Except for the size and color of the case, they both appear to be very similar. Since I have both, it would be good to know the differences between the two.
The C90 was provided for my Bell South Extreme 6.0 ADSL service and the B90 was used in a slower less expensive ADSL service my Dad used but both appear to have the same capability.

The 6100 is a newer version of the older 2200.
If they both work, then keep one as a spare backup in case the other fails. -- AT&T Uverse; Zyxel NBG334W router (behind the 2wire gateway); openSuSE 11.4; firefox 4.0
