i constantly get a black screen that tells me i am NOT on my home wifi network so I cannot watch a channel that is part of my channel package-on wired and wireless devices. I have internet access when this happens, it is annoying, i have called about this numerous times and no one acknowledges that this is a common issue-in fact, I often here that they never heard of this, yet there are literally thousands of complaints about this in forums and on the internet.

The only thing I ever see here is that Comcast is aware of this and is working on it-going back over a year!!!
