Champion Randomly Becomes Unresponsive [GAMEPLAY]

I found an old post on this a while back, but I can't seem to post in it. Either way, what's happening is the game won't lag, I can see all other players moving and casting abilities, but my champion will lag out. If I clicked the champion to move to a position, he/she will stay on that course and there's nothing I can do to prevent it until the unresponsive spike ceases.

Abilities do not work either -- my own I mean. However, at the end of the unresponsive spike, usually one of the abilities I was trying to use, gets cast. It's incredibly frustrating.

This can happen at any point in the game, but it's most noticeable in early game when I'll just stop in the middle of the lane, unable to move, and wait for an Ahri E to smash me in the face.

This seems to happen anywhere from every 2 minutes to every 5, but it's been on going for a full day now.

It's happened on all champions I've tried since I noticed it. But they are as follows

Teemo Zed Yasuo Ahri Rengar Riven Nautilus

Any information on this or a fix would be greatly appreciated. Thank you.
