I've owned an SB6141 for about 3 years now with few issues (desktop wired to Netgear R7000). I recently upgraded from Performance Pro 150/5 to Blast! Pro 250/10. After reading these boards I have of course verified that an 8x4 modem like mine is usually hard pressed to reach the maximum download speed of my plan. I've also read that sometimes Comcast takes a while to reconfigure the modem for a new plan. The modem logs have a very small window where you can discover if you've received the new config and I noticed that the Help tab contains modem-specific details but not date of last config update. Right now, I'm achieving about 120/5 which is about the same as my previous plan (tested with testmy.net and speedtest.net to SF). I don't mind if I can only get ~200 down before I get a new modem but I really was hoping to get that doubling of upload speed because I do a lot of backups. My two questions are: how do I check that my modem has been properly reconfigured and also, how can I know that it has the right firmware for the job? Any help is much appreciated. Modem info:
Model Name: SB6141
Vendor Name: Motorola
Firmware Name: SB_KOMODO-22.214.171.124-SCM00-NOSH
Boot Version: PSPU-Boot(25CLK) 126.96.36.199m3
Hardware Version: 7.0
Serial Number: ****
Firmware Build Time: Feb 16 2016 11:28:04
Solved! Go to Solution.
It's the boot/config file you need, not the firmware. Try powercycling the modem. You could call in ask them to check your account and get them to push the correct boot/config file for Blast Pro 250.
Could be that the device is not on the approved list for Blast Pro 250 so they may not have a boot file for it. I have seen a couple of reports of people getting upgraded with that modem, but as you know, you may not get the full overprovisioned speed with it.
Good Luck !
I don't think they can provision your modem for a speed tier beyond its capabilities. So either upgrade the modem or save yourself some $ and go back to your old speed tier.
As has been stated, the 6141 is not approved for the 250 speed tier;
It will default to using a Performance Pro 100/5 boot file instead.
OK, thanks all! I managed to snag a new CM500 on Amazon for $47. It seems that 32x8 DOCSIS 3.1 modems are overpriced for a standard that was released in Oct '13 with products coming to market in Q4 2016. I guess it's because the majority of Internet users don't have high level plans yet so there is lower demand.
Last question about the firmware though: there's really been nothing to improve for the modem since early 2016, or is it just that Comcast doesn't bother, or both?
