AC1600 WiFi cable modem router model C6250

[Hippiechk67]

Hello, 

  This may be a stupid question, but my intrnet provider (AT&T) is not on the compatibility list.  Does this mean this router won't work for me?  Thanks for any help given..

The C6250 is a coax modem. Att either has dsl or fibre. So it won't work those installations.
