This is just for information to other users and Tablo David:
Last nite about 8 I turned on my Mi Box (wireless) to watch a recorded show on Tablo in my office, and behold it could NOT find Tablo. (I have not had any problems with Tablo for over 6 months) I did a restart on Mi and still no Tablo - tried the iPad, same result. Went into the bedroom and tried Roku (wireless) with the same result. Went out to the family room where my wife was watching a recorded movie on Tablo!!?? This Roku is hard wired to the extended network Airport Extreme and the Tablo is also hard wired to the same Airport Extreme. Then she finished the movie and exited Tablo. Then I tried the Roku and it could not find Tablo and the Roku is blinking - Tablo has been solid blue up to this point. So I unpluged Tablo and after a min I plugged it back in and behold the blinking Tablo - let it blink for about 5 min, then repeated the process. Then I quickly pushed the little button on the back and the blinking was a little different but settled into the constant blink.
After having a few choice words with Tablo, I went to 192.168.0.1 and sure enough Tablo was offline. So I opened Airport Utility and three of the Airport Extremes had green lights and the one in the family room was yellow - so I went around and looked at each of them and they were all Green?? So Tablo is still blinking and I decided to unplug Tablo and the family room airport. After a min I plugged the airport back in and waited for it to come up green, then I plugged Tablo in and it did the std start up and then turned solid blue.
Waaallaaaa, everything works again. Who can explain this to me?
