You appear to be offline bug

This bug is really starting to get on my nerves, I open up the league client and i get this error message so i can't log in something along the lines of "You appear to be offline so try restarting your client" And all my friends get this sometimes but for me, When it happens and i close league (I press the X button that's on the client and click accept to close league, And when i re-open the game the client thinks it needs to revert to the old update to start working again, So I have to install a 6 mb update again, It's not alot but the league client installs the updates at a snail's pace and bugs out alot so it's really annoying having to wait over 5 minutes just to open the damn game
