only

C****: coaxial modem/router

R****: router only models

RAX: AX routers

D****: DSL modem/router devices

EX: extenders

EAX: AX extenders

   "coaxial" is not the important part.  A satellite gizmo might use
coaxial cable, too.  What matters is what's at the other end of that
coaxial cable.  A Netgear model Cxxxx, CAXxxx, or CMxxxx expects to talk
to a cable-TV ISP, not to some satellite gizmo.

   Not a Netgear model number.
