The infrastructure I'm on precludes me getting PRISM IPTV. My DSL service has been consistent; I'm configured for 10 mb/sec, I get 9 mb/sec out at the NID (network interface device) on my house, and drop another megabit of speed in my internal wiring, which means I need to replace that.
My modem does require an occasional reset (about once a week) because it will drop down to about 4 mb/sec. After the reset, I go back to the faster speeds.
I'm getting some rain fade on my Direct TV service right now. That happens. I don't like it, but it goes with the technology.
