Re: [TWC] RR Standard with Motorola SB6141 Speed Increase?

said by ericn32:

Also, you might not need the SB6141. It bonds up to 8 channels, giving you about 300 Mbps throughput. The SB6121 bonds 4, giving you about 150 throughput. If you don't think you'll ever want more than 150 Mbps during the life of the router, you just need the SB6121, which retails for $80 on Amazon.

Sorry, the SB6121 is NOT approved by TWC. People have reported here that they were able to talk TWC into provisioning it for the Standard tier, but TWC will NOT provision it for use with the Extreme (30) or Ultimate (50) tiers. Either save your money and get a cheap D2 modem, or spend the extra $20 and get the approved SB6141.

Which is odd to me since both the 6121 and the 6141 use the same software versions, one would expect they would both run the same on the network. This is eventually what has allowed comcast users to start owning the 6141, since that model was never on their allowed list.

Are you sure about that? My (limited) research shows the 6121 uses a Broadcom chip whereas the 6120 and 6141 use a TI chip.

As far as TWC not approving the 6120 and 6121, I'm assuming it's an administrative prohibition. Even though it does bonding, it only bonds 4 channels. With 38 Mbps channels, someone on the Ultimate (50) tier will be using almost 50% of all 4 channels by themselves. That's not gonna play nice with D2 equipment also trying to use those channels!

From the 2nd page:
"Benefits:
Easily add the SB6141
to a deployed family of
SB6120s and SB6121s,
all three models utilize
the same firmware
image. This reduces
qualification time
for an Operator and
eliminates configuration
management headaches."
