Another thing you can try is clearing some memory and RAM while quitting the game. You can manually remove in Settings > Application Manager but you can also use third-party apps from Play Store/App Store to help clearing managed well.

Because it is a connection issue, there will always possibility that your own connection is having something - check if other apps are running and using your data as it slows down your speed. Use speed test apps/websites to check the speed and see if it's slower than usual.
