Thanks! Initially that was the case, the LG TV did lose the WiFi connection (until a few days ago it had an Ethernet connection). I got the network set up, did a speed test and also tested some of the other apps. They were working fine. I got results from the Speedtest app and could load content from Netflix and Amazon.
Our servers did experience a brief delay in serving up connections around the time you made this post. If you open up the Tablo app now, do you have the same issue?
