Streaming App / "Home WIFI" / Home TV and Business Internet

I have a home TV account and would like to use the Streaming app on a couple of my TVs as well as my iPad.  However, when I use the app it tells me I need to be on my "Home WIFI" or else I get the TVtoGo channels.  Interestingly, it (very) sporadically works.  It also (more often than not) sporadically doesn't even give me the option to see ABC/CBS/NBC/FOX.  But I digress.  I have a Comcast business Internet account.  Once, long ago, I was able to link the accounts but the last several times I called about this I was just met with confusion and an inability to get me working.  Anyone know of a way to get this done or a workaround to get this done?  At this point it much less of an issue switching services than paying for a service that doesn't work, yes - very frustrated.
