3.1 Speedstream 5100
1. In your web browser browse to »192.168.0.1 This address will be located on a yellow sticker on the bottom of your modem. 2. The first screen will ask you for your Modem Access Code. This also will be located on the same yellow sticker. 3. At the login screen type in your SBC/AT&T member ID and password. 4. Click Connect. 5. If everything is successful you will get a screen that says, "You Are Connected." and your Internet light will go solid green. If you username or password is invalid you will get a screen stating such. If there are other problems you will get a screen stating, "The DSL connection is down."

by Maxo The modem itself, with the shipped firmware, supports 3 modes; PPPoE on board, Bridge mode, Bridge mode with IP Address pass Issuance. To put the modem in Bridge modem do the following: 1. In your web browser browse to »192.168.0.1 This address will be located on a yellow sticker on the bottom of your modem. 2. The first screen will ask you for your Modem Access Code. This also will be located on the same yellow sticker. 3. Select Advanced from the blue buttons on the left. 4. Click the PPP locations button. 5. The modem may ask your for the Modem Access Code again. If so type it in again and click continue. 6. Select the radio button labeled, "Bridged Mode (PPPoE is not used)" 7. Click Save Changes. 8. A "PPP Location Warning" page will come up. Click "Change PPP Location." 9. A "Restart Needed" page will come up. Click "Restart" 10. Reboot your computer and router (if applicable.) You will now need some form of PPPoE software on your computer or a router that supports PPPoE. Be warned that even if you are using Enternet 300 or XP/OSX's built in PPPoE SBC tech support will not troubleshoot connectivity issues until you have put your modem back in PPPoE on board mode.

by Maxo A correction for the FAQs in regards to the 5100b. This could be a new item (e.g., Q: When does the 5100b asked for a modem access code?) as well as corrections for the steps in the other exiting questions. The modem access code is not asked for more than once in a session. It is not asked for on the first acecss to the modem. It is asked for when you try to access a page whose primary end result would change the state of the modem or when you click on a button that would change the state of the modem on a page that is primarily an informational page. And then it is only asked once per session. In addition you might clarify why to use Bridged mode vs. Bridge mode with IP Address pass Issuance. The latter is preferred so that you can easily return to the GUI without resetting the modem back to factory defaults or going through manual pc based subnet configurations. However Bridged modem with IP address issuance may cause a conflict for users with plain IP over 2684 (aka DHCP) service and with may not always work with some Ethernet to Ethernet routers (the routers configuration can ususally be changed but what happens by default varies from router to router manufacturer). by The Chef The easy answer to this and for some time has always been: "At this time, NO. Maybe with future software upgrades." Now, the answer for advanced users is yes, but the procedure is involved. First you must gain access to the modem CLI: »SBC DSL FAQ »How can I access the Speedsteam modem's CLI? . Then you must use the correct cfg command listed here: »SBC DSL FAQ »How can I use the cfg command on the Speedstream modem? . The new IP that you set the modem to will be retained through power cycles and restarts, but will not survive a reset to factory defaults. by MrFixitCT Current Software Version: 1.0.0.53 Available at »web.archive.org/web/2006 ··· 100B.zip Please note: this is using the Internet Wayback machine. The original link, hosted by Siemens, is long gone. This link may be slow, and you might need to retry to get the file to work. It was valid as of August 2010. Feedback received on this FAQ entry:
by MrFixitCT Routers with the default IP of 192.168.0.1 (example Netgear) conflict with the 5100B default of 192.168.0.1. The administrative access IP for the router has to be changed, since the 5100B's cannot be changed. by MrFixitCT If you want to network your connection with the 5100b you will need a router. The 5100b hands out only one LAN IP address (and does NAT) so a hub will not work. There are two methods you can use to network the 5100b. While initially, the first was the recommended version, as time went on, and users and support got used to the idea of PPPoE on the modem, the second approach has become the preferred method because it allows access of the modem's GUI for DSL statistics and diagnostics through the router. Method 1 (Single NAT) - 1: With your computer plugged directly into the modem bridge the modem using the FAQ entitled How can I put the 5100b in bridge mode? 2: Plug the router in between the modem and your computer. 3: Set your router up for PPPoE and put in your full e-mail address and password. If it asks for an IP address or anything like that you can just leave those fields blank. 4: You should now be online, given the possible need to restart your devices. Method 2 (Double NAT) - 1: With your computer plugged directly into the modem follow the FAQ entitled »SBC DSL FAQ »How do I setup the 5100b to connect to the internet? 2: Plug the router in between the modem and your computer. 3: If your router has an IP address of 192.168.0.1 then you should change it to something else like 192.168.2.1. 192.168.1.1 will work, but if it assigns 192.168.1.64 to a device, it won't route correctly, since the 5100b (or 4100 or 4100b) will assign the router 192.168.1.64 on its WAN side when the "Use Private Address Option" is selected. 4: Setup your router for DHCP on the WAN side, or set it statically to 192.168.1.64 with a subnet mask of 255.255.0.0. The latter choice is preferable and avoids the 10 minute-long, internet access "lock outs" that occur when some routers mishandle their WAN-side DHCP release and renew. 5: You should now be online, given the possible need to restart your devices. Note: Although this Method 2 is termed "Double NAT", the modem functions in a DMZ mode and passes all port traffic through to the router. There can be a connection drop or lock up problem with this method, if too many TCP connections (sessions) are opened by some gaming or P2P software. Apparently the modem's NAT table memory overflows when this happens. Feedback received on this FAQ entry:
by Maxo 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/2006 ··· 4100.zip And the 5100b at: »web.archive.org/web/2006 ··· 100b.zip To see the instructions for the 4100, click: »web.archive.org/web/2007 ··· 00.shtml For the instruction for the 5100b, click: »web.archive.org/web/2007 ··· 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.

