Primarily in your ISP's support Forum here at BBR and which one you should choose from in the list below depends on your region of the US. The 5100 (and the new 4100) that AT&T/SBC uses is Crippled and running Customized Firmware per AT&T/SBC's specifications using a Branded Web Interface. It is completely different from a Retail 5100/4100 Router, PPPoE Modem or Bridge series. We'll still try to help you out on basics, but you'd be better served by choosing one of the AT&T/SBC Forums below especially if you are having any kind of connection or setup issues. Thanks for your understanding.
The following links below are taken from the various AT&T/SBC FAQ entries to help you find what you need quickly and to prevent over-duplication of information in multiple FAQ locations at BBR.

3. Click the "Advanced" button in on the left hand side to toggle expanding the grey button list providing more options.
4. Click the grey "Update Modem " button.
5. If you are prompted to "Enter the Modem Access Code," then enter the Modem Access Code that is located on the yellow sticker on the bottom of the modem, then click the "Continue" button.
6. Click the "Browse…" button and then select the location of the "004-E142-A13.upg" update file on your Desktop (or folder on your hard drive where you chose to keep it).
7. Then click "Open" to accept that selection and it should return to the GUI.
8. Click the blue "Update Software from PC" button at the bottom of the GUI.
9. Once the file has been uploaded to the modem, you will see a screen saying "The software update completed successfully!" and "The modem will now reboot to let the new software take effect."
10. After the modem has restarted, you will see the normal startup Login GUI screen with a red warning message saying that "the log on restart is not recommended."
11. Click the red underlined text where it says "Click here to clear the log on restart." This will turn off Persistent Logging. The Persistent Logging feature should only be activated by a technician during trouble-shooting procedure.
12. If you are prompted again to enter the Modem Access Code, enter the Modem Access Code that is located on the yellow sticker on the bottom of the modem, then click the "Continue" button. (Once the code has been entered, keeping the log on restart will be disabled and the warning message will go away.)
13. When the Log Page reappears excluding the (Click here to Clear the Log on Restart) message, you can now close GUI Browser.
14. Now, the firmware has been upgraded, and the modem is ready to use.
