Are you on a wired or wireless connection.
Wired connectionIf 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

Then write back and see if this helps any.
Wireless connectionsIt 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.
