Slow Streaming
I am fairly new at this also, there are probably others that have better suggestions.
youTube on my iPad takes about 5 seconds between tapping on the YouTube and the video playing, the time to buffer up and play the video seems to vary according to the resolution of the video. I also use Netflixs and I noticed that the movie will go fuzzy if I move the iPad to far from the wi/fi router.
I found from a posting in this forum that you can check your wi/if speed with speedtest app for iPhone, I used it to check my 3G and wi/fi speed. I have a D-link router (DIR 655) and my wi/fi speed runs 1800 to 2200 Kbps (20 feet from the router) it slows down to 1000 Kbps when my TV is streaming Netflixs from a LAN cable on my network. I read in another post that when a baby monitor was turned on, the person's wi/fi really bogged down. The app is free and I recommend you use it to check out your speed and it may help to trace a problem if you have one.
Best of luck
