Everytime I watch video on the internet whether its on youtube, a news segment from yahoo, or on hulu and even on my ipod touch (using youtube with home internet connection) videos will play fine for a while then stop and not work for a minute and then be working and then stop again or just not work at all. Video and audio appear and usually work intially but then stop working, but the screen doesnt black out. This is just recent. i think it may have something to do with my wireless internet because its on my touch too. How do I fix this?

ive tried letting it load and coming back
