Players are not ready, trying to reconnect after every login and game

Running into loads of problems. Sometimes it's stuck in authenticating status and can't even login properly. If that gets through, trying to reconnect comes up. And then, players are not ready with grey button blocks my queue. Even if I get to play one game (usually without any lags within the game), the client either becomes completely dark after honoring a teammate or trying to reconnect comes up again. Rinse and repeat. I've got some free time so I wanted to just binge and play league for hours, but all these problems are just too annoying and I don't know how to solve these issues. Firewall, dns, administration etc etc. followed through the troubleshooting connection issues guide, reinstalled many times, initiated full repair, restarted Mac, but these problems just won't go away.
