TV box problem.

Hi. Recently bought an ott mxq tv box with a lot of stuff already installed including kodi and showbox etc.
Nothing will work. I don't think it's a wifi problem because same problem with ethernet not genesis or salts or what ever plug in I load on kodi will work. Most of the time it won't even let me click into a tab like 'genre' or whatever on any plug in. I also have an older android box and recently the same problem on that too. Also showbox has problems not loading. I've been trying to fix for two nights now and am close to finding my hammer to be rid of it. Someone please help.
