Buffering problems on Kodi. Please help!

I have done everything and the problem is still there. I have noticed the buffering occurs with channels such as: Discovery Channel, National Geographic, Animal Planet, etc.. The rest seems to be fine...
 
Might just be the nature of the beast for now, they are still working on it, i noticed some buffering here and there, but never any buffering on commercials, also any android box is best run off ethernet not the wifi
 
Seems the U.S. Charlie channels are the ones having the issue. Then non U.S channels are perfect. Read somewhere else that Charlie is moving around a bunch of their channels to different sats, so that may be part of the problem
