Recurring Network Waning

So, I was experiencing some lag issues and decided to repair my game and when I came back and tried to play a game and it lets me get into the 90%-99% and then it says "Network Warning: You have been disconnected. Check your internet and try again." I tried 2 different connections that worked for other things(Skype, Chrome) and it worked for League before and I tried restarting my client multiple times to no avail. Anyone else having this problem?
