Correct. The building's owners don't allow cable. Either one of the two satellite providers or nothing. Apparently, the
owners don't like Comcast. Or Comcast won't cut them in on the revenue.
This is their response and my response to that:

They're using filters that can malfunction, leaving the "line" open? If so, that it is one stupid part.
More likely, they didn't do what they should have, so the failure is that I noticed a problem and understood what was going on.

I have noticed something like that also. Definitely time to start sniffing can capturing. It would be quite ironic if something
in the network was clamping network activity from the satellite provider. Doubt if anything like that is happening at my ISP,
Sonic, which is one of the best in that and most ways. Perhaps it is borking the router.
