I've been experiencing the 10053 error for quite some time and I've googled till I'm blue in the face. I'm primarily using my HP laptop with Windows 7. It seems I would get this error after having been idle and as soon as I would use my wireless mouse and clicked the screen, my mirc would disconnect, almost every time. Sometimes my JMeeting would be unaffected while at other times it too would disconnect. I ran across a suggestion to uncheck the box "allow the computer to turn off this device to save power" in my Wi-Fi router's Power Management. I gave it a try and so far I haven't gotten the error again. Time will tell if this was my fix.
