Hello everyone!
I run a small-time cable plant with about 300 customers on an apartment complex. Over the years we have slowly upgraded our headend gear, starting with a uBR7111, then a 7114, then a 7246VXR. We're moving to a 10012 next year if all goes well.
We are starting to run into trouble with some modems running outdated firmware, mostly Surfboard 5100 series units. All our modems running new firmware are fine, but some of our oldest SB5100 units are running ancient firmware and aren't handling things like load balancing and ATDMA properly. Five of them can't even connect to ATDMA upstreams, period. We have to maintain at least one old TDMA channel just for them even though the model should be compatible.
Anyway, as near as I can tell, modem firmware upgrades are the ISP's responsibility, not the customers. So..... Where exactly do I get modem firmware files for our plant?
Thanks in advance!
Motorola is now part of Arris so the official source of the firmware is:

I am not sure if this requires a service agreement with Arris (we have one and I have never tried without)
as 5100s are quite old if you ask on this forum you can probably get someone to send them to you.
The latest version for a plain 5100 is Version 2.3.9.0-GA-00
Where to send?
Quite a few of the early SB5100s were shipped with "DOCSIS 2.0" disabled, specifically the ADTMA upstream capability. Check the SNMP set 1.3.6.1.4.1161.1.19.3.1.25 (cmDocsis20Capable) on the affected modems, it is probably set as 'disable'.
