There can be different reasons for your internet slowing down. The time frame you mention (starting 3-5 days ago) is during the week between Christmas and New Years. There are times during the year when there's more activity than others and it's possible that you may have been experiencing some overload that will go back down as soon as the holidays are over.
As a test, however, you could go back to an earlier restore point from when it was working and see if that makes a difference.
If you've never done this before, Go to Start / All Programs / Accessories / System Tools / System Restore
check the box to Restore my computer to an earlier time and click on Next. You'll see a calendar with highlighted dates. Choose one of the dates just preceeding these problems and allow your system to return to that date. See if the problem goes away.
If this doesn't work, go back into System Restore as per the above instructions, only this time choose the option to reverse the change you just made.
Also, ATT modems disconnect when they are unplugged. I unplugged one to stop activity that was showing while my computer was turned off (twice) and in both cases, I had to call ATT the following day to have them reset it. There's something they do at their end.
Did any of the above information help?
