Bump. Must have happened to me 30 times today in the last two hours. Got reported and called a stupid noob two different games because my team mates are like "there goes that dumb Trundle or Udyr who won't stop charging the enemy that leapt out of the bush and is chasing him towards another enemy."
Funny is I'm on a VPN for work sometimes and my connection is solid. So is Skype and I can browse the net. I tried the IPV6 thing, I'm about to go back in game and see if its still happening.
EDIT:
Nope. Didn't change a thing. Still "Attempting To Reconnect" every game. 
Sorry Clubbems, Trundle don't know what going on
EDIT 2:
Some patch downloaded, rebooted PC, reset winsock and tcp/ip, disabled IPV6.
And I get called a noob again cause "Attempting To Reconnect". Trundle just walked past a turret to the enemy nexus for some reason. Oh, they just scored an ace. Thanks a lot noob. Reported.
I'm gonna go play WoW since it appears this issue isn't resolved.
