Hello! I'm a bronze player in NA who has a MMR of about 800 (https://na.whatismymmr.com/) and I feed pretty much each game (pretty much impossible to carry me)! So my problem is that sometimes my internet and laptop start acting up, causing a low FPS and ping spikes that skyrocket up to 4000 every minute. Unfortunately this results in me dragging the team down and thus the team hating me. Trust me, it's not fun playing under these circumstances and I would like to avoid them.

I'm sure this topic has been requested one or more times and there might be some technical issues regarding it, but please at least warn the player if their internet might not be good enough (especially for ranked) to play so can they wait off the lag.

P.S. In the comment section please do not joke about this and tell me to get a new laptop and internet since it's only in league that I face these lag issues. And also, I have no intentions of quitting this game because I have spent a year and $5 on this game already. Also, troubleshooting tips are appreciated!