by Maxo Many different modem models show an estimated maximum attainable sync speed on the GUI pages, but the Speedstream modems do not include this capability. The Speedstream 5100b/4100/4100b modem analysis tool (aka DMT tool) programmed by deblin can estimate the upload/download maximum attainable sync speeds for a line if provided with a link to a saved copy of the Technician Readout page on the user's hard drive. The 5100b/4100 modem must be using software version 1.0.0.53 to provide the complete results for the upload side. The 4100b modem uses the factory 1.0.0.63 software. This DMT tool also works for the Motorola 2210-02-1002 modem (firmware 7.7.3r5) as well as the Speedstream 5100b, 4100, and 4100b modems. If the DMT tool link is broken, please use the original DMT tool beta test site instead and the instructions in this FAQ. First you must be able to access the modem's GUI either by connecting directly to the modem or by letting the modem do the PPP and issuing a public/private IP to wan/internet port of router: »AT&T Midwest/Ameritech FAQ »Funhouse 5100b Setup and Reference Info or by one of the other advanced methods: »SBC DSL FAQ »How do I access the modem GUI thru a router - advanced methods?. To save a copy of the Technician Readout page, »192.168.0.1/techreadout.htm, on a Speedstream modem with a non-IE browser, simply use the Save as command. If you are using any version of Internet Explorer, then after using the Save as command, you must change from the default setting on the Save as type: drop down box to the Web Page, HTML only (*.htm,*.html) choice and then save the Technician Readout Page. On IE, alternatively you can use the View -> Source menu item on the Technician Readout page. This will open up the HTML source in notepad (or whatever your default text file viewer is). Save this file as "techreadout.htm" (the file name doesn't matter). For a Motorola 2210 modem, save the Technician Readout page from »192.168.1.254/techreadout.htm by the one of the above methods instead. These estimates will under report the actual maximum attainable sync speeds if the modem is not running at full output power. Because these modems do not report the output power levels, there is no way to compensate for this possibility. Also note at the slower speed plans such as 3008/512 and below, the modem only lists the statistics for tone bins (frequencies) it is using. So the speed estimates made from limited tone bin data tend to be slower than the real potential of the line. The chart below (click for full image) was produced by the modem analysis tool for a good 768/384 connection on a relatively short loop. It is an extreme illustration of the limits of these maximum attainable speed calculations. Although this line is known to be running at the maximum allowed power levels, no data is reported by these modems for the unused, higher tone bins, and without that data, the DMT tool can make no estimate of the speed capacities of those tone bins. AT&T techs estimate this line's maximum attainable sync speed at 6976 kbps instead of the tool's estimate of 4596.  If you are asked to post the tool's results in a thread and you don't have the ability to make a graphic capture such as the above shot, then you can post a copy of the DMT chart link address (with Firefox you right click on the chart and 'Copy Image Location' and with IE you right click on the chart, select Properties, and then copy the entire Address:(URL)) and a simple cut-and paste of the text such as done below. This will make viewing your results much easier for those reading your thread: »/users ··· aph=true Downstream Current Rate (Reported): 768 Downstream Maxrate (Estimated): 4596 Downstream Bit Margin (Calculated): 252 Upstream Current Rate (Reported): 384 Upstream Maxrate (Estimated): 1058 Upstream Bit Margin (Reported): 92 Bit tones with notches/missing bits: bit(s) 38:43 163.875 - 189.75 KHz bit(s) 110 474.375 - 478.6875 KHz bit(s) 123 530.4375 - 534.75 KHz bit(s) 137 590.8125 - 595.125 KHz bit(s) 143:255 616.6875 - 1104 KHz The sync speeds for the total of the upload tone bins (to left of tone bin 32) and the download bins (to right of tone bin 32) can be calculated. These calculated sync speeds exceed the actual modem sync speeds the modem reports to the user. This excess speed is listed as the "Bit Margin" by the DMT tool and is extra bit load capacity the modem must have for bit swapping and ATM signaling overhead. The actual Bit Margin speed varies from 252 for 768 sync speeds to 480 for 6016 sync speeds. Sync stability is impaired if the modem can't reserve the appropriate Bit Margin speed for the sync speed the modem is trying to achieve. Note: The upload tone bins (the leftmost group) for the 2210 modems are not shown on the DMT chart because they do not list that data in their techreadout pages. The maxrates listed by the DMT tool for the 2210 modem are those actually reported on the modem's techreadout page. Feedback received on this FAQ entry:
