Odd, somewhat reoccurring bug

Sometimes I will load up a game, it will crash, send bug report, whatever and start repairing the client. Once it completes however, my account is still in a game and when I try to reconnect, it says my network connection is offline and to check it. I doubt it's actually offline as I'm literally typing this forum post, but I've had this problem rarely, but it does reoccur.

I also get these weird 1k-2k ping spikes out of nowhere since preseason started, and everyone I know as well, these spikes can last up to 20 minutes on rare occasions
