Arggghhh...Kiss of death!
A few days ago, I "bragged" that we have not had any serious problems with our Gateway ever since we got it (back in November). I made a specific mention that I had not rebooted my Gateway box - ever!
Well, guess what? I can't say that anymore. The other night both of our TVs (portals) showed black screens, for any live TV channel, and for recorded shows it showed a black screen with an empty progress bar at the bottom of the screen. Trying other recorded shows and channels didn't solve anything. My wife (who was in her TV room) shouted that she was having problems. Her symptoms looked identical to the one on the TV I was watching at the time. I went to another TV which is just connected to cable (with a Motorola PVR). That TV was playing everything normally.
I went into the Diagnostics screen, and my Portal showed a LAN status of "Failed to connect to DNS" That was the only thing in red, and the only thing that looked "unusual" (but I'm not an expert in this screen - don't go there very often). So, I tried "Reconnect to LAN". After a minute or so, it was still in a "failed" state. Then tried rebooting the portal. No change. Then tried the "reconnect to LAN" on the other portal. No change. Then tried rebooting that portal. No change.
SO, I looked at the Gateway status, and in the "Private WAN Status" area it said "Failed to connect to Router". I tried reconnecting, but that didn't change anything. So, then I tried rebooting the Gateway. I even went and watched the lights on the Gateway box (something I had never done before). After it rebooted, it still seemed like the problem was there. But...
I went to one of the TVs, and changed the channel. Poof! I got a picture. Tried a recorded program, and it was okay too. Went to the other TV, and it was working fine.
So, if I had to guess, rebooting the Gateway box is what it fixed it.
All of this probably took me about 15-20 minutes. So, I don't know if things would have fixed themselves, if I would have just left everything alone (but I'm having my suspicions that it wouldn't have).
So, it looks like I had some sort of Gateway problem - my first "serious one", that I know of. There goes my perfect record!!
By the way, I just now looked at the diagnostic screens, and the Gateway screen has that same "Failed to connect to Router" message?? But my TV and Gateway functions all appear to be working normally??? Maybe this isn't important? Maybe it's always like this? Confused.
I tried to be very descriptive in this message in the hope that it spurs some sort of explanation, or problem resolution. Sorry for the length of the note.
