Inside the Box

motorola sb6141 inside box

No matter how good a product is, there will be always some weakness. However the SB6141 modem is a great product that has evolved from its solid predecessors the Motorola SB6121 and SB6120, so there are few flaws. In fact these should not be termed “Cons” as it is not the weakness of the Motorola SB6141 but rather the accessibility provided by the ISP Comcast:

  • Comcast does automatically not support the SB6141 at the point of writing. In the other hand some customers have managed to get Comcast to manually provision their SB6121 for them. Once that has been done, reset signal will be sent to the modem and you have to repower it to get it working. Also to make sure that you buy the appropriate Comcast package to make full use of the Motorola SB6141′s capabilities i.e. you pay for the speed.

These are some of the Pros of the Motorola SB6141:

  • Easy to set up.
  • It is now supports AES traffic encryption for enhance security.
  • Has a build-in internal filter to reduce potential interference from MoCA signals’ inter-modulation beats.
  • Cheaper than its predecessors the Motorola SB6121 and Motorola SB6120.
  • Capable of channel bonding up to eight downstream channels and four upstream channels.
  • Shares the same firmware image as the hugely popular SB6121 and SB6120. This helps to reduce operator qualification time and eliminates configuration management problems for the ISPs
