Hello! I've been using my Windows 7 Desktop with everything installed to its newest version. It runs smooth and opens applications much better then last time I used it. But I attempted to watch a YouTube video in 720p or 1080p HD, the video stops while the audio continues. I have updated all my necessary plugins for it, took the Google Video Quality Test, and many more. It said my PC was fast enough to watch high quality high-definition videos, but when I watch a video, it will work smooth in a cruddy resolution (480p or lower). My Internet hookup is wireless and can not be changed to a wired connection because of how my wire does not reach my router. My wireless Internet USB shows all bars visible and works with everything else! I would love an answer as soon as possible, thanks!

You can get a longer wire, or an extender.

Sorry, that shows the wireless connection, not its speed.

Have your ISP test your service.
