Hi, I am new to I pad and also just purchased a new Mac book Air. I am having trouble with videos from u tube and Vimeo pausing/stopping in the middle. Just bought a new router which is 802.11 dual band with a separate modem, just not sure what to do about it. I'm a little frustrated. Quite an investment with little results. My Kindle Fire does a better job. Any ideas on what could help ??? Any info would be appreciated. Thanks so much
