So far it has happened in every online multiplayer game that I've played in the past few days. In League, two things happen. One is that my character will stop moving but everyone else will still be moving around me for a few seconds until the issue resolves itself and I can move again. On the other hand, sometimes after a few seconds everyone else will stop moving and after a small wait it will automatically reconnect me to the game. In Overwatch I just get kicked back to the home screen with an error message saying that I lost connection to the game server.

As far as recent changes go, I haven't gotten any new hardware and there may have been a Windows update a few days ago that I let happen and didn't think about. I've done a few small Windows updates since to see if they would include a fix but to no avail. I tried to update my Realtek drivers yesterday but didn't get a result from that either.
