Probably is weak WIFI signal indeed. I get that time to time too. You can tell you have no connection to site if you can't do anything within the chat lobby or try clicking on the options button in lower left if that does nothing you know you have no signal. When this happens, you need to figure how to strengthen it by either connecting to router with Ethernet cable or move closer to router. In some extreme cases, you may need to get an stronger router or an extender because you have too many computers, cell phone or computer pads connected and its slowing down your internet. Typically when I get weak signal, I just move to another room and then I see that my opponent has moved and regained connection.
Anytime you feel its odd that your opponent is taking too long for a move, test to see if you have connection because the program will make it appear with his buffer counting down he is not doing anything when its really you.
You're going to be able to get me on this one, too, Lo.
But this is an excellent post by Midnightguy. It's likely the problem with both the originator of this thread, dmt kingpin (who no longer appears active), and the very recent nopuno, who reopened the thread.
