SYMPTOMS
When you connect to your Internet service provider (ISP) using a US Robotics 56K WinModem, an "LT Winmodem" or an "HSP Winmodem" you may experience either of the following symptoms at connection speeds above 33.6 kilobits per second (Kbps):


 * The modem may randomly disconnect from your ISP.
 * When you download files, the connection speed may decrease and not resume to its original speed during the session.



CAUSE
This behavior can occur if there is line noise or a resource conflict between the WinModem and another device in your computer.



RESOLUTION
To work around this behavior, follow the steps in the appropriate section below:

Line Noise
If line noise is preventing consistent connections to your ISP, follow these steps:

 Click Start, point to Settings, and then click Control Panel. Double-click Modems. On the General tab, click your modem, and then click Properties. On the Connection tab, click Advanced.  In the Extra Settings box, type one of the following modem initialization strings:

     s32=66

s32=34 </li> Click OK, click OK again, and then click Close.</li> Test to see if the behavior is resolved. If the behavior is not resolved, repeat steps 1-6, using the other modem initialization string in step 5.</li></ol>

Resource Conflict
For information about troubleshooting resource conflicts between modems and other hardware devices, please see the following article in the Microsoft Knowledge Base:
