apple macbook air 7,2 very bad video streaming experience
I just received a newly ordered apple macbook air7,2 13". I have owned several mac products with me - iphone 6 plus, mac mini, mac pro & macbook pro 15" retina. The biggest different that I faced is the the video streaming experience with my newly arrived macbook air7,2. The video streaming is extremely slow and needs a lots of buffering. I immediately switch to my Mac mini & iphone 6 plus and stream the same video - these two devices stream smoothly in HD. Unfortunately, the MacBook Air did not perform as what the others.
Please advise on the troubleshooting steps.
Note: I did not see this as the ISP bandwidth issue because my others devices can stream perfectly.
MacBook Air, OS X Yosemite (10.10.2)
