Starting in June my boys started playing multiplayer minecraft on their tablets (one is a kindle fire hd7, and the other is a samsung galaxy 3 tablet). About a week ago, they can no longer connect together, with the exception of a few times. Usually it involved waiting for a few minutes until the game would show up on the other device. But it doesn't seem to work any longer.

I tried connecting minecraft pocket edition with my kindle fire hd7 to my sons kindle fire hd 7 and they connected fairly quickly. I just can't figure out how to get the samsung galaxy tab 3 to connect now.

The local server multiplayer is already on. Also, I reset our wireless router. Doing that helps with the kindles connecting, but has done nothing yet for the samsung galaxy 3 tablet.

Thanks for your help,
