Directv Gemini Receiver - C71KWX Question

[mitchellga]

I am currently a Directv Stream customer.using the Directv Gemini Box when it was branded AT&T. When I go into my account to add more devices, although it shows the AT&T box as my equipment, it is just allowing me the option to add the Gemini Air. Does anyone know if I buy the C71KWX from another source such as Solid Signal if it will work either hardwired to the Internet or wirelessly? Thanks!
