The most recent software version available for the AT&T (SBC) Speedstream 5100b and 4100 modems is 1.0.0.53. As it has been several years since the last software update was issued and Siemens has apparently exited this aspect of the modem business by forming a JV with Nokia, it seems unlikely that any more updates will be forthcoming.

Although the firmware and installation instructions for the 4100, are no longer available on the Siemens website, the Wayback Machine DOES have a copy of the information. It may take a while, but you'll eventually be able to download the firmware for the 4100 at:
»web.archive.org/web/200612292024···4100.zip

And the 5100b at:
»web.archive.org/web/200612292024···100b.zip

To see the instructions for the 4100, click:

For the instruction for the 5100b, click:
»web.archive.org/web/200701070711···0b.shtml

This version contains fixes for AOL for Broadband 9.0, DSL power-off enhancements, a fix for restoring the memory in the modem, multiple fixes to the statistics web page, enhancements to DHCP, and a security fix.

  • Will the 5100B firmware work on a 5100 plain?

  • I think the 5100b firmware link is wrong. It should be (after some googling to find the letters): http://web.archive.org/web/20100906042502/http://subscriber.communications.siemens.com/upg/005-E142-A2B-SBC53-5100B.zip
