Why isn't Fox sports Southeast coming in online even when hooked to home wifi and it comes in on TV?
If the programming is on the cable box, but not online or on the app, there was likely a blackout restriction attached to the program by the league or network.
I also wanted to add that the channels, Fox Sports etc., have exclusive streaming rights on some content.
In many cases, even if it is not permitted to be streamed on our Spectrum TV App/Website, the networks own App will have that content available to stream. You should have access to that using your Spectrum ID and password, just like with the other participating channel apps.
You can see a list of those here: http://bit.ly/2TkQqZ8
