    Hello,

    First, as a new member, I would like to thank those of you here for the help you give. Unfortunately, I have encountered a situation which requires me to be more than just a lurker (others seem to have much more knowledge and better opinions than me).

    I have a D-Link WBR-2310 router which I have not had any problems with. I ran one desktop and one laptop hardwired and one laptop wireless. The laptop I used that was hardwired was solely used for downloading via torrents and ftp. Recently, it died and I started using my desktop for my downloads. Almost immediately, I started to lose my internet connection while downloading torrents or ftp files. The problem has grown worse as I will now lose connection simply surfing the web using my desktop. The wireless laptop, however, has had no problems. I can lose hardwire connection with my desktop, plug in my wireless laptop via hardwire, and it works perfectly. I have tried different ports with my desktop, put in a new network card, and used a new ethernet cable...all with the same results--loss of connection. I have also connected my desktop directly to my dsl modem and lose connection. I called my isp and verified my settings. I am left with the fact that my desktop computer is the problem.

    I have ran diagnostics with AVG 7.5, Ad-Aware, and others looking for trojans or viruses--nothing. I ran HiJackThis and will post the results at the end of this message. Nothing has been downloaded or installed on my desktop in the past four weeks since this problem started. I had PeerGuardian 2 installed and thought that might be the problem...uninstalled it and didn't solve the problem.

    Downloading files via BitTornado & Utorrent is when I first discovered the problem. They would start to download and then stop. Downloading FTP was worse...it would kick off almost immediately after starting. Now, even surfing the web for 10-15 minutes causes a loss. When I click "My Network Places", I have two icons--"shareddocuments on my pc" & "D-Link Router". When I lose connection, "D-Link Router" disappears. The only way to restore my internet connection is to reboot my pc. However, I can plug my laptop into the router right after and have no problems on it.

    I am just lost for a solution after weeks of searching others problems in this forum and others. I have found others with this similiar problem but no solutions. I certainly do not want to reinstall windows xp--and that might not even solve the problem.

    I am most grateful to anyone with suggestions, opinions, help, questions...

    Happy holiday to all,
    Drew

    Post an ipconfig/all for your desktop. Also I don't know what you think is "optimal MTU". It should be left at the default 1500.

    Check the time configured on the WBR-2310 under Tools->Time. Make sure it has not reset back to the factory default.

    Do NOT use this WINSOCK fix for XP-SP2! This is ONLY for earlier patch levels of XP. The correct fix for SP2 is:

    TCP/IP stack repair options for use with Windows XP with SP2.

    Start, Run, CMD to open a command prompt:

    Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

    Reset TCP/IP stack to installation defaults. netsh int ip reset reset.log

    Reboot the machine.
