said by ltm320:I am having some similar issues. I have RR .. had the SB51xx modem and purchased a SB6141, got it 4 days ago.
While my SB51xx was rock solid for years, the SB6141 is terrible and is rebooting itself every 1-3 hours or so. The signal levels all seem fine, according to Motorola's specs. -- Plus, hey. the old cable modem was perfect for years, although it was docsis 2, and the sb6141 is 3.
I did an online chat with RR's tech support .. the guy said "you have old firmware, go to Moto and install newer." I didn't think that was right, since Moto doesn't have firmware on their site and believed firmware needed to be pushed by the ISP. He didn't believe me. I verified this with Moto, naturally.
Question: Someone with a SB6141, can you tell me what your firmware is? Here's my info from »192.168.100.1/cmHelp.htm
Model Name: SB6141
Vendor Name: Motorola
Firmware Name: SB_KOMODO-1.0.6.3-SCM03-NOSH
Boot Version: PSPU-Boot(25CLK) 1.0.12.
Hardware Version: 7.0
Firmware Build Time: Aug 18 2011 10:27:53
The bigger question is .. if I get them to push a new firmware .. will that even help? It's really maddening how often it is rebooting .. I think it's the log entry "No Ranging Response received - T3 time-out" that puts it into a death spiral.
Same firmware, similar issue although mine is only with heavy upload. Second tech that came out found a noise issue on the main line down the road on Thursday. Linemen came out on Friday and did some work but the issue still persists.
I've gotten the same runaround with firmware as well. They swear they cannot push firmware to a customer owned modem.
