trogers Posted February 2, 2006 CID Share Posted February 2, 2006 You may be facing a combination of 2 problems: 1. Poor line quality or mdem/router problems 2. High traffic in your network To check for the first, do a tracert and post your results To check the second, do a test on this link and post your results for "STATISTICS" and last 2 paragraphs of "MORE DETAILS": http://nitro.ucsc.edu/ Quote Link to comment Share on other sites More sharing options...

trogers Posted February 3, 2006 CID Share Posted February 3, 2006 Read the last line of your test result posted above: "Alarm: Duplex mismatch condition exists: Host set to Full and Switch set to Half duplex" You have to reset your modem or router to auto-sense for duplex. This is why your speed is only half.

FallowEarth Posted February 3, 2006 CID Share Posted February 3, 2006 Try the TCP analyzer again, and also run this: http://www.testmy.net/forum/index.php?action=dlattach;topic=6415.0;attach=9950 Quote Link to comment Share on other sites More sharing options...
trogers Posted February 3, 2006 CID Share Posted February 3, 2006 Some ISP's routers do not respond to pings and tracerts- resulting in request timed out. I now use traceroute. My ISP provides such a service. If your ISP do not have such a service, you can go to this link. The traceroute provided in this link starts from the website's server to any destination, including your own IP address. It is a good way to check your own line: http://www.dnsstuff.com/ Quote Link to comment Share on other sites More sharing options...
FallowEarth Posted February 3, 2006 CID Share Posted February 3, 2006 This is also a good diagnostic tool which will run traceroute and ping. http://www.ks-soft.net/ip-tools.eng/ Quote Link to comment Share on other sites More sharing options...

trogers Posted February 4, 2006 CID Share Posted February 4, 2006 Have you adjusted your modem/router to auto-sense for duplex? Quote Link to comment Share on other sites More sharing options...
trogers Posted February 4, 2006 CID Share Posted February 4, 2006 Explanation of full and half duplex: Refers to the ability to transfer data in both directions. Full-duplex allows for data transfer in both directions simultaneously; half-duplex allows for data transfer only in one direction at the same time. Most current NICs allow for full-duplex communication, theoretically doubling their throughput (i.e. for 100BaseT - 100 Mbps in one direction and 100 Mbps in the other at the same time). Curent Cable/DSL modems are usually half-duplex. Quote Link to comment Share on other sites More sharing options...

trogers Posted February 6, 2006 CID Share Posted February 6, 2006 Click right on the "My Computer" icon of your desktop, click on 'properties. In the open box, click on 'hardware' and then 'device manager'. When a new box open, click on the '+' sign of Network adaptors. Then click right on the name of your NIC (Ethernet Controller) and click 'properties. In the new box, click on 'Advanced' and select the description line with the word 'duplex'. change the value to 'Auto-Sense' and then click 'ok' Then close all your opened boxes, turn off your computer and disconnect power to your modem. Wait for 10 mins, reconnect power to your modem, and turn on your computer. Test your modem duplex setting again at: http://nitro.ucsc.edu/ and post your results.
