thunderbird sometimes seems to "turn off" the internet connection when sending.
Win 8.1 computer, wireless connection. Sometimes we can get the email to send by manually disconnecting then reconnecting. Other comuters do not experience any internet outage.

Thunderbird has no facility to turn off your Internet connection.
Thunderbird will go offline if your computer loses the network connection, but that is no fault of Thunderbird.
Next time you have an issue look at the online/offline icon in the lower left corner. It looks like 2 monitors and will have a red x on it if offline. You can change states by clicking this icon if your network connection is back when you do this.
Wild guess, the problem computer is a laptop and the problem free computers are desktops.
Thanks for your input, Airmail. In fact, the only computer showing this problem is a desktop all-in-one running Win8.1. We also have two tablets and a (stationary) laptop that don't lose the internet. And the failure in the Win8.1 computer only relates to the internet connection; the connection to the router is still strong. I was hoping there was some system-level reporting mechanism that allows applications to tell the system that the internet connection had failed. At least I could understand that failure mode. Is it important that our internet connection is via satellite? Bandwidth is about 10 Mbps but there are latency issues.
more likely the win 8 box is getting dodgy DNS setting. It may not even be asking the router for the information.
