"Attempting to Reconnect" Issue with Perfect ping/connection?! + Reauthentication Error?

I've logged in to that weird "reauthentication" error once but the whole thing started with me getting an "attempting to reconnect" notification in mid game when nothing had been wrong all day. I mean, I was legit hardwired into my laptop so there was NOOO way it could have been my connection. I can still load youtube and everything else. I'm not sure what just randomly decided to go wrong but nothings working to fix it.

a) changing to 5ghz= not possible for my laptop b) Making sure its not your wifi/etc( I get 125mbps plugged in and anywhere from 35-75 straight wi-fi, its sufficient) c)making sure your date and time is correct= date and time are both exactly on the money d) restarting computer/ restarting league/changing your password/etc

Its just weirding me out because I haven't ever had a problem just start mid game like that. Help please? Any possible solutions?
