Forums Connection Issues 10053 error, software caused connection abort

You didn't sound rude to me.

However, it's understandable that you place your blame on the closest possible piece of software, but it's very important to realize that there's a very very very little chance that it's a problem with mIRC.

NONE of the suggestions are guaranteed to work as mentioned in the post itself and this is a rather complicated problem to diagnose because so many factors are involved. None of these factors, however, are mIRC. I've successfully solved 10053 by replacing my router in the past (turns out it was dying), so I personally claim that replacing routers/NIC cards are the most likely solution. Most people don't like hearing that, though.
