We had the same problems, our gaming salesperson suggested that we uninstall the game (but don't delete saved game data) and re-install the game. Seems to have done the trick. Still getting the occasional Baboon, but much better than it was. Plus, by not deleting saved game play we still have our stats. I don't think these errors have anything to do with any of our internet, something's wonky with the game itself or their servers.
