Up for sale is a 3Com HomeConnect ADSL Modem Ethernet Model 3CP3647.  It is NIB and sealed, but the shrink wrap has a few dings in it and a 3 inch split.  Box is good though.  I have taped it so it won't split more.  Featuring U.S.Robotics technology.  Up to 150 times faster than 56K modems.  Always on Ethernet connection, no need to dial up.  Easy to set up for one or multiple users.
Supports full-rate and lite ADSL connections.
