In the list of DVRs, my Series 2 and Series 3 are there. My Bolt keeps appearing and disappearing. It is listed but a different color with an exclamation point and an error message says the Bolt can't be found. I called tech support and they said it was a known software issue. Once day the problem seemed to be fixed, for whatever reason. Then it wasn't. And My Roamio couldn't connect to the internet. Unplugging my Roamio and plugging it back in fixed both problems, but as of last night the Bolt is gone again. Why did my WiFi go out?
