It's curious that your screenshot does not show time stamps next to the chat dialogue but, it does next to my supposed disconnect. In fact, your screenshot showes a completely different format with no timestamps in the chat sequence and a different font face in the last two messages which as you can see never even hit my screen. You can seen in the image that I was still connected to the internet and working in a different window at the time so, the likleyhood that I disconnected accidentally is preposterous.

I do understand your desire to pass the buck and paint me as incompetent. After all, my feedback must have been hard to swallow. You might find that refocusing on the problem and finding a solution that prevents other client's from have the same experience I did to be a more construtive use of your energy. 

I resolved the issue on my own... no thanks to tp-link chat support.
