Getting disconnected

Your opponent cannot disconnect you. It signifies a poor connection between chess.com and your computer. Are you using a wireless or slow connection? There's really not much that can be done about this, but it's not your opponent's fault.
Other remedies are listed in this chess.com helpfile. It's a helpful read.

I know how one can disconnect anyone who plays with them on Chess.com.
The secret is DISCONNECT themselves from the other player; hahaha!
It is not the connection to Chess.com that disconnects. It is the connection to the game instance. I have "disconnected" while ping < 40 ms and "online chess" shows connected.

Ya, there have been too many times where I am disconnected when my opponent is down to 1 or 2 seconds and I am up material. I think there is a bug for sure.

I have an excellent Internet connection, but yesterday just after my opponent dropped a piece I was immediately disconnected for the first time ever and lost. I'm sure that chess.com could either validate or disprove our 'conspiracy theories' by simply studying a statistically significant random sample of positions that were disconnected and see if engine analysis indicates an abundance of resignable positions or games where a player was in time trouble.

I agree with Yargo; I had one instance where the message said disconnected, but during this time, (about 30 secs), my opponents clock kept winding down.

i had it happen too
when i was winning 2 sec left
with a 2000 player
chess.com needs to look into this

Yes, most of my losing game, it has done by time only. (disconnected/severe lags). I've experienced a sudden interrupted connection problems and I have lost the 1 minute-bullet game 18 times in a row due to this problem.
It more than words can say !

It is very difficult to excellently test software to run on many platforms. Perhaps a good beta test program (unrated?) that gave trophies for bugs found could help new versions without annoying the unwary. The hardest part is getting stack traces from random machines. It would be hampered by the timing changes of the trace routine though. But I believe many members of this community would like to help software quality control and be willing to take chances of problems as long as they are an accepted risk.
I play quite a few games in which my opponent is disconnected multiple times...each time they have...YEP you got it, 3 minutes to reconnect. I understand the intent of being fair to folks who have a weak connection. HOWEVER, it is very annoying to protract the game time after time for the return of my opponent. Sometimes it seems they want me to give up and abandon, to get them out of a jam! I think after "two abandons" ...no mas'
