ar0nic, Comcast is going to surge in the beginning that what the boost is suppose to do. If your getting that good of speed with that file I wouldn't change it! As far as your other problems I won't be of much help. I don't use a router and I still have basic Analog Cable TV. Sometimes it does get a little slow in the peak hours for testing. you might of hit it at a bad time or Comcast routed you through a bad relay server. Someone will probably come along and help with your other issues. Have a great day.
