I think there was some kind of mixup with people who rented vs own from comcast but I just previously said … what I saved in rental fees the 6141 has already paid for itself and im still ahead getting the 6183 for less than retail… so its win-win … and the 83 has more download channels available to it so there is less potential for congestion since the modem has more channels it can select from … (not that its any faster but it has more options now)
