How to Troubleshoot a Siemens Speedstream 4200 Modem

Any Internet service provider (ISP) will have its own technical support experts, but it is often wise to know some basic troubleshooting steps so you can address simple problems on your own rather than spending time on the phone with a technical support rep. If you use the Siemens Speedstream 4200 DSL modem, follow some simple steps to troubleshoot problems you may come across.Instructions


Things You'll Need:

  

  1.Reset the modem by unplugging its power cord, waiting a full 30 seconds and plugging it back in. This is a useful troubleshooting step if the modem will not go online or the connection drops intermittently. Allow the modem to run through its entire boot cycle and test the connectivity again.

   2.Unplug the Ethernet cable that attaches the Speedstream to any router or other home networking device you may use and plug it directly into the computer's Ethernet port. This is known as "bypassing" the router, and is also a useful way of troubleshooting no connectivity, slow speeds or intermittent connectivity. After bypassing, reset the modem as in Step 1 and test your connection again.

   3.Reconfigure the modem by opening an Internet browser with an Ethernet cable still attached from the modem to the computer, typing "10.0.0.1" into the address bar and pressing the "Enter" key. You can find information on configuration settings in the Speedstream 4200's manual (see Resources), but you will likely need to contact your ISP's technical support department to gather connection information specific to your Internet service. If your modem is incorrectly configured for your Internet service it will never go online, so reconfiguring the modem can resolve a lack of connectivity.
