Client and Gameplay Issue

So I just wrote this all out, and accidentally hit backspace and it all deleted so I'm really pissed. Anyways, League has been really fucking annoying lately. This has been going on for at least 4 days. To simplify everything I had said before, I'm just going to describe the in-game effects. I keep getting this really weird lag, and the first time it happened, I mentioned it to my teammates. One of them told me it was "packet loss." He told me that it was more of a server issue, and that there wasn't really anything I could do to fix it, but it's super annoying that it's still happening. Basically, I lag out every single game. The lag varies a lot in its intensity. The weakest it ever is, is everything except champions will freeze, and the champs will kind of teleport to wherever it is that they're going. In other words, if a champs is heading towards dragon, I can still see them heading towards dragon, it's just not fluid, and the champ will kind of teleport sporadically in its path. The worst it ever is is where it lags me out completely. Sometimes it tells me I'm reconnecting, other times everything just freezes except for minion animations, but health bars don't decrease, nothing moves, I'm not alerted if I'm taking damage, etc. In the rare instances where it actually disconnects me, it'll say my ping is 500, but other than that, my ping NEVER increases in these lag instances. My frame rate also never decreases. Most of the time, though, it doesn't disconnect me, however, it's like I disconnect because my champ starts to go back to base. This happens every game, at least 3 times a game, and it happens without warning. Please help me find a way to fix this, because honestly the game is not enjoyable whatsoever anymore. If my teammate was right and there isn't something I can do, please let me know. At least then I can know I just have to wait it out or something.
