you will eventually have to upgrade because they wont allow the older modems on upgraded networks.
getting a 6121 (for 55$ new) isnt too much and the ROI is pretty fast.
a 6141 is still around 90$ but thats even more futureproof.
Personally I went with the 6121 for 65$ with free gigabit switch combo deal.. because I didnt feel I'd upgrade anywhere close to what that the modem would support easily.
The problems associated with having an ancient modem on a newish network can be legion.
