Connectivity

Is anyone else have problems with League connecting to their internet, or just flat out disconnection even though your internet is fine? I just had a nunu game where I had to turn my router off and on to get in the game, had smooth playing and then got kicked 3 times because I supposedly didn't have a connection. I then do the same thing, turn off router and turn it back on. And then it happens again after a little while, but each time it happens my internet connection is fine and my ping doesn't seem to spike.
