I just bought the Galaxy 10.1 tab last week and absolutely loved it until I tried using youtube. Most youtube videos start for 2 seconds and then start buffering for a very long time, only to start for a couple of seconds and then start buffering again. My wifi icon in the bottom right of the tab is usually gray instead of blue and I am not sure what that means. I am connected to wifi and can use the internet but it is youtube and other video that does not play properly. Could this be an issue with the router? Are there particular settings my router should have to avoid this problem? Thanks for any help. I really don't wan't to return the tablet!
