| [Speed] Sacramento slow speed and modem change (SB4100)
For the most part, by the time Sacramento received the 6 Mbps speed upgrade, I saw consistent 5.5 Mbps downstream rates with my Motorola SB4100.
In the last two weeks or so, I've noticed downstream rates only up to 3 Mbps or sometimes less, although no decrease in latency (normal ping rates, no dropped packets).
I picked up a Motorola SB5120 and swapped it out today. My phone call to Comcast to provision the new modem was fairly quick and efficient, and now I am consistently seeing 6 Mbps downstream rates.
What does everything think about this? |

| I have seen quite a few people with the 4100 having download issues recently. Their logs show that the modems were registered back to DOCSIS 1.0, even though they still showed a DOCSIS 1.1 firmware.

What do I think?
I think it's crap! Comcast should either a: say they no longer support the sb4100 or fix the issue. Clearly the SB4100 is 1.1 docsis and a great modem able to do 8mb and more as I and many others will attest to, Comcast just messed something up. It's not a problem with the modem!
It's only been in the last 2 or 3 weeks that this started, seems it's clearly a problem with the firmware since it only started when my power went off. Someone else in the area with a sb4100 was still getting 6mb, they said no way it was the firmware and said my modem was bad, so I asked them to reboot their modem and they dropped right back to docsis 1.0 and now only getting 4mb & not happy, Hey I told them it would happen.  But it proves something changed in the last month on Comcast's side.
So personally I wouldn't just go out and spend $70 on new modem to replace a perfectly good modem that fully supports docsis 1.1 and supported by Comcast because they messed up the support on their end! I will just keep calling and complaining that they need to fix the issue. I wonder how much money they spend on tech visits around the country when I'm sure someone knows the real problem.
So I assume many users will have the same problems as soon as they reboot or lose power. People should call and tell them they have the 4100 and something happened in the last few weeks to many users across the country that fouled up support for their modem. |

| I agree that they should either support the SB4100 correctly, or not suppport it at all. Luckily, I was able to find a used SB5120 for $40, and since I've had the SB4100 for 4-5 years, I figured it wouldn't hurt to upgrade. I'd rather have my higher speeds, than wait for Comcast to fix the problem. |
