All yesterday I had the RADs error, until I used googles public DNS.
Now today I get nothing but unable to connect to pvp.net server. I have charter internet, I have spent around 5 hours today alone trying to get it fixed(It was occuring on european servers as well, except i was able to get all the way to character select a couple times). I have done every single recommendation on this forum, reinstalled 4 times, contacted charter internet 3 times on the phone, and twice on chat. They all say "its a problem with the game, contact riot" no matter how much I tell them I dont think thats the case. I have officially spent more time in the last 2 days trying to get the game to work, than I have played in the last week.
