Are you on a wired or wireless connection.Wired connection
If you were on a wired connection the whole time, and now notice streaming speed problems, I suggest you clear your internet cache and delete temp files. The best way to do this is to use TFC which can be found here http://www.geekstogo...uide-t2852.html
Just scroll down and follow the instructions.
Then write back and see if this helps any.Wireless connections
It is to my understanding that If you are using a wireless router, speeds can change dramatically due to interference with walls, metallic objects, tvs and the like. If you were previously on a wired connection and then switched to a wireless connection, then this may be the cause of the slow streaming speeds.
other than that, this is the best advice I have to offer.
