[Crash in Gameplay ]Champion freezes but game continues as normal.

This is happening a lot lately. I started noticed it a couple of patches ago.

During the game at random times, my champion just freezes. I can still see mouse clicks, can still type, and can see everything that is happening but I can't do anything at all. The game continues normally, unlagged adn in realtime as I'm just standing there unable to do anything. This happens for about 5-10 seconds, then the Attempting to Reconnect comes up. Nothing happens therefore I'm forced to shut down the game otherwise it's a free kill for the enemy team. Usually when I attempt to reconnect, it's a black screen and after 15 seconds, I get the notice that a firewall is disrupting the connection(obviousl ynot the case.)

This doesn't happen every game but it happens in about 40% of my games. I can't figure out a pattern on why it happens, it just seems to happen at the most inconvenient times.

I've seen other people talk about this issue but I haven't found a thread where there was a fix of some sort.
