What you should do is get out of the room. Go outside if its nice out, hang out with friends, etc...Give it some serious time to update. If it has not progressed like 1-2 hours later, then your internet connection is probably horrible, or you have a defective unit.
What I have is verizon online DSL with a LinkSys router and idk my modem..Its not incredibly fast, but I can't complain about the speed, I mean, my update took like 15 minutes. (using the WiFi MaX connector)
