Champ Select Bug

During champ select, every once in a while, the countdown ticks to 0 and then nothing happens, my internet works perfectly find when that happens and I don't get the notification saying "you have disconnected from PvP.net". This has happened in multiple occasions (In ranked queue). Another example of this happening is when I am picking a champion, I click Lock in and nothing happens, then the timer goes down to 0, the chat box says everyone has left the room and I am stuck there without being able to leave champ select. (Still doesn't say I've disconnected from PvP.net). One way I found to solve the problem was to minimize the client window and then reopen it and it seems to connect in about 10 seconds later, but when this happens as I'm picking a champion I have no time to do anything about it. A reason I know it isn't a problem with my internet is because my brother will be in the same champ select as me (In the same house w/ same wifi - we both use wireless)
