Thanks for your input guys, I'll give that a try too....but....
In sort of a "close" to this thread, we had to have Comcast come out yesterday and look at the equipment. After 15 - 25 minutes, he finally left, leaving us with a new modem. It had gotten to the point that it appeared the modem was on, but you could call up IE, Mozilla, take your pick, and the homepage wouldn't even load up. It appears the modem has been my issue all along, because once I started up utorrent with the new modem, I had very high speeds once again (or as high as I've ever gotten)!
Thanks again!
