I get a DC 6-9min into game then its fine

Every game that i go into at about the 6 minutes mark to 9 minute mark i will disconnect for about 7 seconds randomly then reconnect and i will not get a ping spike or anything. What would the cause be? I have a wired connection and i have run pings and i dont get any drops in cmd while playing league but i will stil dc just that once in game. Its a bit frustrating in ranked games. Can anyone help?
