hello,
recently I was experiencing GREAT download speeds up to 3Mbps, I don't know what happened but in the past few days my down speeds have shrunk to less than 1mbps, more like 700KB. Can you please advise as to what has happened or what I can do to make this better? Any information that you can provide would be greatly appreciated.

Thank you in advance for your time.
