Turbo-connection, but won't download
 

I don't quite understand whats up. About six days ago, my connection slowed down, eventually it gets up to the turbo-charged level, but then nothing will still come through even if I have like 50 available sources. I also frequently am told that I lose connection, even though I haven't, and everything ends up saying there are no sorces, even though the search shows a bunch. Its not behind a firewall so i'm not really sure whats up. Thanks in advance for any help anyone can give me
