We have a cricket broadband thing that plugs into the usb port and provides internet. For a couple weeks, it will be awesome. It will load pages in just a few seconds, play youtube videos, the whole bit. However, every once in a while, for like a week it will be slow as all get out. Pages take at least one minute to load, youtube videos buffer literally every second of the video. At first, I thought it was the weather or bad signal, but it does it even when the skies are clear and my cell phone is getting great reception. Anyone have any thoughts on what might be the matter?
