Troubleshooting Slow Broadband or Windows Network Connections
Last updated: 10/7/02

Q.  How can one fix a slow broadband (cable or DSL) or Windows network connection?

A.  Slow network connections are often caused by bad network cables (especially long ones) or cables that are not run correctly or are not plugged-in all the way.  This is particularly true for custom straight-thru and crossover cables because they are often made improperly by inexperienced, untrained people, are not fabricated with the correct plugs and cable, and/or not properly tested before delivery.  See

for more info. Other causes include defective network adapters and interrupt conflicts (see How to Test a Network Adapter), and other equipment failures, such as hub, Ethernet switch, and router ports.

With this said, another possibility, when using the TCP/IP protocol, is an improper Windows registry setting.  The Windows registry should be backed-up before you start.  To do that, go to Start, Run, enter regedit, Help, and look under Import and Export or in the Help Index under backing-up the registry files... The process is at http://cable-dsl.home.att.net/#IncreasingWindow.  You may find the instructions at the link a little confusing.  So here are mine...  In the second column of the table, choose your version of Windows (e.g., Windows 95/98/Me), right-click the appropriate file (e.g., TCPRW32K.REG) with your mouse, choose Save Target As... in the resulting menu, and select a location to save the file (e.g., your Desktop).  Go to that location and double-click the file.  Restart Windows.  To undo the "damage," use the appropriate file in the fourth column.  Editing (or tweaking) the Windows registry can get you in a lot of trouble and may make Windows unusable.  This procedure is therefore a last resort and should not be done before troubleshoot the hardware.  This procedure may also fix slow Local Area Network connections.  Note:  this procedure may mess-up dial-up connections if you are still using a MODEM.
