I'd say 25% of the time I tap a YouTube video to load it will not. I'll get an error to tap again to retry. eventually it will work. very unstable. but after visiting friends apartments or other places with wifi, YouTube always loads perfect. so clearly it must be my router which by the way is brand new. and I have a very fast connection. any idea what is happening here? works 100% fine on my laptop. it's just my iPhone and iPad.
